Citat: "...a Dutch company plans to unveil a bus in which motor and=20 wheel are one, a refinement that promises more miles per charge and a=20 vehicle that is safer and easier to maintain.
The company, e-Traction [

], has modified a=20 city bus as a diesel-electric hybrid. It has a small combustion engine=20 that charges the batteries, but propulsion comes from two electric=20 motors with tires attached that serve as the rear wheels...In addition,=20 some electronic tricks can make the motor turn at speeds fast enough to=20 run the bus without gears, he said. The result is to drop the=20 gearbox...Meanwhile e-Traction is also working on a Mercedes Jeep=20 borrowed from the Royal Netherlands Army and a Range Rover. Both will=20 have four motors, one on each wheel..."

Citat: "... A self-propelled electrically powered wheel, operating at more than 90%=20 energy efficiency, with optional 180=B0 electric or mechanical steering=20 including suspension, ride-height control and shock dampening, delivers=20 up to 120 KW of direct drive traction at the only place where it=20 matters,.....at the wheel =2E.. The tire is mounted directly to exterior of the direct drive motor =2E.. Braking is done electrically, or more precisely magnetically, by simply=20 powering the engine(s) in the opposite direction. The energy of the=20 forward motion arrested by the braking action is converted back to=20 electrical power. This process is called regenerative braking. When=20 simply coasting down a hill the engines also function as generators.=20 The regeneration of power adds substantially to the endurance of the=20 batteries, which lessens the need for auxiliary power supplementation =2E.. The onboard generator, including a fuel cell, could use a wide variety=20 of fuels =2E.. After five years of development the introduction of TheWheel=99 took plac= e=20 in 2001 with its placement for the energy company NUON as a generator=20 driven by a watermill in =93het Geldersch Landschap=94. This unit runs t= he=20 equivalent of 100,000 kilometers per year in a wet environment=20 generating roughly 20,000 KWH annually..."
