Abstract :
This paper presents a new partial excitation control method of the moving magnet linear synchronous motor and proposes an implementation and a control method for a dual mover linear motor. The problem of the conventional partial excitation circuit is clarified and a new partial excitation control method is proposed, which is external control by a main control board. Based on this partial excitation control method, a novel control method for a dual mover moving magnet type linear motor is proposed. The validity and performance of the proposed partial excitation control method for the linear motor is verified by experimental results. These experimental results reveal excellent position control capability such as less than 10 /spl mu/m position error within 10 msec after position command, while both movers are controlled independently.
