Advanced Materials Processing for Ultra-Efficient Power Systems

The Advanced Materials Processing of Ultra Efficient Power Systems program team is using a collaborative approach to develop, demonstrate and deploy applications of copper and copper based alloys for more efficient and effective use in defense system applications, by leveraging copper's unique physical and mechanical properties. This includes researching and developing tools to provide improved capability in predicting motor performance in the design optimization stage of copper die cast motors.

Phase I

This effort is focused on the enhancement of classical electric motor analysis methods, as well as development and utilization of new electromagnetic, finite and thermal modeling techniques.

Phase II

Advanced modeling and analysis techniques for induction motors with copper die cast rotors developed in Phase I will be validated in Phase II. Long term Phase II efforts will target the development of robust cast copper rotor design criteria suitable for high speed aerospace rotors. Efforts will focus on validating the models by comparison with laboratory test results.

Phase III

Based on the results of Phase II, the program team will develop new motor-based power systems with improved efficiency and performance over legacy systems.

Goal

The goal of this development is to implement a strategy to deploy the developed copper die cast technologies throughout the defense supply chain.
