How Do I Use A Servo Control Board To Operate A Linear Actuator?

Skip to comments   Jump to end

Hi All,

if you are using a 12vdc linear actuator without feedback and you use a servo control board (6v - 7.2v) with a pot connected to the actuator for feedback, where would the linear actuator's 12v leads connect to being the motor outputs of the servo control board are a lower voltage?

Would you also have to have an H-bridge connected to the servo control board?

Thanx.

IJust an FYI for those interested. I did find a 10k slide pot that is 128mm (5" ) long on eBay, which means you can go up to a 5" linear actuator. Although 5" linear actuators are not common, they do exist, plus you can always take a 6" actuator and internally adjust the limit switch to 5" if needed.
