高效变频空调压缩机用永磁同步电机研究

Study of Permanent Magnet Synchronous Motor Used in Compressor for High-Efficient Inverter Air Conditioner

拟采用磁路解法确认家用变频空调器的压缩机用调速永磁同步电机的关键尺寸,再利用有限元分析方法精确计算电机的各项性能。对比电动机性能的理论设计值与实际测试值的差异,同时对比了变频压缩机和对应空调器的性能,通过实际测试说明该方法的准确性与可行性。

Critical dimension of permanent magnet synchronous motor used in compressor for the home inverter air conditioner was confirmed by magnetic circuit analysis method, and motor performances were calculated accurately by finite element method. Comparing the difference between theoretical designed value and testing value of motor performances, compared the performance of inverter compressor and the corresponding air conditioner, the actual test showed that this method was accurate and feasible.
