The efficiency of three-phase induction motors is larger than that of single-phase induction motors with the same output, because the spatial higher harmonics of magnetomotive force in the air-gap in the three-phase motor is less than those in the single-phase motor. However, as the three-phase motor requires a three-phase power supply, the single-phase motors are used in small-power applications for offices and houses, in which the three-phase distribution line is not supplied. Therefore, if we can manufacture the single-phase motor with a three-phase rotating field in the stator, it is very useful for energy conservation.The author has been proposed a three-phase parametric motor excited by a single-phase power supply. In this research, the author has studied the stabilization of parametric oscillation of the motor in order to improve the characteristics of the motor.The following results were obtained:(1)Forming the inner and outer ring of a stator in an asymmetric shape is highly effective in stabilizing the parametric oscillation and in improving the motor characteristics like output and efficiency.(2)The asymmetric shape of the outer ring of a stator does not influence on the stability of the parametric oscillation.(3)Using the magnetic anisotropic material for the stator is also effective in stabilizing the parametric oscillation and in improving the motor characteristics.(4)Using the magnetic anisotropic material for the stator and forming it in an asymmetric shape deteriorates the stability of parametric oscillation and the output power of the motor.(5)The operation of the motor is expressed by the nonlinear simultaneous differential equation, which is one of the Mathieu equations. A condition of generation of three-phase voltages was found by the qualitative analysis of the motor based on the equation.

在相同的输出功率下，三相异步电动机的效率比单相异步电动机的效率高，这是因为三相异步电动机气隙中磁动势的空间高次谐波比单相异步电动机少。然而，由于三相电动机需要三相电源，因此单相电动机用于办公室和住宅的小功率应用中，其中不提供三相配电线。因此，如果能够制造出定子中具有三相旋转磁场的单相电机，对于节能是非常有用的。作者提出了一种单相电源激励的三相参量电机。为了改善电动机的特性，本研究对电动机的参数振荡的稳定化进行了研究，得到了以下结果：（1）定子的内外环形成为非对称形状，在稳定参数振荡和改善输出、效率等电动机特性方面非常有效。（2）定子外环的非对称形状不影响参数振荡的稳定性。（3）将磁各向异性材料用于定子在稳定参数振荡和改善电动机特性方面也是有效的。（4）将磁各向异性材料用于定子并将其形成为非对称形状会使电动机的参数振荡的稳定性和输出功率劣化。（5）电动机的运行由非线性联立微分方程表示，该方程是Mathieu方程之一。通过对电动机的定性分析，找到了三相电压产生的条件。
