Abstract

The slot less permanent-magnet linear synchronous motors (PMLSM) have been developed for factory automation, transportation applications, wafer steppers, conveyance system, and so on [Seok-Myeong Jang, Sung-Ho Lee, 2002]. The current analysis and design are treated in air- cored PMLSM. This paper presents a design and analysis solutions for the general class of iron-cored permanent magnet linear synchronous motor (PMLSM). In our design and analysis, rotor consisting of permanent magnets and slot less iron-cored coil stator are treated in a uniform way via the magnetic vector potential [D. L. Trumper, et al., 1996]. For one such motor structure we give analytical formulas for its magnetic field, back electromotive force (EMF) and trust force. We also provide comparisons of three types in Halbach, vertical, and horizontal magnet array.
