Mover Design and Performance Analysis of Linear Synchronous Reluctance Motor with Multi-flux Barrier

Abstract

A Synchronous reluctance motor has many advantages because it has no permanent magnet, such as low back emf in a high speed operation, keeping performance in a high temperature environment and so on. Therefore, many rotor constructions are studied and developed. The rotor with multi-flux barrier structure has the merit of its easy construction and high performances.The linear synchronous reluctance motor have been developed. It is necessary to improve the performance by the mover design for industrial use, because of its low power factor.In this paper, we propose a novel configuration of mover for linear synchronous reluctance motor, and examine the static characteristics of linear synchronous reluctance motor with reluctance equalization design by using finite element method. From analytical results, it is cleared that the static characteristics of the linear synchronous reluctance motor is greatly improved by the reluctance equalization design at the iron layer in the mover.
