Electric Car in-wheel motor Siemens eCorner
Posted by admin | Under Autos Thursday May 20, 2010SUBSCRIBE to stay current on EV news ^ ^ ^ ^ ^ electric-vehicles-cars-bikes.blogspot.com Ferdinand Porsche put wheel motors on a battery electric car in 1897. They built about 300 of them and there were 4WD & FWD versions. He also made a hybrid version. Amazing that 112 years later Wheel motors still aren’t in mass production. Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and driveline inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous. With an Electric Car it costs just $1.00 per 100kms with MUCH more performance than with petrol at $20.00 per 100kms. Electric Car in-wheel motor Siemens eCorner
@retaessa69 What an idiot!
OK,OK,OK What would happen if you hit a pot hole but a major pot hole ?wont the added weight of that motor on the wheel be sooooo heavy that it will bend the wheel and stop the wheel from spinning make you crash and short out that wheel make it burn up and ruin the motor ……not so smart!!! thats why it isnt sold. looks nice on video tho.
@apedomann21 Batteries are still too expensive…
tsport100 knows his stuff! The redundancy offered by carefully designed electrical (braking) systems is actually superior to hydraulic braking systems which can suffer from leaks, wear, air in the lines, dampness in the friction assemblies, etc; many things that an electrical system is immune to…
This is the same drive than my electric bicycle, I am very interested in it for my nexw car (I wish it will be an electric car).
In France they are schepticals about the In-Wheel they say this” a washing machine’s motor in a wheel, is it serious”?
I imagine an Audi Qauttro with four wheels like these ones.
Hey I hear the Terminator melody in the music.
this is from 2007! Why havent they starting to make it yet??!
I want that on my car :3!

@tsport100 y piensa en el peso perdido por usar materiales de carroceria de las generacines pasadas
@meanman1992 te has puesto a pensar por que los carros no son más livianos, o mas eficientes, y sabemos que se puede? piensalo, no eres el dueño del negocio pero piensa por un momento como si lo fueras
@stealthcentral brushless motors can have their respective parts encased in plastic. there are no contacting parts, which is just one of many reasons that makes these motors far superior to internal combustion motors. there are also designs that incorporate batteries into the hub, for a complete system. now imagine purchasing 2 hub motor wheels and upgrading your geo metro with burnt out combustion motor… or dare i say it… boat car?
who here laghed at the name?
@AlaricAchos You can’t have ‘power loss’ if the motors generate power during braking!
As there are 4 separate motors each with their own inverter the system already has quadrupole redundancy, that’s more than any aircraft, the space shuttle or any hydraulic car braking system.
The only ‘back-up’ required is a bank of resisters to burn off braking energy when the battery is full or gets disconnected. A ‘rheostat’ braking system is used on 400T mine trucks and 20,000T freight trains.
@tsport100 no you still need the saftey back up of friction braks or a fail safe if case of power loss
With these way of directly having the power on wheels. A lot of saving on weight can be made. Transmission, propeller shaft, drive shaft, axles, differentials/housings are gone. 4wheels, 6wheels, or 8wheels, can really be made ‘All Wheel Drive”. With todays techno on automotive this is really good. But when can this be mass produce on every car makers in America? For sure outside America they’re doing this.
How is it in cold and snow? I am from Iceland, and when it is -10 ot - 25 °c battery in car go bad faster if you don’t use the car some days ” when car is moving then it is charge battery” ?
thanks a lot for sharing
all your eggs in one basket, idl this.
EV’s and plug-ins are finally coming to the states in 2010…Volt, Coda, and Leaf first….can’t wait to plug it into my homes solar system…
trrue, i agree, electric cars are already operational!!!! There is a company called Better Place and there cars are now fully working in Israel, Denmark and Australia and will so move world wide. It has a lot of cool features. Check there youtube channel out.
When???
I hope that goes to the market soon. Most people cannot afford gas. Getting costly.
yeah, this means “we have more work so you’ll give us more money”… then comes a stupid rock, fits correctly in the middle of this thing and boom! engine blown up!
German Hightech but greece say to us Nazi!!..(that was a another gerneration!!)..what has greece??…nothing!!!..you loser!!
This is such a fantastic video. I would love to own a car with electric motors placed in the wheels. 4 with good lift would be especially great!
