Thrust and Cogging Force Improvement on Inductor Linear Motor
This paper shows a novel design method of MAGNAGAP Linear Motor (MLM) which is a type of inductor linear motor. The MLM has several disadvantages of the shortage of thrust and the increase in cogging force with thrust. First, in order to improve the maximum thrust and the motor constant, the design method proposes optimum armature structure which may ...
