n the fact that a current-carryingconductor, when placed in a magnetic field, will have a force
exerted on the conductor proportional to the current flowing in the conductor and to the strength of the magnetic field. In alternating current motors, the windings placed in the laminated stator core produce the magnetic field. The aluminum bars in the laminated rotor core are the currentcarrying conductors upon which the force acts. The resultant action is the rotary motion of the rotor and shaft, w
