Hello,
Does anyone have the schematics or at least pinout of the connectors? This one has a good "contactless" voltage control on the pedal (based on analog Hall effect sensor), but are there any...

In my humble opinion, the way how speed is connected is very dangerous, because these terminals are running at mains power potential and not referenced to ground. Shorting it to ground will destroy...

See this: https://sites.google.com/view/dmelec-celsiuss/bldc-drivers-and-automation. The controller in PM25 is wired in a "standard" way. The tachometer only gets +5V from the controller board.

About the picture size: original pictures are in ~2x2K resolution. They are ~2MB in size. This site scales then down and changes resolution to ~300x200 when uploading, the "uploaded size" is reported...

I found the seller on Aliexpress: https://www.aliexpress.com/item/2255799890270658.html

Picture of pinout one more time.

I lost original files with pictures. However, I bought "Weiss WBL290BV" Lathe recently, it was painted into a surprisingly similar blue as PM25. And, surprise, it had the same motor controller. This...

Additional pictures of the BLDC controller... I could not find schematics or any other information so far. Apparently it is microcontroller driven and there is a programming (?) connector in the...

Here is my first information on PM25-MV spindle drive control:

The machine comes with 750W brushless hall-based spindle motor which is controlled by the electronic controller. I am posting the...
