WebbDefine Motor. A device that converts electrical energy into mechanical energy. Define armature. The moving part of a motor or generator containing a shaft, insulated … WebbIn a DC motor, the magnetic field uses a rotating force or a torque over to the winding to rotate. On the other hand, in a DC generator, mechanical torque is applied in the direction of the shaft to maintain the armature winding motion. In both cases, commutators reverse the direction of current flow throughout the winding.
