Transverse flux type cylindrical linear synchronous motor for large thrust using generic armature cores for rotary machinery

Linear motors have been of great interest in industries. Especially, the permanent magnet linear synchronous motor (PMLSM) has contributed to its popularization in industrial fields. Among technical performance required to PMLSM, large thrust is an important when considering conveyance of heavy materials such as large glass. The authors propose transverse flux type cylindrical linear synchronous motor for large thrust using generic armature cores for rotary machinery. In this paper, the structure and operational principle of the proposed motor are described. Also, thrust is both theoretically and numerically analyzed by magnetic circuit method and field calculation using the Finite Element Method (FEM).
