We have been developing an electromagnetic linear actuator for an artificial muscle which has long stroke, quick response and large thrust using interior permanent magnets effectively. In this paper, we propose a novel small size cylindrical linear vernier motor with axially magnetized magnets. This actuator has a simple structure whose mover is composed of sets of a ring magnet between iron rings. Axially opposite magnetized magnets are alternatively arranged. The thrust and detent force of the actuator are calculated by the 2-D finite element method. As the results, the thrust of the actuator 12.9N under 1A effective current is achieved with detent force ±1.1N.
