High-Torque Density Design of Small Motors for Automotive Applications with Double Axial-Air-Gap Structures

This paper describes the results of studies on higher torque density automotive auxiliary motors based electromagnetic field analysis. Dual stator axial-gap PM achieve than radial-gap in a flat motor shape. Therefore, an was designed design policy different from that past to reduce its volume by half for applications and experimentally evaluated using prototype motor. In order improve density, double structure adopted wide generation areas optimally designed, reducing 44% compared with existing model. It
