GM Hybrid motor

[accordlx]

Has anyone ever seen anything like this winding configuration?
We have no name plate information but the client says it is a GM Hybrid motor/3 phase. He doesn't know the rpm rating.
My dilemna is where to get/ make coils to rewind this stator.

Dunno about others but I'm not going to unzip a random file found on the internet. Unzip the target file and re-post a link to the unzipped file.

Let me try it this way.

That's more like it!

Is this part of the motor/generator of a Chevrolet Volt or some such similar apparatus?

If that's the case then it is a proprietary design (with a GM part number), not something you can get off the shelf, and it probably was put together in a manner that is not easily duplicated by someone accustomed to rewinding NEMA frame AC motors.

What is the issue that prompts you to want to rewind it? Why are you trying to do this?

If it's to fix your car then the best bet is almost certainly to find a junkyard complete working transmission and just swap the entire assembly with your bad one.

Otherwise, if for some reason that's not a viable option, go to a shop that specialises in rewinding motors and see what they say. It is highly likely that you will be told that they can't do it. But, I'm no expert in that field. Maybe they can.

If you're that shop and someone has brought this part in for a rewind, then I don't know what to say, other than "good luck".

High performance motors (very high power density) are a whole different ball game from the one that operates your washing machine at home. The physics is all the same but the designs have been much further optimised, and that makes fixing them a much more detailed affair. If you get ANYthing wrong, even in the smallest detail, so that it does not operate as per original specs, expect trouble.

It is out of a pick-up truck circa 2008 so I,m told. We are a shop that specializes in AC & DC traction motor rewinding & rebuilding. We took it in at the customer request to try to see if it could be reverse engineered. Wasn't expecting to see this.

Ahh, so it's the old 2-Mode Hybrid transmission, which ended up being a flop in the marketplace; there are not too many of them are out there. Good luck ... Any idea what's wrong with it?
