Novel compact linear switched reluctance motor with a thin shape and a simple and easily replaceable mover

Abstract

This paper describes a new linear switched reluctance motor (LSRM) with a light and easily replaceable mover. The proposed LSRM has coils at both ends of the stator so as to have a thin shape, which is important for systems with a limited work space. The mover has a simple and thin shape, leading to easy fabrication and space savings. It is made from common materials and is easily recyclable. The flat areas on the surfaces of the mover and stator are used as a slide guide. The prototype LSRM has a thickness of 2.4 mm, and the thickness of the mover is 0.27 mm. The suitable driving signal for the proposed LSRM is determined from the numerical magnetic analysis results. The prototype LSRM shows a velocity higher than 285 mm/s and an acceleration higher than 3 m/s 2. Copyright © 2013 by JSME.
