If you read through the thread you'll see the update is that it's not happening, as some of us predicted.

The reason why it did not happened so far is :

1)The unsprung weight. Everybody who tries get stuck at this problem. The solution is to put a simple electric motor inside with 2 cardans to the wheels. Result: neglectable friction losses and a conventional, well understood manufacturing and fine tuning.
Making a lightweight electric motor of about 15KW that fits in a wheel is not yet possible and for sure beond the reach of this DIY forum.

2)Dirt and moist entering the EWheel motor. Easier to solve, but not to be underestimated in view of longevity.

However, in some limited applications Wheel Motors as an after market fit to an existing car might be an option, in countries that allow that. Nor central Europe, nor Egypt, countries where I am, have any chance for commercial application in after market sales for normal private cars.

Think also: Why are the guys that are developing the Chevy Volt not using Wheelmotors ? Why are nor the Mitsubishi I Miev or the Nissan Leaf equiped with Wheelmotors ?? For the same reasons !

I hope this answers the question "why it's not happening, as some of us predicted."

All you've done is laid out some of the problems with wheel motors that some of us were quite aware of from the beginning, and why we predicted this project would not come into existence as originally planned. I was not asking a question as to why this didn't happen, I was pointing out that it didn't happen, just as predicted. Wheel motors are not a practical solution for most EV's at this time.

May I remind you of this?

You thought you could do an affordable wheel motor, (title of the thread), for around $1500, and some of us disagreed. We happened to be correct.

Hey, JRP3 ... what are you ??? A preacher ?

The question was (with hind sight) not "could a wheel motor be made for 1500$", but "was there a commercial application for this motor?"

So far I had contact with 1 potential commercial vendor, but cooperation happened to be very very difficult. So it broke of.

As of now, still commercialization is possible. As I said before in this thread, I will not build a Wheelmotor, just to show that it's possible, because that would be like reinventing boiled water, isn't it ?

And I will not spend thousands of dollars like PML just to show a non commercial prototype and than go bust. Don't forget that a lot of people have shown the PML wheelmotor on a car (example Volvo and Ford and their own Mini) but so far I have seen all the majors opting for the classic inside electric motors.

So you are right JRP3: No prove of cheap Wheelmotors made by me, if I can't find somebody who might be interested to buy them.

Your next reply might be: Who will buy what does not exist yet?
My answer might be: This potential client has just to prove me how solid he is and convince me of his potential. Than he has to "gamble" 1500$ on a prototype. If he can't afford this to prove his commitment let him than ask prices to prototype such a motor in the USA or Europe and than we speak again. 1500$ is really peanuts in this context I think.

I would be interested in looking at a 10kw continuous motor for a 17" automotive rim.

Buying a house will be cheaper.

I love the idea ... but the issues involved can not yet be solved inexpensively.

But if you want to spend Tesla like amounts of money for less performance ... go ahead.

He won't be spending anything since these motors don't exist. Besides I think he's a spam bot.
