IPM optimized (e.g. Votol, ASI, maybe Nucular, haven't found any concrete info) controller,

None of those controllers are IPM capable or have MTPA algorithm for IPM motors, it requires dynamic phase angle adjustment to the specific motor. APT96600 might work but the field weakening setting in my controller did not work so i can’t be sure.
A noload would not answer this question either, has to be multiple dyno runs to get optimised phase angle for each rpm.

Yep thats good for torque, but not so good for iron losses.twikis said:edit: The airgap seems to be quite narrow, that's nice
Thats around 900W which i find is a bit on the high side for ~4000RPM on a motor like this.larsb said:It’s at 12.5A / 72V on my motor, don’t know exact voltage when i tried it.

Full size KTM 250 exc, QS3000, Nucular 24f. 18s 3kw Chevy volt.
Vas needs to build a 36f with 750 phase amps.

I don’t remember where I found the image i worked from, but it had enough dimensions that I was able to calibrate and work from it. I was able to 3d print a prototype motor mount using what I have, so I know it’s at least accurate enough for that. As for the sprocket, the model doesn’t show the shaft accurately, but I’ll send pictures with dimensions in a bit.
With regards to where to buy it, I found aliexpress to have the same prices as the official QS website, and then you don’t have to go through the hassle of placing an order by email. If you put a comment on the order or message them with your order number right after placing it, they’ll send it with any size sprocket you request.
