Determine magnetic pole, rotary pole assembly.There is introversive half hole slot rotary pole groove side；Described rotary pole assembly has pole lamination
The magnetic pole body of composition, magnetic pole body edges be provided with rotary pole groove to the hole slot of extroversion half that half hole slot is corresponding, magnetic pole
Body is provided with magnetic pole groove, and magnetic pole is placed in magnetic pole groove.
Fabrication hole is also provided with above-mentioned magnetic pole body, is easy to engagement tool to realize the rotation of rotary pole assembly.
The application method of permanent-magnet motor rotor disclosed in this invention, it is characterised in that comprise the following steps：
1）Into off working state, that is, when being processed, transport or repair, assembling：
The embedded and opposite polarity magnetic pole of normal operating conditions in the magnetic pole groove of rotary pole assembly, make itself and fixed magnetic
Pole forms closed magnetic circuit in rotor core, so that whole rotor does not show magnetic externally；
Take an alignment pin to be put into the positioning hole that the above-mentioned hole slot of introversion half and export-oriented half hole slot are correspondingly formed, make rotary magnetic
Pole assembly is relatively fixed with rotor core；
2）During into normal operating conditions：
Alignment pin is taken out, rotary pole assembly is rotated in the rotary pole groove of rotor core；
Rotary pole assembly is rotated, the polarity of magnetic pole is met the magnetic structure requirement of working condition；
Alignment pin is reentered into positioning hole, rotary pole assembly is relatively fixed with rotor core；
3）When being again introduced into off working state：
Alignment pin is taken out again, rotary pole assembly is rotated in the rotary pole groove of rotor core；
Rotary pole assembly is rotated, makes the opposite polarity when polarity and working condition of magnetic pole, so that whole rotor pair
Do not show magnetic outside；
Alignment pin is reentered into positioning hole, rotary pole assembly is relatively fixed with rotor core.
Permanent-magnet motor rotor disclosed in this invention and its application method, when being processed, transport to rotor, assembling,
Portion magnetic pole in built-in tangential magnetic circuit is made into rotary structure, it is directly formed magnetic inside rotor core with fixed magnetic pole
Field loop, makes whole rotor not show magnetic externally, avoids due to the interference of high-intensity magnetic field in operation process, the work that may be brought
Inconvenience and potential safety hazard, have simple and easy, and cost is low, improves the good effect of production efficiency and safety guarantee.
