Compact, Efficient Electric Propulsion Motor for Multiple Applications
Agency / Branch:
DOD / ARMY
Electrodynmaics Associates, Inc. has under development a 50 kW 10000 RPM electric propulsion motor and controller. The Phase I activity is in progress, and the electromagnetic analysis, structural analysis as well as thermal analysis of the motor is completed indicating satisfactory operation at the rated load continuously, and 5 minute operation at 100 kW load. In addition 350% of the nominal torque is available at speeds to 2000 RPM. The power density is 14 kW/liter and the torque density is 51 Nm/liter. The motor design utilizes innovative concepts that allow reduced winding end turn length, and high magnetic flux density in the air gap. The controller uses innovative concepts needing low current draw during transient operations. During Phase II, two motors and controllers will be fabricated, the controller will be fine tuned, and the complete set will be demonstrated for operation under steady state and transient loads. Performance analysis including, efficiency mesurements, and transient response will be done. The units will be supplied to US Army for further tests in Warren, and at the SIL facility.
