the INDUCTION motor does not have any DIRECT supply onto the rotor; instead, a secondary current is induced in the rotor. To achieve this, STATOR windings are arranged around the rotor so that when energised with a polyphase supply they create a rotating magnetic field pattern which SWEEPS past the rotor. This changing magnetic field pattern can induce currents in the rotor conductors. These currents interact with the rotating magnetic field created by the stator and the rotor will turn.
