ABSTRACT:
An induction motor capable of producing an increased torque has a stator for generating a rotating magnetic field, a stator fixed to a shaft, a cylindrical member disposed within an inner space defined by the rotor and rotatably supported by the shaft, and magnets attached to the circumference of the rotor such that the magnets face the rotating magnetic field. The induction motor may be provided with a mechanism for adjusting the effective magnetic force of the magnets. The magnets may be permanent magnets or electromagnets. Also, a synchronizing mechanism may be provided to prevent the cylindrical member from lagging behind the rotor. A linear induction motor includes a straight primary coil assembly and a straight secondary coil assembly. One of the primary coil assembly and the secondary coil assembly is movable relative to the other. Also, a plurality of magnets are disposed in the secondary coil assembly. A disc type induction motor includes a flat circular stator, a disc-shaped rotor, and a flat circular magnet disc on which a plurality of magnets are provided.
