摘　　要：单相异步电机的脉振磁场可以分成两个转向相反的旋转磁场,并由此可以继续分析转子绕组的受力情况,但是,不能将单相绕组的两极与这两旋转磁场各自对应,并进而做出各种错误的猜想。异步电机旋转磁场的产生必须满足其最基本的条件,只有正确理解了电机的电磁关系才能把握电机的工作原理及工作特性。The pulse-vibrating magnetic field of the single-phase asynchronous motor can be divided by two rotary magnetic field with different directions, and can go on analyzing the pressure of rotor winding. But we the two poles of the single-phase asynchronous motor can't be corresponded to these two magnetic fields,which giving all kinds of false imaginations. The production of the asynchronous motor rotary magnetic field must meet its basic requirements. Only when you understand the magnetic relation ship of the motors correctly,can you master the principles and characteristics of the motor.
