Advances in electric motors are needed to meet joint program goals for electric and hybrid electric vehicle power trains. However, conventional methods for increasing motor power density lead to difficult cooling requirements and increased cost. In addition, conventional cost-reduction methods lead to reduced motor performance. This project will develop highly integrated, motor and electronic modules that will allow for the optimization of electromagnetic, thermal, structural and control design parameters. This systems approach will provide required motor performance while minimizing cost through high-volume production processes. Phase I will begin with experiments and research for reducing the size, weight, and cost of motor/electronic modules. Existing computer models for vehicles, motors, and electronics will be expanded to predict system performance as various sub-systems become integrated. Emphasis will be placed on the evaluation of advanced thermal management techniques within the integrated motor modules.
Commercial Applications and Other Benefits as described by the awardee: Affordable, high performance electric motor modules should be provided for vehicles and for industrial and military applications.
