Characteristics analysis of PM linear synchronous motor with non-uniform air-gap
This paper investigates the performance of a iron-core type 16-pole 15-slot Permanent Magnet Linear Synchronous Motor (PMLSM) for ropeless elevator applications. Considering the existing of the non-uniform air-gap in the long stoke running, the finite element models for double-side PMLSM is established to calculate and compare the electromagnetic performance such as magnetic field, Electromotive Force(EMF), thrust force, normal force and detent force with the uniform and non-uniform air-gap.
