| 摘 要： | 采用定子面电流沿电机轴向分布不变的假设,对复合转子异步电机的磁场进行了二维与三维解析求解,得到了描述电机磁场的各电磁量的解析表达式.基于磁场求解的结果,通过引入坡印亭向量得到了复合转子阻抗等参数的计算公式.样机的实验结果与计算结果相吻合,证明了磁场分析与参数计算的正确性.

| Abstract: | On the assumption that the stator surface current is kept constant along the axial direction , the field for a composite-rotor induction motor is calculated and all the expressions for quantities describing the field are obtained. The expression for rotor impedance of a composite-rotor induction motor is derived by the Poynting vector. The machine performance calculated by the method proposed is found to be in good agreement with that measured on a prototype motor. |
