I have an automotive suspension setup with steppers to adjust the dampers via a remote (in-cab) control. In looking at the steppers, they are 3-wire. I am not able to find any information (so far) on 3-wire steppers- specifically, how they are wired internally, and how they are driven/phased.
Does anyone happen to know anything about 3-wire? Any feedback, or links to info would be greatly apprecaited-
