GENERATOR DC (Direct Current )

Konstruksi Generator :1) Kumparan tembaga ABCD berputar

diantara magnit permanen N-S2) Kedua ujung kumparan dihubungkan

dgn Slip Ring ‘a’ dan ‘b’.3) Arus induksi yang dihasilkan melalui

sikat-sikat (borstell) ke beban R

Prinsip Generator :Bekerja berdasarkan konversi energi mekanik yang diberikan dan menghasilkan Energi Listrik Dasar Generator Listrik :1) Medan Magnet Utama 2) Konduktor yang bergerak akibat fluks yang memotong batang konduktor.

Magnetic Frame/Yoke(Provides mechanical support for poles / protecting cover for the whole machine and magnetic produced by the poles)

Poles Cores and Poles ShoesProvides mechanical support for poles

Pole Coils or Field Coils Armature Core Armature Winding/Conductor Commutator Brushes and Bearings

GENERATOR DC (Direct Current )

Armature Core and Windings Houses the armature conductor

/ coil Resultance to the flux passing

through the armature from a N-pole to a S-pole

Laminations approximately 0.06 mm thick

Former-wound (Windings) The conductors are placed in

armature slots. Insulation for armature

conductors (Hard wooden/fibre wedges)

GENERATOR DC (Direct Current )

Commutator Converts AC inducted Insulated by thin layers of

mica Commutator segment is

connected to the armature conductors (Copper lug/strip)
