Hi to all ! I would like to hear your suggestion regarding practical use of electric piston. This are project requirements. 1.) Piston movement --> 5 cm back / forth 2.) Piston speed is regulated by impulses from arduino. There will be two impulses. One from magnetic contact and second from weig…

I think you need to explain what an electric piston is! Paul

Bah, I was thinking we gonna hack a RC engine and hook the piston rod up to a servo!

arnix: :-). You are correct. It's linear actuator.. Thank you for clearing that up! Now, what linear actuator are you designing for? I have a couple on a shelf that will each move 1,000 lbs. Specks, please or link or data sheet. Perhaps a drawing of the whole setup would help. Paul

The speed of a typical linear actuator is determined by the voltage fed to the motor, so it certainly can be controlled. Most can't go up to 100mm/s though, so you'll have to shop around or make your own. Are there any other constraints like size, weight, energy efficiency, long life, etc.?

@ChrisTenone I was thinking about solenoid too but i dont know if this can be controlled for such speed. Power consumption should be under 30W and I will use 12V / 3A power supply. @Slumpert He, he... this could be next step :-). @Paul_KD7HB @ dekutree64 my main job is to find some solution tha…

arnix: I guess that actuator / solenoid should work flawless at least 1 to 2 years. Btw. This system will be installed in factory, so there is no problem with atmospheric conditions. A. Your industrial engineer will also ask what happens when the device does fail? Lives lost? Fire? Machines de…

arnix: @ChrisTenone Btw. This system will be installed in factory, so there is no problem with atmospheric conditions. So, another commercial-enterprise-seeking-solutions-on-a-hobbyist-forum thread?

dougp: So, another commercial-enterprise-seeking-solutions-on-a-hobbyist-forum thread? My conclusion, also. Paul
