There is no basic difference between DC motor and generator. The same DC motor can be used interchangeably as a generator.
COMPARISON BETWEEN MOTOR AND GENERATOR:
MOTOR
Rotor is rotate.
Converting Electrical Energy into mechanical energy.
No prime mover needed.
Current supplied in armature.
Convert electrical energy into mechanical energy.
Motor Force direction is given by Fleming’s Left-Hand rule.
Supply is converting to mechanical energy and End by the generator.
Armature is rotate
Converting of Mechanical Energy into electrical energy
Prime mover is used by generator.
Current taken from Armature.
Convert mechanical energy into electrical energy.
Generator E.M.F direction is given by Fleming’s Right-Hand rule.
Mechanical energy is converting to electrical energy and End by the User or loads.
1. A brushless exciter is a small AC generator with its field circuit mounted on the stator and its armature circuit mounted on the rotor shaft.
2. The three-phase output of the exciter generator is rectified to direct current by a three-phase rectifier circuit also mounted on the shaft of the generator and is then fed into the main DC field circuit.
By controlling the small DC field current of the exciter generator, it is possible to adjust the field current on the main machine without slip rings and brushes.
