ABSTRACT: The problem in improving the positioning precision of a permanent
magnet linear synchronous motor (LSM) is the large detent force caused
by the permanent magnet. The detent force is thought to arise from the
difference of the position of a permanent magnet end and a tooth
position. If one detent force is independent from the other, we can
reduce the total detent force of the permanent magnet linear synchronous
motor by the arrangement of a permanent magnet end and a tooth. This
paper presents are improvement of the arrangement of the permanent
magnet end of a linear synchronous motor in order to reduce the detent
force by using numerical analysis
