Abstract

This paper presents the electromagnetic design of Ironless permanent magnet linear synchronous motor with non-overlapping concentrated windings based on the Equivalent Magnetizing Current(EMC) method. For one such motor structure we give analytical formulae for its magnetic field and thrust density and analyze to improve air-gap flux density and thrust density by varying motor design parameters. In order to minimize thrust ripple and improve thrust density, we analyze the superiority of ILPMLSM with Halbach magnet array and fractional-slot concentrated winding. The validity of the proposed technique is confirmed with 2-D Finite Element (FE) analysis.
