Hi!
I'm in the early stages of noodling a project to build a wood working clamp that's electrically driven. For this, I'd like to be able to set the clamping force I'd like to exert, and then have the motor drive the clamp until that force is achieved, at which point the clamp is locked until things are dry.
The motor would presumably be a brake motor so after the clamp is set the motor brake engages and power to the drive circuit would be removed. The motor brake would hold the clamp shut.
What I'm not sure how to do is to drive the motor until a given clamping force is achieved. Presumably this is a function of voltage or amperage consumed by the motor, and the specific numbers can be empirically measured with a scale when commissioning the machine. But the specifics of what I'd control and how are a bit beyond me. Anyone have suggestions?
Thanks,
-Ben
