I'm resurrecting an old thread, because this story in the news caught my attention.

Protean unveils production in-wheel electric drive system

Wiki here: Protean Electric - Wikipedia, the free encyclopedia

Company here: Protean Electric | Protean Electric

Similar tech discussed on Ecomodder here: http://ecomodder.com/forum/showthrea...tml#post318890

In fact it's mentioned directly at http://ecomodder.com/forum/showthrea...tml#post348568. I'll post there as well.

The Protean Direct Drive has some interesting tech, a low-speed/high-torque design with integral multiple micro-inverters. This would enable the design I modeled in the mid-1990s.

I know, I know, ...open wheels..., blah, blah, blah. At this point I think it would have a Baja'd nose, and a Speedway dropped-tube axle with a U-shaped diverter/fender like the Mercedes Benz Silver Arrow.

Back to the motor[s]:

4.5" thick, 16" in diameter and ~100 horsepower
A commercial product on the market in 2014
Requires an 18" wheel and is geared for 1000-1500rpm
reference controler code for evaluation testing
communicates via CAN bus

Torque is dropping fast at 2000rpm; or, say 150mph without taller tires. Their videos suggest the motor has an open center so a driveshaft can pass through. Can a differential for inboard mounting be far behind?
