摘要
推导了衡量电机气隙磁场优劣的磁势序比的通用公式,分析了磁势序比值的变化对电机性能的影响,提出了不满足理想约束条件下单相异步电机形成圆形磁场的条件,为设计空间非正交两绕组单相电机提供了理论依据。
The general formula for measuring the magnetizing force ratio is derived,and the effect of the ratio on the performance of the motor is analysed based on the formula.The condition forming circular rotating field while a single-phase induction motor doesn't satisfy the ideal constraints is presented,which provides theoretical basis for designing single-phase motor with two non-vertical windings.
