Hi i’m a little lost , i’m trying to power a hydraulic spool block / valve lever control using a linear motor ,
its my first time using this type of control and i have made a couple of blunders to date ,
i’m using a rs potentiometer joystick with a acutonix linear control board and a L16-100-12-p linear actuator ,
however this actuator is far too slow responding ,
the maximum stroke that i require is 15mm in each direction but must be capable of moving 100nm load ,
i have tried the L16-50-35-12-p but although the speed is better the unit falls short on its grunt ,
the control aspect is critical as it has to be quick acting but to be able to mimic the control applied via the joystick ,
now i dreading the answer , i know i should’ve asked first . well i have this much for you all to go on , my lesson learned
any suggestions as to the type of setup would be greatly appreciated
regards glenn

Hi glenn123+,
There are many ways to make this system.
Have you considered a large Servo motor to provide the control ?
For example the Torxis i00600 servo could be used:
Torxis i00600 12V High Torque Servo Motor
The same manufacturer do have a joystick to R/C box which we are entering, attached is the image.
Manufacturer Description
These servo controllers use joysticks to generate signals to control any hobby servo that responds to the RC PWM signal.
This product is commonly used to control servos in a non-wireless condition where this product replaces a standard RC radio.
This simplifies operation where wireless functionality is not needed. These products feature a machined plastic housing and precision joystick potentiometers to create a precise servo controller.
Great for camera mounts, pan tilts, robotics control and testing, creative Halloween decorations etc. Does not include power adapter. Buy separately below. Note that all channels are fully proportional. Features spring return to center.
thank you for your kind thoughts ,
i have had some success using the actuonix L16-100-150-121p ,
however this unit is on its limit and to slow to respond ,
(i could use a shorter unit but not longer than the L16) i have a 12v dc supply .
in an ideal world it would be good if i could replace the L16 with a quicker linear actuator that would hook up with the acutonix linear control board as this side of things are already in place.
i would need potentiometer feedback for the progressive like for like control
Any suggestions ?
Kindest regards Glenn
Hi glenn123+
There are not magical answer to this, if you need more speed you will loose torque.
Maybe the “L16-100-63-12-P” which have a 63:1 ratio.

thanks for the help and advice Eric , im with you on that one , I was trying to suggest that you may be able to give me some advice on an alterative make of actuator that may be able to deliver the requirements and still use the actuonix board for control .
regards glenn
Those actuators use very small motors, the torque is not high either.
Using a servo like the one we suggested would give you a LOT of torque and control directly by RC commands.
