凸极同步电机的参数计算

参数计算是电机设计中的一个关键环节，也是电机理论研究中的一个重要方面。过去这方面的工作虽有一定的进展，但由于对电机中复杂的涡流约束问题缺乏一种普通适用的描述方法，致命一些参数的计算还不能实现直接的电磁场数值求解，因此某些结构下的参数还只能按传统的半经验公式进行计算。针对上述问题，本文首先解决含任意回路的约束涡流场计算问题，实现凸极同步电机参数的通用计算方法，然后与惯用参数计算公式进行比较。对误差过

Parameter Calculation for Salient Pole Synchronous Machines

Parameter calculation is a key step in the design of electric machines, it is also animportant aspect in the theoretical study of electric machines. As lack of general methodto describe the complicated constrained eddy current in eleCtric rnachines, some parameters cannot be calculated by the numerical method,thus parameters under some structures are still being solved by conventional empirical or half-analytical method. In this paper, the calculationsof constrained eddy current fleld with arbitrary circuit are discussed, general calculation forthe parameters of sa1ient pole synchronous machines are realized. Then the comparison withconventional formula are made. Finally, a convenient and accurate analytical formula is givenfor engineering use.
