Motive power generating apparatus utilizing energy of permanent magnet

DETAILED DESCRIPTION What is claimed is: 1.
Motive power generating apparatus utilizing energy of permanent magnet, comprising: a stator having a stator core, a plurality of stator poles and a plurality of windings disposed around the respective stator poles; a rotor having a rotor core rotatably supported in said stator and a plurality of rotor poles arranged along the outer periphery of the rotor core, each said rotor poles including a permanent magnet member arranged corresponding to said respective stator poles, said permanent magnet members arranged in such a manner that different polarities thereof are adjacent each other and a pole piece of magnetic material disposed on each of the permanent magnet members, said pole piece having an extension in a direction of rotation of said rotor core; and means for supplying electric current to the windings of the stator so that the adjacent stator poles are energized in opposite polarities, said electric current supplying means changing direction of the current supplied to the respective windings so as to alternate the polarity of each said stator poles when the rotor poles face on the corresponding stator poles which have the opposite polarity, whereby magnetic energy of said permanent magnet members as well as magnetic energy of said stator poles by the electric current input by said electric current supplying means is converted into motive power output.
2.
Motive power generating apparatus as set forth in claim 1, wherein said pole piece of the rotor pole has an outer peripheral length longer than the distance between the two adjacent stator poles.
3.
Motive power generating apparatus as set forth in claim 1, wherein said stator is substantially formed into a ring shape and the even-numbered stator poles are projectingly disposed along the inner peripheral portion thereof at equal intervals.
4.
Motive power generating apparatus as set forth in claim 1, wherein each said pole piece has an arc-shaped outer peripheral profile corresponding to the inner periphery of the stator pole
