Abstract
A brushless and slotless DC linear motor(LDM)employing a movable set of neodymium-iron-boron type of magnets has high performances in advantages of large thrust per weights and accurate position control. But the Moving Magnet LDM produces thrust ripples owing to mainly end-effects, shape and magnetization of permanent magnets and so on. This paper represents the improvements of thrust ripples using the finite elements methods and phase control topology.
