Continental's electric motor saves rare Earth metals

Continental Uses Performance Electric Motor Without Rare Earth Materials

Finding the careful balance between lowering pollution and making electric cars even more efficient is a tricky deal but companies, such as Continental find intelligent designs and systems that lower the burden on our planet Earth and still manage to raise performance.

Manufacturing or driving cars raises the issue of pollution. While there are no silver bullets, companies are finding better ways of refining components while reducing global footprints. Continental might be a company you associate with tires but its other departments are involved with ways of reducing pollution, refining electric car components and making electric motors particularly efficient without sacrificing pollution.

Continental’s Electric Drivetrain Department. Continental has been converting regular cars to full electric by using its in-house components, which include electric motors, batteries, electronics, propulsion, charging systems, as well as its Conti.eContact tires. For instance, its Conti.eContact tire offers an intelligent solution to low-roll resistance solution by moving away from a 195/55R20 tire and replacing it with a traditional 205/55R16 whose flexible sidewall help reduce energy loss when deflecting or rebounding and substantially reduced rolling resistance.

Electric Motor. When it comes to electric motors, we know we have a choice between AC and DC motors. DC motors are cheap and do fine with a homemade conversion but they don’t allow for regenerative braking, something AC motors can do. Continental’s electric motor goes a step further by using a synchronous electric motor that is “externally excited”.

re: Flexing Tire Sidewalls - I would have thought that the energy lost in rolling was *due* to flexing of the sidewall, which in turn heats up that tire (and that energy comes ultimately from the propulsion source).
My exact same thought. I'm actually talking to Michelin guys to have them explain how their low roll resistence tire works. It tiruns out, they find a way to inflate the tire more than the usual 32 psi which compensates for belt slack. It's absolutely different then what I had imaged. I was also impressed to see how many parts go into a tire. It's not just one big mold. Thanks, Nicolas
