How Does an Electric Motor Work?

Electric motors work on a very simple principle. According to Hyperphysics, when an electric current is introduced into an magnetic field, a force is generated. An electric motor utilizes looped wires (the same wires that carry the current) which are stationed at right angles to the magnetic field in the electric motor. Because the magnetic field has dual polarities, each end of the wires is moved in a different direction. This creates a turning motion.

Torque is controlled by adding several loops to the armatures and the magnetic field is produced by an electromagnet. This design allows the rotor to be turned by simple electromechanical force, there are very few parts that actually experience any wear and, with those two factors combined, it's possible for electric motors to keep running for an incredibly long amount of time while exhibiting very little wear.
