The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The permanent magnetism face with stator of the utility model pastes the formula rotor, comprises the plurality of fixed sheet, is provided with lamination between described adjacent two stators; The middle part of stator has the stator axis hole; The middle part of lamination has and the corresponding to lamination axis hole of stator axis hole shape, and cross-under has axis body that all stators, lamination are fixed together in the axis hole, also is evenly equipped with fastener hole on the stator of stator axis hole, lamination axis hole periphery, the lamination; Cross-under has fixed lever in the fastener hole; The diameter of stator is greater than the diameter of lamination, and the outer rim of stator is evenly equipped with cell body or the hole more than 2, and cross-under has permanent magnet in the cell body of all stators or the hole.Several stators and several certain thickness laminations are spaced; Fastener hole on the stator aligns with fastener hole on the lamination; The stator axis hole aligns with the lamination axis hole, and the fastener hole that passes on the spaced stator through fixed lever is fixed into as a whole with fastener hole on the lamination.Hole or cell body consistent with the permanent magnet shape on several stators also align, and permanent magnet is placed in hole or the cell body, and axis body is placed in the axis hole.Reasonably the stator structure can effectively reduce the loss on the stator, avoids traditional permanent magnetism face to paste the metal coating commonly used of formula rotor and puts the eddy current loss of can not ignore, and reduces rotor heating, improves electric efficiency.
As preferably, the cell body that described stator outer rim is uniformly distributed with is a circular arc, and the shape of permanent magnet is consistent with the cell body shape.Can guarantee that like this stator provides the reliable protection that is positioned to permanent magnet.
As preferably, described lamination is that certain thickness silicon steel sheet lamination is processed, and perhaps powdered metallurgical material is processed or solid core is processed.To guarantee good magnetic property.
As preferably, described stator is processed by iron, aluminium, plastics or nylon.Stator can be processed by other metal material or nonmetallic materials.
As preferably, the outer edge of the cell body that described stator outer rim is uniformly distributed with has breach.Can guarantee that motor has littler physics air gap.
Therefore, the utility model adopts stator simplification face to paste the technique for fixing of permanent magnet in the formula PM rotor, selects suitable material for use; Effectively protect permanent magnet during the motor high-speed cruising; Reasonably the stator structure can effectively reduce the loss on the stator, avoids traditional permanent magnetism face to paste the metal coating commonly used of formula rotor and puts the eddy current loss of can not ignore, and reduces rotor heating; Improve electric efficiency, simple and reasonable for structure.
