摘    要:本文对采用三相逆变器供电的单相永磁同步电动机变频起动过程的转矩进行了深入的分析,提出了用于单相永磁同步电动机变频起动分析的简化等值电路,分别用拟稳态法和简化等值电路法计算了单相永磁同步电动机变频起动过程中的异步起动转矩,两者计算结果相一致,证明了该简化等值电路法的正确性。根据简化等值电路法推出了变频起动时保证最大异步转矩保持恒定的完全补偿法,用拟稳态法计算了采用完全补偿法变频起动时的异步转矩和平均转矩,验证了完全补偿法的正确性。

关 键 词:单相永磁同步电动机  变频起动  转矩  恒定最大异步转矩  完全补偿法

Abstract:This paper analyzes the starting torques of the single-phase permanent-magnet synchronous motor (SPPM) fed by three-phase inverter, and presents the simplified equivalent circuit for the analysis of variable frequency starting process. Using method of quasi-steady state and the simplified equivalent circuit repspectively, it calculates the asynchronous starting torque of single - phase PMSM during variable frequency starting. The two results are consistent, so it proves that the simplified equivalent circuit method is accuracy. It deduces the voltage compensation method, calculates the asynchronous torque and average torque during the variable frequency starting process, and verifies the validity of the method.
Keywords:single-phase permanent-magnet synchronous motor  variable frequency startingprocess  torque analysis  constant maximum asynchronous torque  voltage compensation method
