One of the Original Induction Motors

Motor with a short-circuit rotor was demonstrated by Tesla in his historic lecture before AIEE at Columbia University (May 16th,1888). The operation of the motor is based on Tesla's invention of creating the rotating magnetic field using polyphase alternating currents. The motor consists of three main parts –rotor: rotating part which creates mechanical energy; stator: housing that hold everything together and coils: a copper wire wound spirally around the base. Applying alternating current through the coil system leads to formation of the rotating magnetic field, which affects the rotor of the system. The rotation of the magnetic field is induced, thus creating movement, energy.
