“What component causes an electric motor to spin?”

 

We know that Electric motors have two main mechanical parts, a stationary stator that encapsulates a rotating rotor. Now, how is this rotation induced? Well, in addition to having the aforementioned two mechanical components, electric motors has two electrical components. The first electrical component is called the field, which is simply the magnetic field component inside the airgap. This field will turn the armature, which is the primary power producing component in the motor. The armature carries current that is oriented perpendicular to the magnetic field, which in turn will induce a force which will cause a torque to take place. The armature usually consist of several conductive windings for this effect to happen. The field and the armature can be on either on the rotor or the stator but one must only occupy one other.
