A simple electric motor consists of the following parts:

Armature: Also called a rotator. It is an electromagnet made by coiling thin wire around two or more poles of metal core.
Field magnet: A permanent magnet. The field magnet could be an electromagnet in large motors. However, permanent magnet is used in small motors to save power.
Axle: The armature has an axle to hold it inside the body of the motor and let it rotate.
Commutator: A pair of plates attached to the axle. These plates are c
