空调永磁同步电机轴电压原理及对策

Air conditioning of permanent magnet synchronous motor shaft voltage principle and Countermeasures

随着永磁同步电机在空调系统应用越来越广泛,轴电压的问题不但影响电机本身的噪音及安全稳定性,而且对整个空调系统都会带来危害。本文采用建模的方法对常见空调系统里的永磁同步电机轴电压产生的原理进行理论分析,并结合实例分析轴电压的预防和防治。

With the development of permanent magnet synchronous motor is widely used in air conditioning system, shaft voltage problem not only affects the noise and stability of the motor itself, but also will bring harm to the entire air conditioning system. The principle of the modeling method of permanent magnet synchronous motor shaft voltage of common air conditioning system in the theoretical analysis, combined with the analysis and prevention of shaft voltage examples.
