This is a stand alone hydraulic unit with built in resivoir and pump.....max speed of unit is 3.1" a second and it has a hiqh force that will be adequate for what I am doing. This actuator will work but it is just a dc motor driving it! I need some sort of position control for my application.
You could attach a linear pot to the moving shaft, or simply use foward and reverse travel limit switches.
If I use a pot as a feedback device then use another pot as an input device to change the position? For every change of voltage the shaft will move a certain distance? Would that work?
