    Abstract

    The present invention relates to an induced polarization AC motor having maximized efficiency, a stator of the AC motor being provided with 2n number of winding slots and 2n number of induced polarization slits so that when electricity is applied to the stator having just n number of slots distributedly wound, polarization is induced on the magnetic field surfaces on both sides of the winding slots to double the magnetomotive force for operating and rotating the rotor. Here, the rotational direction is determined by the Fleming left-hand rule.

    Claims

    1. An induced polarization AC motor which includes a stator of the induced polarization AC motor, the stator comprising: 2n number of winding slots which are provided in a core formed by stacking silicon steel plates; and 2n number of induced polarization slits (horse-shoe magnet polarization slits) which are provided between the winding slots.sub.; wherein the stator is configured by applying distributed winding only to the n number of winding slots among the 2n number of winding slots, and polarization is induced to magnetic field surfaces at both sides of the winding slots when electricity is applied to the stator, such that a rotor is actuated and rotated by doubling magnetomotive force, and a rotation direction is determined by Fleming's left-hand rule.
