Abstract :
Stationary discontinuous armatures that are used in permanent magnet linear synchronous motors (PM-LSM) have been proposed as a driving source of transportation systems. However, the stationary discontinuous armature PM-LSM contains the outlet edges which always exist as a result of the discontinuous arrangement of the armature. These edges become a problem because the cogging force that they exert influences the controllability of the motor. This paper presents the results of three-dimensional numerical analysis by the finite-element method of the cogging force exerted by the outlet edge
