Flux intensifying interior permanent magnet synchronous machine (FI-IPMSM) was designed to improve the characteristic of conventional permanent magnet machine, especially, in field weakening region. Increasing a saliency ratio is the main method to achieve this target which leads to increasing reluctance torque than magnetic torque and so improving the machine performance. In this paper, the characteristics of FI-IPMSM are investigated. The effect of PM material, PM width, PM thickness, flux barriers width, and iron bridge thickness on the machine parameters is studied. Machine inductances, no-load and full-load characteristics are analyzed. A comparison is carried out between the FI-IPMSM and conventional IPMSM to evaluate the improvement in machine performance. Two-dimensional time-steeping finite element method (FEM) is employed in analysis of the FI-IPMSM and conventional IPMSM.
