Innovative Stator Thermal Management to Improve High-Torque Motor

With the advent of high-power, solid-state converters, variable speed motor and generators are finding wide applications in both DoD and commercial applications. At the same time, advanced system requirements put more demand on motor torque and power output. This proposal based on application of high-conductivity encapsulated graphite in critical motor components promises to increase the torque and power of existing designs by 25% with minimal weight and no external volume impact. The Phase I proposal will demonstrate potential payoff by tests on representative components.
