摘要
本文介绍了感应式直线电动机的控制方式,即采用瞬时电流跟踪PWM变频技术,控制感应式直线电动机的推力和移动速度。实验证明该方式对于减小直线电动机推力脉动,降低噪音是有效的。
This paper studies the controlling mode of linearmotor. PWM inverter with instantaneous current follow-up is used to control the thrust and change the moving velocity of induction linear moter. The experiment proves that the mode is effective to reduce the puls ation and the noise of linear motor.
