Motor controller to keep 3 linear actuators in sync

[font=Arial][size=2]I am seeking a recommendation for a method to keep 3 linear actuators in synk. [highlight=#ffffff] They are 12v, 12amp max, each and they have a potentiometer for feedback. They will travel only to their extremes of travel, and have internal limit switches. But, I need to keep the actuators in sync with each other, otherwise I would simply use a simple power switch to control them.[/highlight]

I have seen many programmable motor controllers that handle 2 DC motors and have the analog input for the control. But, I have not seen any affordable controllers like this that can handle 3 motors. Moog seems to have them, but they are over $3,500 !

Perhaps I just buy 3 single motor interfaces, that I connect to an Arduino. But, I am not sure if the Arduino has enough processing ability to continuously read 3 analog inputs, and control the motors. Perhaps someone else can tell me if that is viable…

Thanks for any recommendations.

Hi,

You can certainly use an Arduino with an appropriate DC Motor Controller to control your 3 Actuators.
The motor controller should provide enough current for the 3 actuators (at least 12Amps for each).
Or you can use 3 Motor Controllers (one for each actuator) interfaced with one Arduino board.
The Arduino will read 3 analog inputs from the actuators potentiometers and control the motor drivers.
Please take a look at our 10-30Amps Motor Controllers section.
You could use for example 3 x Pololu 24v12, 5.5-40V, 12A Motor Controller with an Arduino board.

Regards,
