Seeking LInear Acutator control

by EvanBren on Wed Sep 13, 2017 1:41 pm

Hi,

I want to get a dial or keypad to create discrete stopping points for this linear actuator by Servocity (Link: https://www.servocity.com/sda24-263)

For reference, Servocity's standard controller is here: (Link: https://www.servocity.com/digital-manua ... controller)

Sorry if I'm at the totally wrong place! Someone recommended ADAFRUIT and I really don't know what exactly you guys do and I'm not an engineer. Any help or guidance would be really appreciated!

Thanks,
Evan

Looks like you could do this with a MOSFET to control the power and an analog input for the pot.

Thanks for the reply. Do you know anyone or a firm I could hire to assemble or configure such a device?

Hey Evan, check out this youtube video:

Here's a link to the adafruit part number for the MOSFET

Does this help?

Can you describe in more detail what you want to do? I'm assuming that the ServoCity controller is not adequate for your needs.

To create multiple stopping points, you probably want a microcontroller with analog inputs to read the position feedback from the actuator. An Arduino or similar microcontroller could handle that. You will also need a pretty robust motor controller. The motor for your actuator is rated at 3A "no load". I would expect that you would want something rated for at least 10A if you are moving any significant load.
