In-Wheel Electric Motor From Protean To Be Used In FAW-EV Bora EV

December 18th, 2013 by  

We’ve published stories about Protean’s in-wheel electric motor in the past. They generated quite a bit of enthusiasm as well as interesting commentary. Protean has now announced that it has landed a deal with FAW-Volkswagen to bring its in-wheel electric motors “to market” through the FAW-VW Bora EV, a 100% electric vehicle being manufactured in China. Assuming things go well, the dream of in-wheel electric motors in mass-market US cars may become a reality. We’ll keep you posted! For now, check out the news, plus a bit of background:

Protean & FAW-VW To Bring In-Wheel Electric Motor Tech To A 100% Electric Car (via EV Obsession)

I covered in-wheel electric motor startup Protean back in October 2012. Naturally, it takes a while for a company to get rolling, but Protean recently announced some pretty big news. It has partnered with FAW-VOLKSWAGEN AUTOMOTIVE CO., LTD. “to develop…

  • pankajkumar

    its great idea about the racing car and you know more about Brush Holder

  • drkennethnoisewater

    Have a wider optional version that takes wider rubber (for rear wheels) and has additional stator windings.. FOR MOAR POWARS!!

  • obserrvverr

    but why? water damage just begging to happen.

    • driveby

      no gimbals, no axles, all wheel traction if wanted… there are some pros to this approach. Biggest down side atm is the big mass of the wheel compared to a normal one, which is problematic from a comfort point of view (and probably driving dynamics as well).

      In regards to water and 230VAC.. do you have a desk fountain? Check out it’s motor, same can be done here. No worries.

      • Bob_Wallace

        In Michelin’s version of the in-hub motor they used electric motor/generators in place of the shocks and turned movement into electricity while allowing fine control over the transfer of energy back to the vehicle.

        With fast enough response times the vehicle should ride absolutely flat and not bounce along with the wheel.

  • Roddy Erickson

    This motor seems to fully occupy the volume that would conventionally have the brakes; is there backup braking capability if the regenerative systems fail?

    • Bob_Wallace

      In this illustration there is a mechanical braking system.

    • drkennethnoisewater

      Inboard discs, and presumably they’d be more reliable/less prone to overheating than the ones used historically due to regeneration reducing their utilization.
