Paul & Sabrina's cheap DIY 144v motor controller

[MPaulHolmes]

I'm ordering them either today or tomorrow. I'm also ordering the AC control board, AC high side driver, AC low side, and AC power board, DC high side driver, dc control board, and new DC power board all at one time! Needless to say, I'm being obsessive compulsive about checking for mistakes, since it's like the cost of a crappy used car. haha

I will probably need a set of boards for the AC controller also. I have a SepEx motor that I need a controller for. Just let me know.

Hi Paul,

Are you ordering your new AC & DC board set to continue you’re de-bugging? Or are the PCBs ready to sell to the ReVolt group? Will you be selling them out of your DIY on-line store? What price will you be selling them for?

The nice thing about this last prototype I just finished is the control board is now good. There were 2 mistakes on it that I had carried over to the AC and new DC control board layouts, both of which are now fixed. The DC one was changed to a high side drive, which Lee Hart suggested might be a better idea. The just finished prototype is low side. I think it will work well, but I think the high side will work better. The AC board is new but mostly tested, since it's so similar to the DC control board. I need an AC beta tester. AC cars are much more unusual though. I have a 100 pound AC motor in the garage, and about 350v in batteries for trying it out, but that won't be very good for the car. Also, Isaac is letting me borrow a high current pmac motor for testing too. I think the stuff is basically ready to put on the wiki. It's unlikely to have more silly mistakes.

Hmmmmm - I could talk to Tom, see if we could trick him into letting us put it in his AC Dodge Neon.

His Neon is running a stock AC drive right now at something like 300v. Would that work OK with the new Open ReVolt AC?

Hey everybody, I have this crazy idea that maybe we can turn this generator into an AC motor:

Can someone give me some insight on what to expect if that were possible?

I am working on a budget so I'm trying to beat the system until they realize and jack up the prices he he!

And Paul if you don't mind I would like to help in this AC project. I would like to order a couple of AC boards and the list of items required to put together a couple of AC controllers.

One is going to go into my old Ford Aerostar and the other on my CBR1100XX which I am turning it into electric after seeing MotoCzysz win in Australia.
Peace.

It should be fine. I'm going to use 600v igbts.

I just ordered 7 new board types! $1830.77. That really hurt, charlie...
4 layer ac control board
high side ac driver
low side ac driver
ac power
dc power
dc high side driver
dc control


and now a word from Josiah:

[Alcibiades Ramos]

Wow! that is around $261.50 per board!

[MPaulHolmes]

well theres a big setup fee for each type. But i got 10 each of 5 of them, and 5 each of the 2 power boards.

[Alcibiades Ramos]

Well I would like to know if I can attemp this but before I need to at least know what I'm doing he he. So I have two questions: for the big system can I use a generator like this:

Generator Head - 10,000 Watts Max, Belt Driven

And the second question is can you provide me with the circuit and the board layout for a 48v 40a 3 phase controller? I would like to experiment (burn) something cheap before getting into the big fireworks he he!
