Optimal design of semi-arch auxiliary teeth of stationary discontinuous armature PMLSM with concentrated winding using design of experiment

Abstract

Although Permanent Magnet Linear Synchronous Motor enables high-speed and high thrust compared to rotary machine, its application to the long-distance transportation system has been delayed due to high installation costs. Thus, by proposing stationary discontinuous armature system that installs armature only at the part accelerating and decelerating mover, we improved the problem of installation costs in this paper. Also, we proposed new shape of auxiliary teeth for the armature end edge of this system to reduce the detent force causing noise and vibration of equipment and showed detent force reduction effect which was more improved than existing auxiliary teeth based on optimal design using the design of experiment.
