Design and Development of Permanent Magnet Linear Synchronous Motor (PMLSM)

摘要

Background/Objectives: A steady increase in industrial applications has secured an important place for linear electric motors. This paper deals with the design, development and electromagnetic analysis of PMLSM for conveyor and transit applications. Methods/Statistical Analysis: PMLSM for the stated application has been designed and modelled. Electromagnetic analysis of the model has been done using 2D Finite Element Method (2D-FEM) to predict the performance of PMLSM. Findings: Electromagnetic characteristics of PMLSM have been investigated and results have been presented. Results show the upper hand of PMLSM over Linear Induction Motor (LIM) in terms of normal force to propulsion force ratio which is one of the primary concerns while choosing a linear drive for transit and conveyor applications after manufacturing costs. Applications: Some typical industrial applications of linear motors like PMLSM include electronic assembly, baggage handling, machine tools, PCB assembly/drilling, robotics, conveyors, elevators etc. Keywords: Cogging Force, Finite Element Analysis (FEA), Linear Motor, Permanent Magnet Linear Synchronous Motor (PMLSM)
