Waw, nice sudden controversy. Love that !
Seff, thanks for your support, I am a positive person too.
Although I usually don't like JRP3's pessimistic comments, this time he is of course right. I forgot the torque multiplication because of the gearing.
I did nothing else than optimizing, since my last post. And there is progress !!
Nope we will not yet beat the Lambo, but we have now a nice 117 Hp 87 Kw and strong 839 Nm from 0 to 120 km/h. With 2 such WM's we will have a nice 1678 NM. And that is already half the pulling power of the Lambo at 3000 RPM. Because the Lambo motor gives less torque at lower RPM. And the Lambo has to change gears, hahaha.
A bit more serious now. If we can make an affordable wheel motor that you can simply bolt on your car and add 200 Hp to an existing IC engine car, my project is a great success. There are a lot of real world parameters that have to be kept in mind, just two:
I don't want to change anything on the car. (very big limitation)
Torque numbers are limited by realistic battery power, dimensions, weight and cost.
My aim is not to produce the biggest motor, but the most efficient and as a second parameter torque. The missing gearbox is a handicap in "good for promotion" performance, but it eliminates about 25% loss too. And this during acceleration, but also during Regenerative Braking
I read a very interesting relevant article about Torque in cars on ElectricVehicleNews.Com
In the article they speak about this article about the Audi e-tron.
Karlo, thanks for your encouraging words. The controller is not what I am focusing on, but it will need our attention later on indeed. I have not seen yet a controler that has the required Volt/Amp specs that we need. (And that I can afford)
