Abstract
Running characteristics of permanent magnet linear synchronous motor(PMLSM) which is usually used in the system requiring the high acceleration and the accurate position precision are investigated. Also, employment of partial excitation of primary current according to the mover position for the efficient motor drive, and its influence on the EMF and thrust force ripple are considered in detail. Furthermore, capability of PMLSM manifesting the speed-force feasibility under the running condition will be followed.
