Abstract

A tubular flux-switching permanent-magnet linear machine (PMLM) is proposed and designed for free-piston energy converter. The influences of several main structure parameters on the machine performances are investigated. The power, power density and efficiency are improved by optimizing the structure parameters. Further, characteristic of the detent force is studied and the detent force is reduced by choosing proper combinations of the structure parameters. Finally, with poor heat dissipating condition considered, thermal field distribution of the proposed machine is evaluated by 3D finite element analysis (FEA), which ensures safe operation of the machine.
