Ha by the conversation there it looks like it is a joke but cos it is a professor you think there is something there, but who knows maybe he is smarter then all here and is up to something that can save some petrol money... yes it has been 4 years i was just looking about in wheel motors and came up to this place and i didnt even knew i was registered with this flippin forum haha

It is not easy to get some small quantity of Electro steel to laminate your own BLDC stator. For this reason certain types of BLDC motor driven washing machines are even scavenged to rewind the stator.

The company ThyssenKrupp is prepared to help us out and I will update with the progression.

Hi guys,

The latest evolution of our BLDC inrunner modeling has resulted in:

A motor of only 210 mm outside diameter x 250 mm long.
140 Volt 600 Amps max.
400 NM from 0 to 500 RPM and than sloping down to 130 NM at 4000 RPM !
Water cooled and specially winded.

We are now in the price negotiations for the electro steel lamination purchase and cutting.

Once we can make the motor we can measure how long this liquid cooled bomb can deliver its 60KW before overheating. We developed some very "cool" liquid cooling system for the motor, so we hope that it can have a very high power out for at least 8 seconds. By than the batteries (that we can afford) run hot too.

My latest way of thinking to make my Jaguar Hybrid, is to replace the Air conditioning pump by this BLDC-M. I live in a cold country. So it will be geared and from standstill the jag will have 400NM + about 100 NM from the IC motor. You remember our torque discussion: 500 NM geared ! I want than to regulate the throttle so that the electric motor does the hard work under acceleration and than the IC takes over ... Pitty that REG braking will be hindered by the Jags torque converter in the autobox.

Yes, you've just discovered the HPEVS motors, that many of us have been using for years

Four years ago Major said, good luck with the technical issues. Quid errat demonstratum. (sp?)

Nevertheless I admire you perserverance.

Thanks for your thoughts.
At the end of the day, this is a DIY forum and most of us are amateurs. I am doing it as a hobby and I learn along the way. I write here just a diary of my quest to try to make a really affordable BLDC motor. Of course, the industry is for serious business and big money. But I have time.
Our latest setback came yesterday, when an acquaintance that should do the water-jet cutting of the lamination wanted a healthy 1750 euro for it.
But I am contacting every day a company here and there and sooner or later we find solutions within the budget. Because that is all what this thread is about: Try to make a big DIY BLDC motor for a really affordable price. In or outside the wheel.
My friend Seff and I spend every day several hours on this BLDC motor.

And today we got also good news !
The company "Laser Laminations Inc" from the place Warrior in Alabama USA gave us an "affordable" quote for the lamination of our stator. Work of cutting and steel included 560 Euro !

Rest the problem of shipping this (probable weight 10 Kg) stator from the US to Belgium.
If anybody has an idea about this, pls help !

Does anyone have experience ordering motor parts from http://www.phasemotorparts.com? That understands what to order to get the parts made for a specific set of desired performance specs.
