Hey guys, I picked up two rotating solenoids at a surplus store recently and I haven't the slightest clue on what voltage to use. I googled the Serial Numbers but these solenoids seem to not be very common. Should I just try random voltages , do I run the risk of damaging the solenoid? Also how can i get a power supply that has variable voltage?

I would advise a slowly increasing voltage, starting from 0. The solenoid should operate at about 2/3 of its normal driving voltage. It may be rated only for momentary actuation, so you should used a pushbutton to keep from apply continuous current. As long as the device is not getting too hot to hold in your fingers, you are not likely to be hurting it.
That is often called a lab supply. You buy or build it. If you have a variac, a bridge and a thumb-sized electrolytic capacitor of 24V rating, you could lash up something to apply a variable near-DC voltage to your solenoids, so long as you take care not to electrocute yourself or blow up the cap.

Google
http://www.solenoids.com/rotary_solenoids.html
to see whether you can find specs for you solenoids there.
Once you've decided on what range of current and voltage you want for
the power supply you can try ebay or Google for it.
I saw the picture and I'm not sure what they're for and I'm guessing instead of a plunger the shaft rotates? Please explain and their general applications and why? tnx
