Motor-in-Wheel Electric Cars

There is a Motor wheel developed by a Hydro Quebec spin off.

It has been around for some time and does perform well. They had a well performing prototype in the news.

Personally I think the state the roads are in Quebec most of the time forbids its usage.

As a performance standpoint, the inclusion of a motor in a wheel increases the unsprung mass, and adhesively affects the road handling and the shock level to the tires.

I have heard about the cost of replacement for hybrid vehicle batteries after 10 years, if you add tire and wheel cost if you hit a pothole or the curb, I don't see it.

Hi,

Heinzmann in Germany is an established manufacturer for these motors.

I used one for a totally different application.

could you be more specific please?

Hi,

did you look at the Heinzmann website?

if you did not find a solution, what are your needs?

I am using these motors for slow to fast drives with easy control possibilities and very low disturbances. These disturbances are forces in any direction and torques perpendicular to the drive axis causing vibrations if fast and causing distortions if slow.

These motors are used without the normally existing ballbearings for the purpose of ultraprecison machining: rigidly coupled to an airbearing together with very good radial and tilt accuracy to prevent most excitations.

With this combination of a good motor and a very good bearing (both ultrasmooth) we can achieve metalcutting of nonferrous materials with diamond tools and we get a roughness of down to 10 nanometer and a shape accuracy depending only on spindle runout and thermal distortions in the region of 0.1 to 1 µm.

Thanks for that.

Most of todays electric mobile vehicles have motors that are quiet efficient with control electronics and are well performing covering almost all RPM range needed , today major limitation as we all know is electric storage , why don`t I and you give attaintion in that area there is possiblity lots of inventories un tapped in batteries and energy storage devices , this is bigger issue than the hub motor , further you can search through google for details you wanna look .. thank you

Hello Gentlemen, Last month I spent some time with EVT [Electric Vehicles Thailand]. Here in Bali we have the UNCCC coming up and the green fraternity here would like to demonstrate that we do more than fillabuster about things, we actually impliment solutions. So I was looking for delegate transport vehicles. Anyway there's an in wheel brushless 48VDC motor in a motorbike capable of 50km/h and range about 80 km. Navigate to the Zeta page. Price? A bit less than USD1,000 http://www.evthai.com/ As the looming oil price crisis looms we engineers should be thinking just how to power the world. I took an electrick "Tuk Tuk" for a test drive and nearly flipped it over in reverse. "Hey!" I said to the engineers rolling in laughter "reverse and forward have the same drive speed" "Mai pen rai" [don't worry, be happy] was the response. Gotta love the Thai's, anything for a laugh and a bloody good range of electric vehicles.

PMLFlightlink and TM4 are good sources, as is Heinzmann for tiny versions. The obstacles to overcome are price and weight. Wheel motors are tempting for the obvious reasons sited by their promoters. For a heavy vehicle, weight is less of an issue, and if you are thinking in terms of SUV ride and handling dynamics, rather than Porsche qualities, then weight is less of an issue. Like so much in the electric vehicle world, there is the chicken and egg problem re pricing: Once the volume is up, prices will come down -- but how to get volume up with such high prices?

In motor scooter sizes, the cost is more reasonable. Unfortunately, these motors have speed limits, so even if you used four motor scooter drives on a small vehicle, you'd find the speed too low for highway capability.

But check out the four wheel drive Mini on the PML site. 640 HP is impressive. I suspect that many people will not accept the wheel motors alone as the braking source, however. I'd like to have hydraulic backup.

This seems old news to me as this WIRED blog shows.

This could already be done with todays technology and should not need re-inventing the wheel, or any other technology, at all.

Don't tell me you are on their team?

??? Was this post suppose to be in the folding car thread?

Did not know about a folding car thread. This is just here as it states these little cars plan to use in wheel motors.

Seemed obvious to me to combine them, thats all.

Definitely. Ferdinand must be rolling over in his grave: 100 years later, and wheel motors have still not caught on.

"What do we know?" Well, this is an old OLD idea, first of all - see http://www.hybrid-vehicle.org/hybrid-vehicle-porsche.html for what was already in production prior to the turn of the LAST century! Yes, 1899. And to whoever said something about it not being Porsche-like, well . . . that's not quite accurate. The obvious disadvantage is horrific unsprung weight penalties unless you're moving slowly on level and smooth surfaces.

Not disputing the content at all, I do wonder why they call it a hybrid as it is clearly just electrical?????

It is not possible I think that this IS THE Porsche person later to work for volkswagen which then diverged and became Porsche, Is it? He must have been very old indeed by that time.

Still good post.

The hybrid Porsche is often cited as being the first hybrid car. It is as hybrid as anything today, using a petrol engine to drive a generator, which fed the electric motors at the wheels. The Chevy Volt is also a series hybrid, and if you are designing a car to be a plug-in hybrid, series operation makes at least as much (and for simple vehicles like my own X Prize entry -- more) sense as a parallel hybrid.

Ferry (also a Ferdinand) Porsche was the son of Dr. Ferdinand. But the elder Porsche was still around and signed off on Ferry's 356 design -- the first of what we think of when we think of Porsches.

Actually the Porsche firm existed before the first VW, which was one of their design projects. Here's a history.

Ok so it has got a petrol engine as well then. Must have tried to read it after too many beers.

Thanks

The Owens Magnetic was another early (Jay Leno has one from 1916) serial hybrid, but it avoided the unsprung weight issue. Or, you could see it as sort of the precursor of the CVT (Continuously Variable Transmission). It seems like an idea worth studying with an eye toward bringing it up to current technology.

HI, These are my ideas, any questions?

HI,
