| 摘 要： | 对多相交流电机端部漏感系数进行了计算与测量.在用气隙电流代替气隙的作用,用镜像电流代替铁磁媒质的作用,把电机端部磁场问题简化为均匀空气媒质中磁场问题的基础上,根据毕奥-萨法定理,对交流电机端部磁场作了进一步分析,推导出了定子线圈磁通量的有关计算公式,并对一交流电机端部的自感互感系数进行了计算和测量.

| Abstract: | Based on the Biot Sova Law, the end winding leakage inductances of multiphase electric machines are calculated and measured. The air gap is replaced by the gap current and the iron magnet is replaced by the mirror image current. The practical end field of electric machines is simplified to a question about an electric magnet field in the air. The calculating equations of the stator end winding leakage flux and inductances are conducted. Some calculated and measured results are also given. |
