Abstract

A hybrid excited linear flux switching permanent magnet motor (HLFSPMM) is a possible solution for developing a rare-earth-magnet-free electric motor with high force density. We designed an HLFSPMM that uses a ferrite magnet in place of a rare earth magnet. A suitable mover slot and stator pole number combination was selected in the initial design stage to achieve the desired performance capability. Structural refinements using design sensitivity analysis (DSA) based on the finite element method (FEM) were performed to enhance the machine performance. Simulation results have been validated by experimental measurements.
