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…
