双定子永磁同步发电机(DSPMSG)包括内外两个定子和中间的转子,一般的电磁场计算软件计算比较困难。建立DSPMSG的磁路计算模型,利用铁磁材料的磁化特性曲线考虑磁场饱和,并同时考虑内、外两套绕组电枢反应对永磁磁场的影响,可对电机的性能参数进行计算,便于设计变量的及时快速调整。通过对1台3.3 kW样机的磁路计算和有限元计算的比较,证明了该模型的有效性和实用性。

Doublestator permanent magnet synchronous generator (DSPMSG) had two stators and one inbetween rotor. It was not easy to carry out electromagnetic field calculation with common software. Magnetic circuit model for DSPMSG was established. The model considered magnetic saturation according to the magnetization characteristic curve of ferromagnetic material, and took into account the influence of armature reaction of inner and outer windings on permanent magnet field. It was convenient for the timely adjustment of design variables. The calculation results using the magnetic circuit model of a 3.3 kW prototype met with the results of finite element calculation, which indicated the practicability and validity of the model.
