摘要:
从产生根源出发,对永磁同步电动机空载铁耗进行细致分类。在此基础上,利用有限元法和Bertotti 铁耗计算模型,以一台5 kW、3 000 r /min 永磁同步电机为例,对正弦波供电永磁同步电动机的空载铁耗分布特性进行分析计算,得到基本铁耗与空载杂散损耗的比例关系以及不同因素
所引起的空载杂散损耗分布规律。进而,研究了变频器供电空载电流时间谐波引起的谐波损耗,分析了不同极槽配合对变频器供电永磁同步电机的谐波损耗影响规律。最后,通过多台样机的空载铁耗试验,验证了计算的正确性。
Abstract:
The no-load iron losses of permanent magnet synchronous motors ( PMSMs) were classified in detail on the basis of its origin. The finite element method and the Bertotti’s iron loss model were adopted to calculate the iron losses of PMSM. The distribution characteristics of no-load iron losses were calculated in detail and analyzed by taking a 5 kW,3 000 r /min PMSM as an example. The proportional relationship between the basic iron loss and the no-load stray loss were obtained,and the distribution regularities of the
no-load stray loss under different factors were also gained. Harmonic losses produced in PMSM by current harmonics generated by the frequency converter were studied. Without changing the basic parameters of the motor, the harmonic losses in PMSMs were analyzed under different pole and slot combinations. Finally, through the no-load iron loss test of several prototype motors, the results verify the feasibility of the calculation method.
