VVVF控制变频调速减小电机容量对策研究

Reseach on Minishing Electromotor's Capacity by Frenquency Conversing and Timing with the Control of VVVF

本文分析了VVVF控制变频调速系统电动机容许输出特性,各类负载的负载特性及电动机与负载的配合情况,得出最小电机容量的最佳配合模式,提出了各种负载情况下减小电动机容量的措施。

This paper analyses the characteristic of electormotor's faculative output, the load's characteristic of each one and the circumstances of electromotor and load's cooperation, then educes the best cooperation mode.At last,it brings forward some measures about minishing electromotor's capacity under the circumstances of each load.
