交流电机变频调速控制特性曲线的选择

Selection of Characteristic Curves based on Variable Frequency Speed Control of AC Electric Machines

随着交流电机变频调速技术的广泛应用 ,通用变频器以其强大的功能而用于各种交流电机调速。本文主要分析变频器最基本的功能 ,即各种类型的变频特性曲线表征的物理意义 。

A wide application of adjustable speed technology by variable frequency has been seen. The general inverters with powerful functions are used for all kinds of variable speed of alternating current(AC) electric machines. The fundamental functions which express the essential characteristticis of variable frequency control curves are mainly analyzed in this paper. Finally, the method of selecting characteristic curves was given with a real demonstration.
