I bought the better setup. But I think I need a different potentiometer. The one that came is a 470k.

I have a video showing exactly how to deal with that issue. ua-cam.com/video/04d0u1RJyXw/v-deo.htmlsi=ny3cYxA6KkqHJn8Q

None of those will work on my 3 phase treadmill motors! Im gonna cry now,,,,

You need a VFD which is far superior albeit more expensive.

1:25 So, you don’t recommend using the cheap controller to for a treadmill motor? 😈
(Don’t answer, im just trolling).
Those small rectifiers do need heatsinks. I’m not saying that that would be sufficient but without one they’ll fail well below their maximum ratings anyway.

I used a heat sink and they still failed.
