10kW超高速永磁电机三维瞬态温度场计算
Calculation of 3D Transient Temperature Fields of the 10 kW Ultra High Speed PM Motor
摘要
Abstract
In order to check the cooling effect of the motor by using the spiral water jacket,a three-dimensional temperature field of the motor was studied by finite element method for a ultra-high speed PM motor with a rated 10 kW,90 000 r/min considered stator iron loss,stator copper loss,rotor iron loss and rotor wind friction loss.The results showed that the air in the stator-rotor narrow gap seems to impose a heat sealed on the rotor.Therefore,it would not very effectively to cool the rotor with a significant loss power by the spiral water jacket only.Some additional cooling method,such as forced air cooling,should be applied in order to reduce the rotor temperature further.The results provideed an important reference for the thermal design of high power high speed PM motor.关键词
