Abstract

Single-phase induction motors are widely used in industry and the domestic sector. Their production in the world reaches several million pieces. In this regard, the share of electric energy consumption, despite the fact that their unit power is 0.5-1.5 kW, is up to 10% of the total power consumption by AC motors. Therefore, obtaining high rates, such as efficiency and power factor, is an urgent task in their design. The article studies the influence of magnetic flux, which is created by the main winding of the motor, on the nature of the field in the air gap. Its energy performance ultimately depends on the degree of ellipticity of the circular field in the air gap of a single-phase induction motor. In the ideal case, the field should have a circular shape, but this indicator is practically impossible to achieve. As a result, a technique is proposed for obtaining a field that is as close to circular as possible by designing the main motor winding. This technique has been successfully tested at an industrial enterprise when developing a series of single-phase induction motors.

基于最大效率的单相异步电动机绕组参数优化

单相感应电动机广泛应用于工业和民用领域。它们在世界上的产量达到数百万件。在这方面，尽管它们的单位功率为0.5-1.5 kW，但电能消耗的份额高达交流电机总功耗的10%。因此，获得较高的效率和功率因数是其设计中的一个紧迫任务。本文研究了电动机主绕组产生的磁通对气隙内磁场性质的影响。其能量性能最终取决于单相感应电动机气隙内圆形磁场的椭圆度。在理想的情况下，场应该是圆形的，但这个指标实际上是不可能实现的。因此，提出了一种通过设计主电机绕组来获得尽可能接近圆形磁场的技术。该技术已在某工业企业研制系列单相感应电动机时进行了成功的试验。
