Abstract
The permanent magnet synchronous planar (PMSP) motor is special planar positioning equipment that has received increasing attention in the academic and industrial fields because of its high positioning accuracy. However, PMSP motors require higher current density to achieve large thrust compared with conventional rotating electrical motors. Such a requirement results in great loss and rapid temperature rise. In this study, a thermal resistance network model is proposed to investigate the transient temperature field of PMSP motors. The spreading thermal resistance among coils, iron cores, and the supporter is obtained based on the equivalent thermal circuit method and solved by the variable separation method, which can generate the transient temperature field for the PMSP motors modeling.
