摘要
介绍了变频空调与永磁电动机的理论基础,对无位置传感器技术、低速起动技术作了详尽的论述,并从电路硬件结构和实现方法入手,着重分析了在变频空调器压缩机中采用永磁电动机转速控制的策略。
Presents the basic theories of the variable-frequency air conditioners and permanent magnet motors. Discusses the sensorless and the low-speed starting techniques in detail. According to the hardware structure and the implement method, analyses the policy of speed-control on the permanent magnet motor applied to the variable-frequency air conditioner compressor.
