Does a dc motor have an armature
WebApr 1, 2000 · In DC motors, the armature is the rotor, and the field is the stator. Rotor, Commutator and Brushes The contacts of the commutator are attached to the axle of the electromagnet, so they spin with the magnet. … WebDirect current motors vary in size and application, from small-sized motors used in small gadgets/toys to big motors used in cars, elevators, etc. A direct current motor consists of a stator and armature. The stator is the fixed part of the motor, while the armature rotates by a rotating magnetic field caused by the stator.
