  • How Does an Electric Motor Work

    Mar 13 2018  An electric motor creates rotational or circular motion. The central part of the motor is a cylinder called the armature or rotor. The armature holds the rest of the components and is also the part of the motor that spins. Around the armature is the stator which holds insulated coils of wire usually copper.
