摘要:
 首先根据 510 k W 盘式电机的电磁设计参数以及热物性参数建立了三维温度场流场耦合模型,分析了额定工况下电机发热部件的温度分布,接着对样机进行了温升实验。针对温升实验电机温度偏高进行了改进性研究探索。主动降温方面,建立了三维轴向磁通电机模型,从铁耗理论模型和电磁仿真模型角度分析了不同牌号硅钢片,在空载和负载工况下,铁耗瞬态变化趋势。被动降温方面,基于建立的三维耦合模型,分析了入口流速、端盖材质、额定负载和过载对电机定转子最高温度影响。接着分析了不同水道模型、不同入口流速条件下,对壁面对流换热系数以及入口和出口压力损失变化规律。通过以上温升影响因素的分析,为后续盘式电机散热冷却改进设计提供理论依据。
Abstract:
 First of all,according to electromagnetic parameters and thermal physical parameters of510 k W disk-type motor,the 3D liquid-solid coupling model was built. The temperature distribution ofmotor heating parts was analyzed under the rating condition,and then the temperature rise test of prototypewas performed. For the case that the temperature of motor is relatively high,affecting factors of tempera-ture rise test were studied from the perspective of temperature reduction actively and passively. As for ac-tive temperature reduction,a 3D axial flux PMSM model was put forward. Changing trends of iron coreloss were analyzed under the no-load and load conditions,using different brands of silicon steel sheetbased on the theoretical model of iron core loss and electromagnetic simulation model. As for passive tem-perature reduction,the influence factors on the highest temperature of stator and rotor were analyzed,which include inlet velocity,end capmaterial,and different load based on the 3D liquid-solid couplingmodel. Finally,the convective heat transfer coefficient and pressure loss between inlet and outlet werestudied,which change with different water channel type and inlet velocity. Through above analysis of in-fluential factor on temperature rise,the theoretical foundation is laid for improving the thermal manage-ment of disk-type motor.
