永磁同步电机性能分析的一种图形化方法

摘要

针对永磁同步电机( PMSM)性能分析不便的问题,提出了一种通过定子电流矢量轨迹分析PMSM性能的方法,即基于PMSM的数学模型,编写MATLAB程序,计算电机的各项性能下的参数,从而提高分析的效率.同时,以图形方式给出定子电流矢量轨迹,可让人很直观地了解电机的性能.%A new way to analysis performance of permanent magnetic synchronous motor ( PMSM ) through stator current vector track was introduced. Parameters under different performance of PMSM can be worked out simultaneously through a MATLAB program, which was programmed based on the math model of PMSM. Performance could be depicted intuitively through stator current vector track present in a picture. The effectiveness of this way was verified by truth.
