摘　　要：开关磁阻电机由于结构简单、坚固等优点而得到广泛的应用,但是显著振动和噪声的问题在一定程度上限制了开关磁阻电机的应用,针对电机实际运行过程中存在的转子偏心现象,分析了不同线圈连接方式下,转子偏心对气隙磁场的影响,建立了开关磁阻电机转子偏心的有限元瞬态分析模型,研究了线圈连接方式对瞬态的单边磁拉力,结果表明:当线圈并联时产生的单边磁拉力要小于线圈串联时产生的单边磁拉力.采用全并联的线圈连接方式,将有利于减小电机运行时的振动噪声.Switched reluctance machine （SRM） possesses many advantages in different occasion such as simple structure and high efficiency. However, distinct vibration and acoustic noise restrict its application. Because of eccentric rotor of SRM, asymmetrical airgap flux distributions and unbalanced magnetic force of windings will be produced under different winding connection methods, which will deteriorate vibration and acoustic noise of SRM. A transient finite element model （FEM） of SRM with eccentric rotor was established. The results show that the unbalanced magnetic force of the parallel connection winding mode is less than that of series connection winding mode. The full-paralleled windings connection can reduce vibration and acoustic noise of SRM evidently.
