Abstract

This paper presents an approach for enhancing the thrust force of a tubular transverse flux permanent magnet linear machine (TFPMLM) that has been developed for electromagnetic applications. It is shown that, by introducing auxiliary cores to suppress the leakage flux, the thrust force of the tubular TFPMLM can be significantly enhanced, by ~ 130%, under the same volumetric constraints. The effectiveness of the proposed technique is validated by extensive three-dimensional finite element computations.
