Consideration of linear synchronous motor characteristic in curved part

Linear synchronous motor (LSM) is used in industrial machines for positioning and conveying equipment. A variety of layout lines has been suggested to be highly expected to raise productivity. Flexible layout of the track including curved part is an advantage of the application. For example, the track shaped production lines of circular system is used to reduce the waste time that occurs during return and stop of the carrier including the mover. Furthermore, this paper discusses design considerations and verification results of Linear and Curvilinear Synchronous Motor (LCSM) which is a linear motor driving in a straight part and a curved part. It was confirmed that the ratio of the thrust reduction by FEM analysis and prototype evaluation are mostly the same as the result considering by skew factor. Moreover, Multi Carrier Module (MCM) demonstrated drive of LCSM seamlessly.
