End Edge Characteristics of the Stationary Discontinuous Armature PM-LSM by Installing the Double-Auxiliary Teeth
The stationary discontinuous armatures that are used in permanent magnet linear synchronous motors (PMLSMs) have been proposed as a driving source for transportation systems.However,the stationary discontinuous armature PMLSM contains the end edges which always exist as a result of the discontinuous arrangement of the armature.For this reason,the high alteration of the end edge cogging force produced between the armature’s core and the mover’s permanent magnet when a mover passes the boundary between the armature’s installation part and non-installation part has been indicated as a problem.Therefore,we have examined the end edge cogging force by installing the double-auxiliary teeth at the end edge of the armature in order to minimize the end edge cogging force generated when the armature is arranged discontinuously.This paper presents the results of 2-D numerical analysis by FEM of the cogging force exerted by the end edge.
