Permanent magnet motor novel rotor disclosed in this invention, has rotor core, is overrided to form by rotor iron core lamination, middle part has axis hole, it is characterized in that, described rotor core also has fixed magnetic pole groove, rotary pole groove, wherein arranges fixed magnetic pole, rotary pole assembly respectively.Rotary pole groove side has introversive half hole slot; Described rotary pole assembly has the magnetic pole body that pole lamination is formed, magnetic pole body edges be provided with in rotary pole groove to extroversion half hole slot that half hole slot is corresponding, magnetic pole body is provided with magnetic pole groove, places magnetic pole in magnetic pole groove.
Above-mentioned magnetic pole body can also be provided with fabrication hole, be convenient to the rotation that engagement tool realizes rotary pole assembly.
The using method of permanent magnet motor novel rotor disclosed in this invention, is characterized in that, comprise the steps:
1) enter non operating state, namely carry out processing, transport or keep in repair, when assembling:
Embed and the opposite polarity magnetic pole of normal operating conditions in the magnetic pole groove of rotary pole assembly, make itself and fixed magnetic pole form closed magnetic circuit in rotor core, thus make whole rotor externally not aobvious magnetic;
Get the location hole that an alignment pin puts into above-mentioned introversion half hole slot and export-oriented half hole slot correspondence formation, make rotary pole assembly relative with rotor core fixing;
2) when entering normal operating conditions:
Take out alignment pin, rotary pole assembly can be rotated in the rotary pole groove of rotor core;
Rotate rotary pole assembly, make the polarity of magnetic pole meet the magnetic structure requirement of operating state;
Alignment pin is reentered into location hole, makes rotary pole assembly relative with rotor core fixing;
3) when again entering non operating state:
Again take out alignment pin, rotary pole assembly can be rotated in the rotary pole groove of rotor core;
Rotate rotary pole assembly, make the polarity when polarity of magnetic pole and operating state contrary, thus make whole rotor externally not aobvious magnetic;
Alignment pin is reentered into location hole, makes rotary pole assembly relative with rotor core fixing.
Permanent magnet motor novel rotor disclosed in this invention and using method thereof, rotor is processed, transports, when assembling, portion magnetic pole in built-in tangential magnetic circuit is made rotary structure, make itself and fixed magnetic pole directly form field circuit in rotor core inside, make whole rotor externally not aobvious magnetic, avoid the interference due to high-intensity magnetic field in operation process, the work inconvenience that may bring and potential safety hazard, have simple, cost is low, enhances productivity and the good effect of safety guarantee.
