The present invention relates to an AC motor with efficiency improved by induced polarization (horse-shoe magnet polarization), and more particularly, to an induced polarization AC motor in which 2n number of winding slots and 2n number of induced polarization slits are provided, and distributed winding is applied only to the n number of winding slots among the 2n number of winding slots, such that polarization is induced, by the induced polarization slits, to magnetic field surfaces at both sides of the winding slots, thereby doubling magnetomotive force, and thus improving efficiency of the motor.
One of the global issues that have to be solved by physics in the twenty-first century is an “energy problem”.
AC motors currently use 50% or more of the overall electrical energy.
If a new and innovative technology capable of significantly improving efficiency of the AC motor is developed, the technology can serve to solve the energy problem.
The present invention provides a new and innovative technology capable of significantly improving efficiency of an AC motor.
The present invention provides an induced polarization AC motor which includes a stator of the induced polarization AC motor, the stator including: 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, in which 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.
