Compact Integrated Hub Traction Motor and Inverter
Agency / Branch:
DOD / USAF
For the past 20 years, UQM Technologies has developed wheel motors, integrated motor/controllers, direct drive, and geared drivetrains for advanced vehicles. For example, the company is currently producing direct drive wheel motors for wheelchairs (over 45,000 manufactured to date). This experience, combined with a new three-dimensional motor topology, technology advancements in magnetic materials, and improved power electronics will be used to meet the requirements of Air Force ground support equipment. In Phase I of this effort, UQM Technologies will design an in-hub brushless permanent magnet motor and integrated controller that will eliminate a conventional drivetrain and transmission. Trade studies will include diameter versus length, two-dimensional versus three-dimensional flux paths, and direct drive versus geared solutions. Requirements will include equivalent performance to ICE-driven vehicles, equivalent or improved safety features, and cost effectiveness. The Phase I will result in a clear feasibility assessment of electric hub drives.
