<p>This invention relates to a logical structure and high efficiency drive motor, the features that the stator is a soft-iron cylinder which is proper thickness. The inner wall are secured four magnetic poles of the same size which are made of tiling-like permanent magnet, and the pole of adjacent magnets are contrary each other. The rotor is a soft-iron cylinder, out of which are secured twelve or more magnetic poles of the same size which are made of tiling-like permanent magnet, and the magnetic poles are arranged contrarily and the of distance adjacent poles is 2 mm around. On the tiling-like magnets secured the tiling-like soft iron which accordingly has the same outer diameter and size as each of them, and their thickness will be changed accordingly to the magnetic field strength and magnetic induction ability of the magnetic poles. The invention has advantage of simple structure, reliable working, high efficiency and could be widely use for industry and everyday living.</p> |
