摘要
提出了一种压缩机用稀土永磁(REPM)无刷直流直线电动机(BLDCLM)可逆控制系统。介绍了系统的工作原量、电机末端冲击方法、无位置传感器检测方法、PWM速度反馈方法及其相关电路。分析表明。
This paper presents bi-directional control system based on rare earth permanent magnetic(REPM)brushless DC linear motor (BLDCLM) used in compressors.The principle of the system, the method of the motor ending impact, the position detection under sensorless, and PWM speed feedback control are introduced.The analysis shows the methods can achieve the constant thrust control of motor.
