【摘要】：磁性齿轮复合电机无论是机械结构还是磁路结构,均比普通永磁同步电机复杂,如何高效准确地计算出铁损耗,对该类电机的设计与优化具有重要的意义。该文设计制造了一台磁性齿轮复合电机样机,并采用有限元时步法进行了详细计算。在此基础上,通过对每一个铁心单元的磁密变化进行分析,计算了该复合电机的铁损耗计算。在计算磁滞损耗时,应用通常用于机械应力应变迟滞计算的雨流计数法,快速统计出构成局部磁滞回环的峰谷点,从而计算出局部磁滞损耗。最后通过两个试验步骤,把电机的铁损耗从空载损耗中分离出来,所得的试验结果验证了所述方法的有效性。
[Abstract]:The magnetic gear composite motor is more complicated than the ordinary permanent magnet synchronous motor in both mechanical structure and magnetic circuit structure. How to calculate the iron loss efficiently and accurately is of great significance to the design and optimization of this kind of motor. In this paper, a prototype of magnetic gear composite motor is designed and manufactured, and the finite element time step method is used to calculate it in detail. On this basis, the iron loss of the composite motor is calculated by analyzing the magnetic density variation of each core unit. In the calculation of hysteresis loss, the rain flow counting method, which is usually used to calculate mechanical stress and strain hysteresis, is used to calculate the peak and valley points which constitute the local hysteresis loop, and then the local hysteresis loss is calculated. Finally, the iron loss of the motor is separated from the no-load loss by two experimental steps. The experimental results show that the proposed method is effective.
