| 摘 要： | 以1台117kW、60000r/min的超高速永磁同步发电机为例,建立了二维瞬态电磁场数学模型,利用场路耦合时步有限元法分析了电机的磁场分布和气隙磁密,给出了输出电压、电流随转速变化的关系,并与试验结果进行了对比;根据流体力学原理和传热学理论,采用有限体积法计算了冷却介质三维流动时电机内及冷却介质的温度;研究了电机护套分别采用铜屏蔽层、碳纤维复合材料、热喷陶瓷涂层时转子的涡流损耗分布情况,给出了碳纤维复合材料导电性和铜屏蔽层厚度对转子涡流损耗的影响规律;最后通过对电机转子护套采用不同材料和结构时电机各部分温度的对比分析,得出了护套材料和结构对电机温度分布的变化关系,对超高速永磁电机设计具有一定的指导意义。

| Abstract: | Taking a 117 kW 60 000 r/min super high speed permanent magnet generator as an example,the mathematical model for 2D transient electromagnetic field analysis was established,and then magnetic flux lines and air-gap flux density were analyzed by using circuit-field coupled time-stepping finite-element method.The variations of terminal voltage and windings current with time were obtained,which are compared with the test data.With CFD principles and heat transfer theories,the temperature distributions of gener... |
