Document Type and Number:
WIPO Patent Application WO/2005/064767
Kind Code:
A1
Abstract:
The present utility model provides a permanent magnet motor, which includes a stator and a rotor fixed coaxially, in which the rotor is made of laminated multi-layer silicon steel sheets with rotor teeth and rotor slots, characterized in that the stator is provided with at least two permanent magnets and at least two laminated multi-layer silicon steel sheets arranged alternately with the permanent magnets, in that two stator teeth are provided on each laminated multi-layer silicon steel sheet, and in that armature windings are bedded in phase-shifting slots provided between two stator teeth. Consequently, the disadvantages in the prior art can be solved. Meanwhile, the motor has better magnetic density wave form of sine wave in the air gap, fewer harmonics, and higher winding rate of iron-copper and copper-iron. The winding has simple structure and the cost is low and so on.
