单绕组异步电动机运行特性的分析计算

Performance Analysis and Calculation of Single-winding Induction Motors

导出了单绕组异步电动机功率因数、效率等一系列运行特性的计算公式,且用等效电路的参数来表示运行特性与设计参数的关系和变化趋势。同时还导出单绕组异步电动机与电容运转电动机的关系式,由此可直接从电容运转异步电动机的设计参数得到单绕组异步电动机的设计参数和运行特性,而不必另行计算。

A series of calculation formula for the power factor and efficiency of the single-winding induction motor was introduced in the form of expession by the parameter of equivalent circuit, which predicated the performance and designed data. The parameter relationship of calculation formula between that of single-winding and capacitor- run induction motor was presented, capable of achieving the design data and operational characteristic of the single-winding induction motor driectly from those of the capacitor-run inductoin motor without repeated calculation.
