摘要
交流高压电动机的调速比较成熟的方式有变频调速和串级调速 ,内反馈串级调速电机的设计也是个较新的技术 ,本文分析内反馈串级调速的原理、设计过程及难点 ,这一技术用在风机、水泵等的调速运行中 。
Frequency conversion and cascade speed adjusting can be used for high voltage a.c. motor, and design of internal feedback cascade speed adjusting motor is also a new technology. The principle and the design process and difficulty of internal feedback cascade speed adjusting are analyzed. The technology can be used in speed adjusting operation of fan and water pump, and has more remarkable energy saving effect than resistance in series speed adjusting.
