Title: Phase I STTR Final Report

Abstract

In this Phase I STTR project, the potential technical and economic barriers and solutions to apply VF machines to the vehicle traction application will be investigated. Experimental methods will be used to understand the demagnetization and magnetization behavior of various grades of AlNiCo magnets under a wide range of operating temperature, how repeated demagnetization and magnetization process will affect reliability, how to implement online demagnetization and magnetization of the VF machine without interrupting the vehicle operation. A100-kW VF machine will be designed that uses multiple grades of AlNiCo magnets so both high power density and easy control of the demagnetization and magnetization of magnets can be achieved. Additionally, a silicon-carbide based power converter will be designed for the proposed VF machine. Finally, a cost analysis for a VF machine and drive system will be developed, a reliable supplier and manufacturer chain will be assembled to prepare for the 100-kW VF machine prototype construction in Phase II, and the proposed technology and research results will be disseminated to automotive OEMs.
