【摘要】：为了有效解决电机温升不易准确计算的难题,该文首先提出基于多领域协同仿真的高密度永磁电机温升计算理念,详细论述温升计算的流程。基于热传导理论,论文导出槽内绕组等效导热系数的计算方法,有效地考虑了漆包线绝缘层、浸渍漆和微孔对电机温升的影响。以一台48槽/8极高密度永磁电机样机为例,基于多领域协同仿真的计算方法,精确计算样机的铁耗、计及集肤效应的交流绕组铜耗,以及永磁体的涡流损耗和电机内的温度场。最后,进行样机的温升试验,温度场计算值与试验结果基本吻合,验证了基于多领域协同仿真的高密度永磁电机温升计算方法的准确性和有效性。
[Abstract]:In order to solve the problem that the temperature rise of motor is not easy to calculate accurately, this paper first puts forward the idea of calculating temperature rise of high density permanent magnet motor based on multi-domain cooperative simulation, and discusses the flow chart of temperature rise calculation in detail.Based on the theory of heat conduction, the method of calculating the equivalent thermal conductivity of the windings in the slot is derived in this paper, and the effect of the insulated layer, the impregnated paint and the microhole on the temperature rise of the motor is considered effectively.Taking a prototype of a 48-slot / 8 extremely high density permanent magnet motor as an example, the iron loss of the prototype, copper consumption of AC winding with skin effect, eddy current loss of permanent magnet and temperature field in the motor are calculated accurately based on the multi-domain collaborative simulation method.Finally, the temperature rise test of the prototype is carried out, and the calculated values of the temperature field are in good agreement with the experimental results, which verifies the accuracy and validity of the temperature rise calculation method based on multi-domain collaborative simulation for high-density permanent magnet motors.
