I have obtained some servo motors, one bigger than the other.
They are brushed DC servos and i have the ancient controllers but i imagine they're not going to be much use.
I'd like to adapt the smaller of the two to fit under the table of my archdale mill, to give me a powered rise and fall of the knee.
It's a heavy knee and takes some serious cranking.
Question is, how do you drive a servo motor?
If i was to purchase a modern controller, is it possible to build a very simple interface to just do up and down? On a push button would work. I mean a power feed that you could set via a potentiometer like an align power feed would also work nicely.
A VFD driven three phase motor with gearbox would work but it would take up more space and i'm unsure if it would be as powerful as a dc motor.
