I'd love to just see a quick and dirty prototype. Perhaps if a facility can't be created or the means not available, we could possibly create a prototype with people here? There are a lot of us, and each of us brings something unique to the table.

@ WheelMotor, I encourage your efforts and look forward to hearing more.

People with the capability to build a prototype also know that unsprung weight is a major issue. Unless you have a breakthrough that fixes that problem, you won't make progress.

A little research will tell you that beyond just dealing with ride and suspension issues, shock is a major issue. Microcracks that have little effect on physical strength have a major negative effect on magnetic and electrical properties. The resulting field concentration results in localized heating, which encourages crack propagation.

You often hear "progress is made by people that haven't heard it can't be done". A more accurate phrase is "progress is made by people that understand why it can't be done the way that was tried before".

I registered to these forums so that I could "LOL" at the last over 3 years of posts in this thread.
Great read here...really looking forward to gaining the necessary knowledge for my first conversion.

Any updates on this? They seem to have it fitted to a variety of working prototypes. Is there a price for these things? I noticed a quote of 35k a piece, which is a bit out of budget, but still. A few years have passed.

Three and a half year have past ...

And..........?

I did not see any affordable retro fit WM kit appear so far. If I am wrong please post here the offers.
A lot has changed in my live in the past years. I will become father again in the next 14 days ...
I am seriously considering to give the WM project an other shot in the coming weeks. Will keep you updated.

Actually that was the point that some of us tried to make, that "In Wheel Motor...affordable", was not going to happen.

These days I am breaking my head about the max frequency of core material of the coils.
Very interesting reading here.

Yesterday I made a microscopic first step in my second attempt to develop a commercially available Wheelmotor. I bought 1 new bigger rim + tire for my 1996 Jaguar XJ6 X300. It is the Jag with the newer rear suspension, with the brake discs outside. This car has the standard suspension like on any other modern car.
3.5 years after I started this thread, I have more time and I want to try an other approach. I think that we can do here something that big constructors can't. It is not my intention to present here a complete solution with 3 years garanty . A Wheelmotor has inherent limitations. For example it might break down if you drive over a pothole. Probably a hub-motor is not even the best solution for an electric vehicle. But under sertain conditions it might be attractive for a DIYer to retrofit an existing car with 2 hub-motors, so that an ordinary gas guzzler can be converted to a hybrid or the hub-motor might be used as an electric turbo.
And because I haven't seen a lot of custom made affordable Wheelmotors anywhere else, I want to (slowly) give it a shot.
A retrofit like the one proposed HERE is not possible because it would imply that your wheel goes some 10 cm outside of the wheel arch.
I would like a few characteristics to be part of my Wheelmotor design.
1) It must be retrofitable to any existing car and invisible (from the outside)
2) It must be cheap to be replicated so that I can produce it "affordable" in a low labor country.
I might develop it here online. We could do it open source, with this difference, that I will actually make the prototype here with pictures. Input from somebody who has a simulation software is very welcome.
