Newb question about operating actuators

Hello all, about one year ago, i decided to start building a racing cockpit, now it's done, and working.

You know how it is, now I got my eyes on motion sim.

I recently found this actuator(see picture), I have no idea of which distance/sec it's capable of.

I don't even know if it works and I'm not sure how to test it, what kinda amp rating should i look for on a power supply?

I think i have a 32v/1.0A power supply from an old printer. would this be enough?

Or else, I thought of using an ATX psu and connect -12 and +12 in order to get 24v...

Also, i have a doubt about ground, if blue is +36v, then green is ground, right?

but regarding the pulse signal, I'm not sure how it works. Is it the same with every DC actuator?


Thx for any help

Where did you find this??

This is industrial servo actuator with normal RC PWM signals!!! You just feed it with the position signal and it goes to that position asap!! Nice!

You can drive it using my AVR motion controller 1.5 (with RC servo motor firmware) and feed it with power from any source that is capable of providing 36volts and about 1ampere.

Do you have any other photo that we can see the whole actuator, and if possible its extending rod?

PS. Yes green wire is ground!

Hi,

their purpose is to move satalite dishes. I think they are built to make very slow and accurate movements. I have doubts that they are usable for our purposes.

I've doubled the voltage of my 12V actuators to get some more speed. But if the rated voltage is 36V already, like your ones, there is not much space left for tuning, I think.

No, you cannot do that. The -12V connection at the ATX psu is not capaple to deliver the same current as the +12V one. Just a fraction.
Look in the specs of your psu!

Hello Thanos,

Actually a friend came across it (I don't know where), and thought of me. When I saw it, I thought it was used to move a satellite dish or sth.

I went home on lunch break to try and power it, the printer power supply I had was 30v/0.4A.

It worked fine but pretty slow, about 2 minutes to complete the 40cm rod travel.
I then inversed the polarity and tried it in reverse, worked fine as well

Do you know why it's so slow? If I powered it with 12V, it would be even slower, right?(I'll try tonight)
would it be any good for motion sim?


So, if I understand right, the good point about this actuator is that compared to that schematic

I don't need the little green pcb between the avr and the motor?




how much do you sell these AVR1.5?

Thanks for your help.

Calle.

Yes I don't think it'll be fast enough.
Guess, I just have to read all the topics about actuators to find the best compromise.

thanks for your help.

No, for sure.

They are that slow because of the internal gearing. They are made to be slow in order to make small steps in dish positioning. 400mm/2min is round about 3mm/s.
Just in comparance: my acutators are 80mm/s ones if overpowered with the double voltage and they are not really fast. The frex ones are 400mm/s and the Force Dynamics ones even round about 600mm/s.

Thank you christian,
so basically nothing good under 800 eur for 2 scn5?
i still hope to come across a super diy solution, where you canibalize an old device, I was looking for garage door motors....maybe in big old printers?

as for this slow actuator, I tought of using it to pop up a tft screen from behind a small cabinet....(problem is, the actuator rotates.

anyway, thanks for the support, to thanos too, i read a lot of your posts, I see you're doing a lot for the motion sim community. :clap:
