Abstract

This paper presents the concurrent design of interior permanent magnet (IPM) machines for self-sensing and power conversion. Simulations with finite-element analysis are mainly used to gain insight of magnetic behavior and flux characteristics in the evaluated machines. q-axis flux barriers are used in the concurrent rotor design due to their effective reduction in saturation effect from load current. A saliency characteristic with L_d >; L_q obtained, and benefits in self-sensing and power conversion are found in the concurrent design of IPM machines. Design effects of different rotor structure parts are also evaluated.
