10. Explain in detail the multi quadrant operation of motor with a neat sketch.

11. Derive the thermal model for both heating and cooling process.

12. Derive the expression for overloading factor K for short time and intermittent periodic duty


ANSWER KEY

1)

2) Steady state temperature depends on power loss, which in turn depends on the output power of the machine. Since temperature rise has a direct relation with the output power, it is termed thermal

loading on the machine.

3)

4) When a motor runs, the wind generates a torque opposing the motion . This is known as the winding

torque. 5) T > Tl – Acceleration

T < Tl – deceleration

6)


7)

1. Continuous duty

2. Short time duty 3. Intermittent periodic duty 4. Intermittent periodic duty with starting 5. Intermittent periodic duty with starting and braking

6. Continuous duty with intermittent periodic loading 7. Continuous duty with starting and braking 8. Continuous duty with periodic speed changes

ANSWER KEY

PART – A

1. State the differences between an induction motor and synchronous motor drive.

An induction motor operates at lagging power factor and hence the converter supplying the same must invariable is a force

commutated one. A synchronous motor, on the other hand, can be operated at any power factor by controlling the field

current

2. List the starting methods of synchronous motor

Using pony motor

Using damper winding

3. What is meant by margin angle of commutation? The difference between the lead angle of firing and the overlap angle is called the margin angle of commutation. If this angle

of the thyristor, commutation failure occurs. Safe commutation is assured if this angle has a minimum value equal to the turn off angle of the thyristor.

4. Name the drive used in cranes.

DC series motor, slip ring Induction motor

5. Draw the motor speed torque characteristics for centrifugal and reciprocating pump

PART – B

6. Compare self-control and separate control of synchronous motor.


7. Explain the operation of ZSI fed synchronous motor.

8. State the advantages and limitations of digital technique in speed control of electric drives Advantages

Easy to design.

Information storage is easy.

Accuracy and precision are greater.

Operation can be programmed. Analog systems can also be programmed, but the variety and complexity of the

available operations is severely limited.

Digital circuits are less affected by noise. As long as the noise is not large enough to prevent us from distinguishing a HIGH from a LOW.

More digital circuitry can be fabricated on IC chips. Limitations

Most physical quantities are analog in nature, and it is these quantities that are often the inputs and outputs that are

being monitored, operated on, and controlled by a system

9. Draw the block diagram for closed loop speed control of microprocessor based separately excited DC motor

drive.

PART – C

10. Draw and explain the closed loop speed control of load commutated inverter fed synchronous motor drive.


11) (ii) Draw and explain the self-control of VSI fed synchronous motor.

Beyond process control with VFDs arable speed motor drives have evolved beyond basic motor control, becoming easier to use while

Figure 2: In recent years, VFD human machine interfaces have included very capable removeable keypads

making them easier to operate and maintain.

Anyone remember working with AC motor variable speed drives circa 1985? Something like a 5 HP drive

might be situated in a freestanding enclosure with dual doors. Inside would be six individual gate driver

boards, with associated ribbon cables and stranded wiring. Numerous potentiometers and rotary switches

were used to configure the equipment, and these could often pose a troubleshooting nightmare.

Early drives like these had rudimentary features such as start and stop buttons, perhaps some form of

acceleration and deceleration ramps, current control and maybe some basic error annunciation. And that

was about it. But for all these imitations, an AC drive might still have been preferable compared to the

alternative of achieving variable speed through some other electrical or mechanical means.

sometimes called inverters but also commonly called variable frequency drives (VFDs), Today's AC driv

are commonplace when motor speed must be adjusted to meet the load. Consumer-grade appliances,

commercial HVAC systems and industrial equipment all empBoy VFDs, sometimes almost as a default.

Ever when the application does not demand variable speed control, VFDs offer other operating benefits,

monitoring capabilities and energy-saving opportunities.

This article looks at the past, present and near future evolution of VFD technologies, and it shows why

designers should always consider applying VFDs for new processing machines and systems, and for many

other types of applications.

VEDs can go most anywhere

Much has changed with VFD technology over the past decades. Today's 5 HP VFD physically fits into a

space of less than one cubic foot. The shrinking size of VFDs is largely due to semiconductor advances, with current densities exceeding 25 amps per square centimeter. The reduced footprint makes it possible

to use these advanced power devices to control output energy to prime movers (motors) in more

applications (Figure 1).

For smaller motor loads of 1HP or less, there are VFDs that literally fit in the palm of one's hand. Design

ratings for VFDs enable them to work in nearly any environment, including sub-zero temperatures down to

-40°F, Advances in heal dissipation permit operation in ambient temperatures up to 50°C or better, which

can be a more challenging condition for VFDs than extreme cold.

Enclosed VFDs are now available with NEMA 12, NEMA 3R and/or NEMA 4X and IP66 ratings, meaning

they can be used in downpouring rain and washdown conditions. Some VFDs are coming to market with

their own enclosed casings that are NEMA 4X outdoor-rated, right out of the box.

While VFDs must offer the right physical arrangement so they can be instaBled near motors in any field

situation, the real VFD developments over the years have been in the brains department.

VFDs get smart

Over the years, VFD configuration was originally performed using switches and knobs and eventually

progressed to various types of specialized on-board and removable/replaceable human machine interfaces.

These keypads offered upload/download capabilities, on-board memory, were hot-pluggable and even

compatible with QR codes for convenience (Figure 2). These were great advances, but even those methods

took some time to navigate through ever-increasing quantities of parameters and functions.

Today's VFDs have graduated to the use of convenient HMI methods already available to everyone: PCs

and mobile devices. Often, the software and mobile apps are free. Instead of only cryptic parameter codes

and difficult-to-enter values, modern VFD HMIs generally provide a much more graphical and simpler user

experience.

Via wiredor wireless networking connections, users can easily interact with VFDs to:

Configure functions Adjust control, operating and drive physics parameters

pload/download settings

Monitor operation Adjust tracking and tuning

Access advanced scope functions

Perform firmware downloads

Beyond basic speed control abilities, another area of advancement involves the significant logic execution

and /O connectivity available right onboard the VFD. For many years, programmable logic controllers

(PLCs) have been used in concert with VFDs to perform control and monitoring first with hardwired lVO

signals, and eventually with networked industrial communication protocols.

Those approaches are still valid, but noW many VFDs have PLC-like programing and control capabilities

buit right in. This becomes relevant when a processing unit must continue to run safely in a local manner

(such as operating an agitator to prevent product from solidifying, while continuing to monitor a hatch

interlock), even if the supervisory control system or network is not available. VFDs can also be employed

for local PID control in a similar manner, making local operatlons more robust, and in some situations VFDs

can control an entire small machine process, such as a pumping station.

Figure 3: Todays VFDs are highly networkable, which reduces field wiring and expands the amount of data

monitoring and advanced configuration and control available to users. Complemented by brawn

VFD brains have also been complemented by electrical brawn through power handling and safety features. Advanced new motor designs are making it possible to achieve improved levels of transmitted power, efficiency and load control accuracy. These include internal permanent magnet, surface permanent magnet motors with active magnetic bearings, pancake traction motors and synchronous reluctance motors, somne with advanced cooling systems. As process designers incorporate these motor types to optimize their designs and meet their demands, compatible VFDs to drive them are needed.

Another VFD advancement involves safety measures. Because VFDs often drive equipment that may present a hazard to workers, it is important to interlock the VFD with suitable safety circuit devices such as emergency stop buttons, guard switches, safety curtains and more. A conventional safety interlock circuit cuts off power to disable the VFD, but this method has limitations and can be difficult and expensive to

implement.

Modern VFDs incorporate safe torque off (STO) and other industry-standard safe control methods such as SS1 or S$2 safe stop modes, safe brake control (SBC), safely limited speed (SLS), safe direction (SDI) and safely limited acceleration (SLA). Circuitry for these functions is qualified by a certification agency to meet requirements. When safety devices are wired to a VFD's STO inputs and a hazardous conditionis detected, the drive will quickly remove power from the outputs via redundant means, with the driven motor positively de-energized and coasting to a stop.

Of course, there may be design considerations and situations where other equipment-stopping methods should be used. But in many cases, the availability of STO and other safe control furnctions is another reason to design new process equipment or upgrade existing installations, using modern VFDs.

The connected VFD

Many process plants have taken advantage of VFD networking capabilities to greatly reduce field wiring and increase the amount of data transfer and control options. Most VFDs now support various Ethernet prolocols, or other industial fieldbuses, for this purpose (Figure 3).

Fber optics are immune to electrical noise and provide much higher performance than copper networking and new wireless broadband networking options are becoming available and may actualy eliminate physical network wiring or fiber while delivering high-performance, real-time control and time-sensitive data transmission. Mehods such as fiber optic wavelength-division multiplexing (WDM) and wireless 5G are making high-speed, high-bandwidth connections more available than ever.

VFDs now incorporate high-speed and redundant-capable ways to flawlessly support the fastest motion control appications and provide accurate data gathering, using protocols such as real time protocol (RTP) parallel redundancy protocol (PRP) and high-availability seamless redundancy (HSR). High-speed manufacturing processes for printing. paper and steel, as well as critical processing for pharmaceutical and food and beverage, demand these reliable integration methods.

Years ago, Users would only be concerned with using a VFD to run a motor at various speeds ass

commanded. Now that even entry-level VFDs have extensive processing, electrical and connectivity options, they are becoming a crucial building block for digital transformation and the industrial internet of things (lloT).

Because VFDs are usually located close to the operating edge, they can be used to gather al sorts of extended information. This includes voltage, current and power information from the drive- along with motor and drive diagnostics, and performance data. The status of I/O points connected to the drive, such as safety or other interlock devices, can also be reported.

The confluence of processing. power and communications advancements are enabling reliable control and data accessibility like never before. Even if these added features are not used immediately, choosing a VFD with these capabilities when designing. equipment is a form of futureproofing, or at least making the system upgrade-ready.

Applications abound

Some of the best applications for an upgrade to a VFD are pumps and fans commonly used in processing industries because significant energy savings may be realized by running the equipment at less than full speed, if the process allows for it. Material conveying and packaging systems also make heavy use of VFDs to adjust equipment speeds based on operating conditions. In many cases, the smooth speed ramping of VFDs prevents the type of damage to product and mechanical systems that can occur when single-speed motors are immediately started at full speed.

Other applications can use VFDs to promote an increased standard of living and a cleaner environment:

Energy production and distribution Desalinization Freshwater treatment and distribution

Wastewater treatment Agricultural water and nutrient transport

Food and beverage Electric vehicles

nakes them practical today and will also provide the lloT capability

Using VFDs for these types of projects makes them practical today and will also. nr

and deep data needed to analyze and optimize operating performance.

Future developments

Like many other salid-state technoBogies, VFDs have followed Moore's Law to some extent

VEDs available today are quite good, even better versions wilt continue to be developed Smalugn the

devices, with ever more processing power and' moe userienduy interaces, will be an increasing trend

Perhaps concepts such as holographic displays and aruficial inteigence for providing operational and e

assistance, which are futuristic by today's standards, will be common soon.

ser

But that doesn't mean process industry users and designers should wait around for the next great thing in

VFDs. The VFDs available today offer high performance and Significant energy savings. More importantly,

they pave the way for end users to- begin digitaf transformation and lo initiatives within their processing

plants.

30 (a) (6M)

An inverter which converts dc voltage into ac voltage and act as a voltage source - Voltage Source

Inverter (VSI). Its capable of supplying variable frequency variable voltage for the speed control of induction motor.


VSI can be operated as a stepped wave inverter (or) pulse width modulated (PWM) inverter. VSI allows a variable frequency supply to be operated from a dc supply. When operated as a stepped wave inverter, thyristors are switched in the sequence of their numbers

with a time difference of T/6 and each transistor is kept on for the duration T/2. (where T – time period for one cycle). (ii) Z-source inverter fed induction motor drive: (6M)

30.(b) Instead of wasting the slip power in the rotor circuit resistance, a better approach is to convert it to ac line power and return it back to the line.

(6M) The static Scherbius drive quite similar to the static Kramer drive, which achieved by replacing the

diode bridge rectifier with a thyristor bridge. The motor can operate on both sub-syn regions and super syn regions, but kramer method can operate only in sub-syn region. During sub-syn region the SCR bridge 1 as rectifier and SCR bridge 2 as inverter – the slip power

returned to the supply. During super-syn region the SCR bridge 2 as rectifier and SCR bridge 1 as inverter – the slip power is pumped to the rotor. The advantage of the s/m is the machine speed can be controlled continuously about 50% above and

below the syn speed with a converter rating of about 50% of the machine capacity. (6M)

Accuracy and precision are greater.


Operation can be programmed. Analog systems can also be programmed, but the variety and complexity of the available operations is severely limited.

Digital circuits are less affected by noise. As long as the noise is not large enough to prevent us from distinguishing a HIGH from a LOW.

More digital circuitry can be fabricated on IC chips.

Limitations: Most physical quantities are analog in nature, and it is these quantities that are often the inputs and outputs that are being monitored, operated on, and controlled by a system.

Solid State Control of Large ac power nctworke rely almost cxcluxivcly on synchronoua

generators.

Synchronous Motor Synchronous motors are built in large units compare to induction

motors (Induction motors arc cheapcr for emallcr ratimgs) aud ucd for constant specd industrial drives.

Main Features of Synchronous Motors Principle of Operation Synchronous Motor Principle of Operation Synchronous Motor

Synchronous motor is a doubly excited machine. - stator winding: three-phase supply to three-phase stator winding.

They are inherenthy not self staring. They require some extermal means to bring their speed close to synchronous

speed to before they are synchronized.

-rotor winding: DC

The 3 phase stator winding carrying 3 phase currents produces 3 phase rotating magnetic flux. The rotor carrying DC supply also produces a constant flux

Therefore some mechanical means s used Initially to bring the rotor to speed very clase to synchronous speed

On achieving synchronous speed, magnetic locking occurs. and the synchronous motor continues to rotate even after removal of external mechanical means

The speed of operation of is in synchronism with the supply

frequency and hence they behave as constant speed motor irrespective of load condition

At a particular instant rotor and stator poles might be of the same polarity (N-N or S-S) causing a repulsive force on thee rotor and the very next instant it will be N-S causing attractive Ths motor has the unique characteristics of operating under

any electrical power factor. This makes it being used in power

factor improvement

force.

But due to the Inertia of the rotor, it is unable to rotate in any direction due to that attractive or repulsive forces, and the rotor remains in standstill condition. Hence a synchronous

motor is not self-starting.

Starting Methods Starting Methods Synchronous Motor-Principle

The rotor acting as a bar magnet will tum to line up with the rotating magne! field. The rotor gets locked to the RMF and rotates unlike inductlion molor at synchronous speed under all load condition

1. Using pony motors - In this method, the rotor is brought to the

synchronous speed with the help of some motor

like induction motor/ DC motor.

2. Using Damper Winding - In a synchronous motor, in addition to the normal

field winding, the additional winding consisting of copper bars placed in the slots in the pole faces.

- The bars are short circuited with the help of end Such a motor is called 'pony motor'. DE TO

rings. - Once the rotor attains the synchronous speed, the

d.c. excitation to the rotor is switched on. - Such an additional winding on the rotor is called

damper winding - This winding as short circuited, acts as a squirrel

cage rotor winding of an induction motor.

- Once the synchronlsm is established pony motor

is decoupled The motor then continues to rotate as

rro synchronous motor.

6. Whnt are the advantages of serles motor?

The advantages of series motors arc,

a. High starting torque

b. Heavy torque overloads.

7. How the D.C. motor is affected nt the time of starting? A D.C. motor is started with full supply voltage across its terminals, a very high current will flow, which may damage the motor due to heavy sparking at commuter and heating of the winding. Therefore, it is necessary top limit the current to a safe value during starting. S. Define and mention different types of braking in a de motor?

In braking the motor works as a generator developing a negative torque which opposes the motion. Types are regenerative braking, dynamic or rheostat braking and plugging or reverse

voltage braking.

9. List the drawbacks of armature resistance control?

In armature resistance control speed is varied by wasting power in external resistors that are connected in series with the armature. since it is an inefficient method of speed control it was used in intermittent load applications where the duration of low speed operations forms only a

small proportion of total running time.

10. What is statie Ward-Leonard drive?

TWO MARKS 1. What is meant by electrical drives?

Systems employed for motion control are called drives and they employ any of the prime movers such as diesel or petrol engines, gas or steam turbines, hydraulic motors and electric mc

for supplying mathematical energy for motion control. Drives employing electric motion are ca

electric drives.

2. Specify the functions of power modulator.

Power modulator performs one or more of the following four functions.

a. Modulates flow of power form the source to the motor in such a manner that motor is

imparted speed-torque characteristics required by the load.

b. During transient operations, such as starting, braking and speed reversal, it restricts

source and motor currents within permissible values; excessive current drawm from

source may overload it or may cause a voltage dip.

3. Mention the different types of drives.

1)Group drive 2)Individual drive

3)Multimotor drive

4. List the different types of electrical drives.

5. What are the advantages of electric drives?

1) They have flexible control characteristies. the steady state and dynamio

characteristics of electrical drives can be shaped to satisfy load requirements.

2) Drives can be provided with automatic fault detection systems, programmable logic

controllers and computers can be employed to automatically ctrl the drive operations in

a desired sequence.

3) They are available in which range of torque, speed and power.

4) It can operate in all the four quadrants of speed-torque plane. Blectric braking gives smooth deceleration and increases life of the equipment compared to other forms of

braking.

5) Control gear required for speed control, starting and braking is usually simple and

easy to operate.

6. What are the functions performed by electric drives?

Various functions performed by electric drives include the following.

a. Driving fans, ventilators, compressors and pumps etc.

b. Lifting goods by hoists and cranes

c. Imparting motion to conveyors in factories, mines and warehouses and

d. Running excavators and escalators, electric locomotives, trains, cars, trolley buses, lifts and drums winders etc

7. What are the disadvantages of electric drives?

The disadvantages of electric drives.

a. Electric drives system is tied only up to the electrified area.

b. The condition arising under the short circuits, lenkage from conductors and breakdown of overhead conductor may lead to fatal accidents.

c. Failure in supply for a few mih tHy ParHy SLMhe whole system

8. What are the advantages of group drive over individual drive?

The advantages of group drive over individual drive are

a. Initial cost: Initial cost of group drive is less as compared to that of the individual

drive.

b. Sequence of operation: Group drive system is useful because all the operations are

stopped simultaneously.

C. Space requirement: Less space is required in group drive as compared to individual

drive.

d. Low maintenance cost: It requires little maintenance as compared to individual

drive.

9. What the group drive is not used extensively.

Although the initial cost of group drive is less but yet this system is not used

extensively because of following disadvantages.

a. Power factor: Group drive has low power factor

b. Efficiency: Group drive system when used and if al the machines are not working

together the main motor shall work at very much reduced load.

c. Reliability: In group drive if the main motor fails whole industry will come to stand

still.

d. Flexibility: Such arrangement is not possible in group drive i.e., this arrangement is

not suitable for the place where flexibility is the prime factor.

e. Speed: Group drive does not provide constant speed.

f. Types of machines: Group drive is not suitable fro driving heavy machines such

STUDENTSFOCUS.COM as

cranes, lifts and hoists etc.

10. Write short notes on individual electric drives.

In individual drive, each individual machine is driven by a soparate motor. This motor also imparts motion to various other parts of the machine. Examples of such machines are single spindle drilling machines (Universal motor is used) and lathes. In a Jathe, the motor rotates the spindle, moves the feed and also with the help of gears, transmits motion to lubricating and cooling pumps. A three phase squirrel cage induction motor is used as the drive. In many such applications the electric motor forms an integral part of the machine

11. Mention the different factors for the selection of electric drives?

1) Steady state operation requirements. 2) Transient operation requirements. 3) Requirements related to the source.

4) Capital and running cost, maintenance needs, life.

5) Space and weight restriction.

6) Environment and location.

Totally enclosed type

Flame proof type

15. Mention the different types of classes of duty

Continuous duty

Discontinuous duty

Short time duty

Intermittent duty

16. What is meant by regenerative braking?

Regenerative braking occurs when the motor speed exceeds the synchronous speed. In

this case the IM runs as the induction mle is converting the mechanical power into

electrical power which is delivered back to the electrical system. This method of

braking is known as regenerative braking.

17. What is meant by dynamic braking?

Dynamic braking of electric motors occurs when the energy stored in the rotating

mass isdissipated in an electrigal rssistancehisrequires a motor to operate as a gen.

to convert the stored energy into ele trical

18. What is meant by plugging?

It is one method of braking of IM. When phase sequence of supply of the motor running at the speed is reversed by intorchanging connections of any two phases of stator with respect to supply terminals, operation shifts from motoring to plugging

region.

19. What is critical spced?

It is the speed that separates continuous conduction from discontinuous conduction mode.

20. Which braking is suitable for reversing the motor?

Plugging is suitable for reversing the motor.

21. Define equivalent current method

The motor selected should have a current rating more than or equal to the current. It is alsonecessary to check the overload of the motor. This method of determining the power rating of themotor is knowm as equivalent current method.

22. Define cooling time constant

It is defined as the ratio between C and A. Coolng time constant is denoted as Tau

Tau C/A

Where C-amount of heat required to raise the temp of the motor body by 1 degre Celsius

Aamount of heat dissipated by the motor per unit time per degree Celsius.

23. What are the methods of operation of electric drives?

Steady state

acceleration includingsatSTUDENTSFOCUS.cOM

deceleration including starting

The motor operates in two mode: motoring and braking. In motoring, it converts

electrical energy into mechanical energy which supports its motion. In braking, it

works as a generator, converting mathematical energy into electrical energy and thus

opposes the motion. Motor can provide motoring and braking operations for both

forward and reverse directions.

25. What is meant by mechanical characteristics?

The curve is drawn between speed and torque. This characteristic is called mechanícal

characteristics.
