Influence of Leading Design Parameters on the Performance of a T-Shaped Permanent Magnet Tubular Linear Motor

Abstract:

This paper deduces from Finite-Element Analysis (FEA), the influence of leading design parameters on the performance of a novel T-shaped permanent magnet (PM), quasi-Halbach magnetized tubular linear motor. The proposed motor is designed and developed for small reciprocating applications. In order to obtain the maximum power density, a two-dimensional Finite-Element model is developed to investigate the performance of the proposed machine. The proposed T-shaped PM structure has a higher power density as compared to the conventional rectangular-shaped PM structure. The losses of the motor, such as copper loss and iron loss, as well as the efficiency, are established as functions of a set of motor leading design parameters. It is shown that the developed motor produce satisfactory output power, around 85 W, which is enough to operate the direct-drive reciprocating compressor of a household refrigerator.
