摘　　要：在矿山、隧道、冶金和轻工业中,有大量的机械,如风机,水泵,电梯,搅拌机和压缩机。这些机械常用的交流电机驱动,功率超过几百千瓦,甚至几千瓦,它的功耗非常大,而且绝大多数只占额定功率的百分之五十到百分之七十,甚至更低。交流电动机的多模式启动和平滑速度的问题也是使实际生产困惑的一个重要问题。在变频器系统结构和工作原理方面,本文深入讨论了变频器在电机控制系统中的综合应用及其技术经济优势。In the mines, tunnels, metallurgy and light industries, there are a lot of machines, such as fans, pumps, elevators, mixers and compressors. These mechanical commonly used ac motor drive, power more than a few hundred kilowatts, or even a few kilowatts, its power consumption is very big, and the vast majority of only accounts for fifty percent to seventy percent of rated power, even lower. The problem of multi-mode start-up and smooth speed of ac motor is also an important problem in practical production confusion. In terms of the structure and principle of the frequency converter system, this paper discusses the integrated application of inverter in the system of motor control and its technical and economic advantages.
