串激通用电机性能分析的一种简明方法(英文)

A Concise Method of Characteristic Analysis for Sciences Universal Machine

串激通用电机能够在直流电源或交流电源上使用,它的运行特性的分析比较复杂.本文介绍一种较好的简明分析方法,即利用这种电机的相量图先作出一个“圆图”,再利用该圆图中的相关线段和角度之间的关系,得出电机的运行特性,即电机的电流、转矩、功率、转速等随负载变化的情况.

The series universal machine could be operated on d. c. or a.c. source. It was relatively complicated to analyze its operating characteristic. A good concise analysis method was introduced. By using the phase diagram to form a' circle diagram' and the relationship between the pertinent line segments and the angles,its operating characteristic was got. Namely, its operating characteristic was the variation of current, torque, power, speed, etc. as the load was varied.
