Analysis and Design optimization of Ironless Linear Permanent Magnet Synchronous Motors with Non-overlapping Concentrated Windings for Ultra-precision Positioning System

摘要：

　　This paper presents the electromagnetic design of Ironless permanent magnet linear synchronous motor with nonoverlapping 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.
