Enhanced Motor Performance via Two-Phase Thermal Management

Thermal management presents a significant constraint on the achievable efficiency and power density of MW-scale electric motors for aircraft propulsion. High temperatures within the windings limit the maximum power density, reduce the lifetime of the winding insulation, and increase electrical losses lowering efficiency. Innovative thermal management strategies can significantly enhance the performance of motors for electrified aircraft propulsion.In this SBIR program, Advanced Cooling Technologies, Inc. will develop an innovative two-phase thermal transport system for high power electric motors that will augment traditional cooling solutions by efficiently extracting heat from difficult to cool areas. The two-phase thermal transport system will be fully passive, lightweight and scalable. The proposed technologies will reduce the operating temperature of the motor windings allowing for increased power density and efficiency.
