Abstract
Permanent magnet linear synchronous motors (PMLSMs) have been widely used as the driving source to satisfy requirements such as the speeding up of transportation systems. PMLSM is expected for the higher thrust and higher speed, thus, the thrust force characteristic is one of investigative hot spots to PMLSM. This paper presents the electromagnetic thrust force characteristics in different conditions including: frequency, length of air-gap, U / f and number of poles. The analysis results provide a foundation for the optimum design of PMLSM.
