DC Motors

DC Motors. Construction very similar to a DC generator The dc machine can operate bath as a generator and a motor. When the dc machine operates as a motor, the input to the machine is electrical power and the output is mechanical power. In fact, the dc machine is used more as a motor.

Commutation

Commutation. It has been seen that currents in armature conductors of a DC generator are alternating. To make their flow unidirectional in the external circuit, we need a commutator.

DC motors are built the same way as generators Armature of a motor connected to a dc power supply

Motor Operation. DC motors are built the same way as generators Armature of a motor connected to a dc power supply When switch is closed a large current flows through the armature winding due to its low resistance Armature is within a magnetic field A force is exerted on the windings
