Analysis for magnetic field of srm is very complicated since the flux waveforms in different parts of the motor vary with motor phase , stator pole and rotor number , also with the winding connections , etc , which results in the srm losses , especially iron loss calculation difficult . the temperature analysis due to the losses has become a study hot spot
Sr電機鐵心的磁通波形不僅與電機的相數有關,還與定、轉子齒極數、定子繞組連接方式等密切相關,從而使得sr電機磁場分析很復雜,復雜的磁通密度波形導致電機損耗特別是鐵損的計算非常困難。電機的損耗又會引起電機的溫升,因此高性能的sr電機的熱分析也成為目前的研究熱點。
