DC Motors - University of Rajshahi
2013-7-17 Commutation in DC Motor In order to produce unidirectional force (or torque) on the armature conductors of a motor, the conductors under any pole must carry the current in the same direction at all times. The function of commutator and brush gear in a dc motor is to cause the reversal of current in a conductor as it moves from one side of a

Working Principle of DC Motor - Study Electrical
2019-2-10 There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are seldom used in ordinary applications because all
