Well, im designing some additions to my existing system and i cant seem to figure out for the life of me what the name of the motors are called that are used to move objects like amp racks, doors, enclosures. they are a 12v motor with a screw attached (ram type). lemme know...

thanks in advance
Axis

P.S. check out my website its updated often. currently im putting a 350 in my 95 blazer

are you talking about a stepper motor with a worm gear?

Scouse Monkey · 02-14-2005, 09:32 PM

linear actuator? i think they use screw jacks.

Yes... Linear Actuator

this is a cool game - "name that part"

maybe i should have answered with a question like that stupid game show:

"what is a linear actuator?"

scott_fx · 02-14-2005, 09:40 PM

well, i was gonna say that

I am looking for this type of Actuator too, looked all over, the only ones I found were too expensive. If you guys know any source of reasonably priced ones pleas list them.

I might know a guy that was selling 2 linear actuators with a 6 inch throw, I think it was 75 pounds per actuator or something. He wanted 100 for both, but dont know if they are still for sale.

They are VERY expensive though, I asked the guy about his, and they cost him 200 a piece.

Expect to spend 100 or more for each one.

Edit: If you are just moving an amp rack, a stepper motor may work as previously posted. Then you could probably get the cost down to 50 or so

not sure how cheap you can find these but look into the worm gears and motors on power seats.

If you don't want to spend coin, make your own. If you have access to a machine shop it's easy, if not, it'll be kinda ugly but you can do it.

Another option to think about if you want linear motion is old line printers. If you grab the stepper motor, belt, carriage and rails you've got a prebuilt system. If you don't want to build a stepper motor controller (can be a *****, but is usually not too bad) you can just swap the stepper motor out with a servo motor and use limit switches to start and stop it.

PM me and let me know if you need any ideas, it'd help if we knew what you wanted to do with it
