How to Interface a 4-Wire Vacuum Suction Motor from a Vacuum Robot with a Raspberry Pi?
Hi, given the four wires, perhaps it is controlled like a BLDC (brushless DC motor). I haven't worked with them much if any, but I believe they typically have three coils that need to be energized, and maybe the fourth wire is a ground? That might be a good place to start, and controllers for such devices are readily available.
A stepper comes to mind too, but those are generally lower speed so a vacuum would make less sense, but the way they work is similar.
So maybe search for soemthing like "BLDC control with Raspberry Pi?"
