Main Question or Discussion Point
I have a system where a cable is pulled down with a load of 100-200 lb. I need a motor that resists this load with a force that can be programmed to be anywhere from 5-30 pounds. I don't want the motor to stop the downward motion, just to offset the magnitude of the force pulling down on the cable. I will be using an Arduino to control the level of resistance provided by the motor. Is this possible and if so what type of motor/system could I use? Thanks!
