Innovative Motor and Generator Technologies

The proposed program meets the objective of improved torque density, power density, and efficiency through a topology that combines permanent magnet and reluctance components. The proposed technology improves upon commercial versions of this topology (most notably, the Toyota Hybrid Synergy motor) through a rotor structure that delivers higher torque and speed. The Phase I program includes the design of a machine in the 50 to 100 kW range (scalable based upon stack length), demonstration of the high speed rotor, and planning for future prototype and production phases.
