The method have the benefit that due to the hysteresis quality of air when rotor rotates, it cannot with rotor rotation
Synchronizing leads in magnet ring module that air pressure and rotor exterior pressure are unequal, cause air due to rotor rotation and shape
At pressure difference, the effect that pressure-air is flowed to low-pressure air can be then generated, so being formed in single magnet ring module from wind-guiding
Channel core outer circle, wind guide tank, thermal trough I air-guiding aisle, and be to communicate since the thermal trough I in multiple magnet ring modules is axial
, it is most communicated afterwards through being equipped with the end plate of thermal trough II with outside air, realizes self cooling circulation canal.Motor speed is higher, circulation
Effect is better, so the heat that distributed in rotor and stator coil can be directed at motor side Board position, direct and rotor
Outside forms heat exchange, to play the role of reducing rotor internal temperature.Simultaneously as being divided into multiple magnet rings from axial
Module can magnetize again after magnetic pole is packed into magnet ring module, thus assembly it is simple and be conducive to rotor core and rotating member it
Between elastic conjunction thus greatly reduced in particular, being fixed together between magnetic pole and magnet ring module by being bonded or welded
The thickness of retaining ring optimizes the air gap between rotor and stator, improves electric efficiency.
