Parameter Optimization of a Tubular Linear Type Reluctance Motor for High Thrust Force

Abstract

In this paper, the parameters of a linear type reluctance motor was verified by varying the motor parameters; i.e. (a) air gap thickness and (b) number of winding turns of a 3-phase Tubular Linear Reluctance Motor (TLRM). The aim is to optimize the electromagnetic thrust force. At first, a three-dimension TLRM structure is designed using ANSYS Maxwell 3D software Ver. 17.2. Next, the effects of the varying parameters are evaluated using Finite Element Method (FEM) analysis. The obtained results show that the variation of the air gaps and the number of winding turns greatly influence the electromagnetic thrust force. It is found that the maximum thrust force of the design TLRM is 370.3mN at 0.5mm air gap thickness and 300 numbers of winding turns.
