Induction motor with interior exposed. This type of alternating current (AC) motor comprises a static stator (pale grey casing), which contains electromagnets (blue) arranged to form a hollow cylinder. Within the stator sits a moving rotor (shiny), which is mounted on the motor's shaft. The rotor also contains electromagnets (not seen). To make the rotor turn, the magnetic field of the stator is altered so that the poles of the rotor are attracted by the opposite poles on the stator. As the magnetic field of the stator rotates, the rotor is forced to rotate with it.
