摘要
通过对90kW电动机控制的改造实践,论述了变频器及软起动器在交流电动机中的应用。结果表明,交流电动机的软启动和变频调速不仅减少了启动电流对电网的冲击,同时还可以实现电动机的节能。
This paper presents the application of frequency converters and soft-starter in motors. A 90kW motor ontroller was modified. The results shows that soft starting and timing of frequency conversion of motor not only reduce the impact of starting current on electric net, but also reduce the electric consumption of motors. [
