wow, sorry to hear that!
things got hot somewhere melting the insulation on the rotor windings and creating the HV fault/short?

Already spoke to my service advisor/bestie at my local audi dealership and they're thrilled about the opportunity to push my broken POS around the property to fix the air suspension.

I am curious if Taycan has similar coolant leak problems on their motors?

The Q6 Etron is the closest, but pumps oil through the rotor in a vaguely similar way to my plan to cool the rotor with transmission fluid.

Thanks! How do other cars cool the rotor? How does the Etron GT do this?

It's worth noting the ID4 uses an eerily similar motor layout (but permanent magnet instead of induction, slightly more efficient) which disproves my thought they they did coolant rotor cooling because they hollowed out the rotor.

but passive cooling, which is why I thought I might be able to get away with that on our motor. And it seemed to be working fine until my motor shorted out.

Just realized @HCx you are also in AZ. The summer time would be a test for your solution for sure. After it is proven work, do you have plan to commercialize it? I like the car but this motor issue makes me hesitate to keep the car long term.
I can't imagine I'll have a fleet of Etrons in my wake waiting to do this.
Then again since you can get one of these for 2 nickels and a complement now....
