基于无因次法三相感应电机机械特性的研究

Study on Mechanical Characteristics of Induction Motor Based on Dimensionless Performance

采用无因次系数法,按电机产品目录给出的额定点、临界点和起动点的参数,总结出了感应电机的通用机械特性实用方程。该方程绘制的机械特性曲线与试验所得曲线基本一致,为感应电机的起动、制动的动态分析与计算以及T-S曲线的绘制,提供了一个简便而实用的数学模型。

Mechanical properties equation is obtained from the parameters given by the electrical products catalog including rated point, critical point and starting point with dimensionless method. The curve from this equation is very anastomosis to the one drawn from the experimental data. The opinion provides a simple and practical model for the analysis of starting and braking of induction motor and T-S curve drawing.
