摘要
主要分析了采用工频电源和变频电源供电的笼型异步电动机在起动、运行、制动、停止等方面的特点以及控制环节上的区别。同时对变频器的性能进行了分析,提出了变频调速异步电动机在设计与使用上,如何能满足变频调速系统的要求。
This paper chiefly analyzes the differences on control links between squirrel- cage induction motors fed by mains frequency power supply and various-frequency power sup- ply, and describes their characteristics in aspects of starting, operation, braking and shutting down. Based on performance analysis of frequency inverter, this paper puts forward how to meet the requirements of variable-frequency adjustable-speed system in aspects of design and use of variable-frequency adjustable-speed induction motor.
