220kW 交流无换向器电机调速拖动系统

220kv AC Commutatorless Motor Speed-Control Drive system

交流无换向器电机拖动系统由平波电抗器、频率变换器（交交变频器）、无换向器电动机及控制器四大部分组成。给出了２２０ｋＷ拖动系统的电动机、电抗器、频率变换器的结构形式及主要参数，介绍了调速系统的构成和工作原理，导出了调速系统的静态结构图和动态结构图。用工业应用系统的实测的速度、电流曲线来说明了系统的运行性能。

A AC commutatorless motor drive system usually consists of four main parts:filter reactor,frequency converter,commutatorless motor and its controller A 220kW drive system has been well applied in industry production Structure forms and main parameters of frequency converter,motor and reactor in the system are given out Then the speed-control system's construction and operating principle are introduced,and its static structure diagram and dynamic structure diagram are deduced Finally,giving the real curves of its speed and cnrrent is to show how the system's operating performance is
