摘要
考虑空调压缩机对电机的要求,对各种型式永磁同步电动机的变频调速问题进行了探讨,同时介绍了利用三相桥式逆变器实现永磁同步电动机变频调速的控制方法,并运用仿真技术验证了系统在变频范围内的运行特性。
This paper investigates some concerns in the variable frequency operation of single-phase and three-phase permanent-magnet synchronous motor considering the requests of electrical machine used in air-condition compressor,introduces the control method which adopts three-phase inverters to adjust speed of the motor, and proves the performance of system in the adjustable frequency ranges by simulation technology.
