Drive Characteristics of High Efficiency Hybrid Excitation Motor for Automobiles

Abstract

This paper presents design studies on a hybrid excitation motor (HEM) and experimental drive characteristics of the HEM for hybrid electric vehicle drive applications. Taking an IPMSM installed on PRIUS'2010 as the object of a comparison, the HEM is designed by means of trial and error using 3-dimensional finite element analysis (3D-FEA) and built as a test machine. With comparisons between the measured and the 3D-FEA-computed drive performances of the test motor, it is verified that the proposed HEM is a viable candidate as high efficiency motor for the target application.
