An electric motor is oriented around magnetism in that motors use magnets to transform electrical energy into mechanical motion. Motors rely upon two small permanent magnets and one electromagnet created by winding wire around metal. This electromagnetic coil acts as an electrical conductor; as the current passes through, it fuses together multiple fields from separate turns of wire to create a stronger magnetic field. Attracting and repelling forces between the smaller field magnets create a rotational motion, which the rotor’s electromagnet sustains by reversing polarities.
Rotors have the above three poles to ensure better dynamics, prevent the armature from getting stuck or commutator from shorting out the battery.
