Axial Flux Variable Gap Motor: Application in Vehicle Systems

  title={Axial Flux Variable Gap Motor: Application in Vehicle Systems},
  author={Sung-Chul Oh and Justin Kern and Theodore Bohn and Aymeric Rousseau and Maxime Pasquier},
Alternative electric motor geometry with potentially increased efficiency is being considered for hybrid electric vehicle applications. An axial flux motor with a dynamically adjustable air gap (i.e., mechanical field weakening) has been tested, analyzed, and modeled for use in a vehicle simulation tool at Argonne National Laboratory. The advantage of adjusting the flux is that the motor torque-speed characteristics can better match the vehicle load. The challenge in implementing an electric… 
Test and simulation of axial flux-motor characteristics for hybrid electric vehicles
For each operating point, the optimal air gap is estimated based on the measured efficiency at different air gaps, and the motor model is developed using the estimated optimalAir gap and efficiency and analyzed with a vehicle simulator.
