Advanced Electrical Drivetrains for Propulsion and Traction Applications

The presentation  will cover the following 2 topics:

Very high specific power electric drivetrain for aerospace including the motor, modular integrated drive and thermal management system:
This part of the presentation will provide an overview of an ARPA-E project led by Marquette University as a part of the ASCEND program to develop very high specific power electric drivetrains for hybrid and electric propulsion for aerospace applications. The target is system specific power of 12 kW/kg. The project introduces novelties in the electric motor, electric drive and thermal management system. These include additively-manufactured coils integrated with heat pipes, modular power electronics tightly integrated with the motor and integrated thermal management system.

Low-cost rare-earth free electric drivetrain for EVs/HEVs including the motor, low-cost inverter and thermal management system:
This part of the presentation will provide an overview of a DOE project led by Marquette University to develop low-cost rare-earth free electric drivetrains for hybrid and electric traction applications. The target is system cost < $7/kW, system power density > 12 kW/liter and DC bus voltage > 700V. The project introduces novelties in the electric motor, electric drive and thermal management system. The focus of the presentation will be on the motor side where novel design combining different types of magnets have been developed and evaluated.
