摘要
介绍两种自控式电动机驱动系统(永磁无刷直流电动机系统和开关磁阻电动机系统)的共性、速度闭环微机控制系统的实现及逆变器控制方法等。该系统在一种新研制的医疗器械上试运行表明,电机效率高、调速范围宽而平稳、噪声小,效果令人满意。
General characters between two kinds of auto drive system (brushless dc motor and switched reluctance motor),realization of closed-loop speed control system with microcomputor and control types of inverter etc.are introduced.Experimental result shows that the motor has high efficiency,wide ad- justable-speed and operating smoothly,low noise,it meets our requirement.
