Compact, Efficient Electric Propulsion Motor for Multiple Applications

Hybrid electric propulsion of Army vehicles is beneficial in terms of fuel economy and silent mobility. High torque and high power density PM motors are needed for these applications.Electrodynamics proposes innovative concepts to achieve and exceed specified goals in power and torque density, efficiency, and scalability. This proposal explores various configurations including inside rotor, outside rotor, and axial gap. After selecting one of these approaches, proprietary innovative concepts are proposed to substantially increase the power density, torque density, and efficiency. These concepts also include the design of controller to match the motor and provide the ability to extend the operating speed range to cover operation from standstill to 10000 RPM. Sensorless design incorporated within software based control using a DSP is proposed. A team of experts in electromagentics, control, software, structural, thermal, and dynamic design of the motor and controller will address all the design issues during Phase I and Phase I Option to be ready to produce demonstrable hardware during Phase II. Military and commercial applications for the product are proposed.
