摘　　要：讨论含有逆序磁场的径向力波对电磁噪声的影响。试验表明,逆序磁场为零与不为零两者声学效应的规律基本相同,微型单相异步电动机的电磁噪声与磁场椭圓度近似成正比。The thesis discusses the effect on electric-magnetic noise by radial force wave which partly produced by negative phase-sequence. Experiment shows that the acoustic effects are approximately idential when the negative phase-sequence is zero and not. The electric-magnetic noise of single-phase induction micromotor is approximate direct ratio to the ellipse degree of magnetic field.
