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?
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
