Description
Technical field
The utility model relates to motor fields, more particularly to a kind of stator structure of high-grade drives motor.
Background technique
At present due to neodymium iron boron class permanent magnet rise in price, cause compressor cost pressure larger.To reduce cost, improve
Electric efficiency, engineers and technicians propose many methods and measure: specifically including that is made using ferrite-type motor, reduction
With neodymium iron boron class permanent magnet trade mark etc..Ferrite-type permanent magnet magnetic performance is poor, and energy density is lower, is unfavorable for the small of compressor
Type；And reduce merely the neodymium iron boron class permanent magnet trade mark then face permanent magnet demagnetize under bad working environments increased risk the problem of.
Existing permanent magnet motor stator structure, two layers permanent magnet mounting groove end magnetic bridge is general and without optimization design, the magnetic line of force compared with
Difficulty passes through, and the internal layer ferrite permanent magnet that armature field acts directly on permanent magnet end position and causes magnetic property weaker occurs
End demagnetization.Therefore, it is necessary to be further improved.
Summary of the invention
The utility model is mainly solving the technical problems that provide a kind of stator structure of high-grade drives motor, Neng Gousuo
Firmly de-magnetization point, motor are suitable for high current, high torque end product for a long time.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of high-grade drives
The stator structure of motor, which is characterized in that including magnetic shoe retainer, two magnetic shoe installations are symmetrically arranged on the magnetic shoe retainer
Slot, magnetic shoe mounting groove inside ferrite magnetic shoe, the side of the ferrite magnetic shoe is provided with neodymium iron boron (NdFeB) magnetic tile, the neodymium iron
Magnetizer is additionally provided on the outside of boron magnetic shoe, the neodymium iron boron (NdFeB) magnetic tile and magnetizer are set to one end of magnetic shoe mounting groove, described
It is contacted two-by-two between neodymium iron boron (NdFeB) magnetic tile, ferrite magnetic shoe and magnetizer.
In one preferred embodiment of the utility model, the ferrite magnetic shoe is tile like structure.
In one preferred embodiment of the utility model, the neodymium iron boron (NdFeB) magnetic tile and magnetizer uniform arcuate shape structure.
The beneficial effects of the utility model are: the stator structure of the utility model high-grade drives motor, can lock and move back
Magnetic dot, motor are suitable for high current, high torque end product for a long time.
