针对单相异步电机的特点,提出了一种新型的单相异步电机结构——助磁式单相异步电机,它能有效地减小气隙磁场椭圆度,提高电机运行性能。在理论上分析了助磁式单相异步电机的基本原理,建立了电机模型,进行了计算机仿真,并结合试验数据,将助磁式单相异步电机与普通电容起动单相异步电机进行比较,从而在理论和实践两个方面给予了很好地证明。

According to the characteristics of single-phase asynchronous motor, a new type of single-phase asynchronous motorsingle-phese asynchronous motor with optimized magnetism was introduced. It can reduce the degree of ellipse of the magnetic field of air gap, and increase the efficiency of motor. The basic principle of single-phase asynchronous motor with optimized magnetism was analyzed, the single-phase asynchronous motor with optimized magnetism and capacitance startup single-phase asynchronous motor in aspects of motor＇s model were compared, characteristics by simulation in computer and experimental data respectively were run. Thereby, the theory was improved.
