Beth, acutally this is the way electric cars should be designed. Having one big electric motor is really a legacy of the ICE design philosophy. Of course, it made sense there. I always assumed that this is how electric cars would be designed, and I believe that over the years there have been such prototypes or design studies. Locomotives, for example, the real model for how we should be designing electric and hybrid vehicles, use a motor for each driven axle. Of course, becuase they run on rails they don't need one for each wheel. In the conventional vehicle world, companies like Audi have long touted all wheel drive, where power is feed to each wheel in an optimum way. With modern control systems and, of course, innovations in the motors themselves, this should be a no brainer for the modern electric or hybrid vehicle.
This seems like a great example of engineers thinking out of the box. Maybe I dont' know enough about the space, but putting motors in wheels as a means of increasing mobility on a single charge seems pretty unique--and compelling. Is any one aware of others using this as a mainstream approach?
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
