Design Validation of a Moving-Magnet Tubular Linear Permanent Magnet Motor with a Trapezoidal Permanent Magnet Shape

Abstract:

This paper presents the design validation and optimization of a moving-magnet tubular linear permanent magnet motor (TLPMM) with a trapezoidal permanent magnets shape. The design optimization was implemented by two-dimensional Finite-Element Analysis (2-D FEA) and the validation has been established by using Matlab M-file. The proposed motor has been designed to produce 85 W output power which is enough to operate the linear reciprocating compressor of a household refrigerator system. The purpose of optimization is to achieve maximum efficiency and minimum losses, where the angle of PMs (β) and split-ratio (R_m/R_e) after optimization the motor produce the highest efficiency of 93.8 %.
