Thread: power of gear motors

Tweet

I found some gear motors online that sounds interesting but I was wondering if there is some easy for the math impaired types to figure out how powerful they are and if they would work for something like a FCG or stirring cauldron or such.anyone have any minimum power requirements for these kinda of props?
Gear Motor
Open, close or move whatever with this mighty little 3-12VDC 4RPM gear motor designed to operate a vent in a Chrysler product. Draws just 15mA no-load and stalls at 200mA. Output is via a 1/2" dia x 1/2" long sprocketed shaft.

Bro, that seems like a bit small for a FCG or cauldron, In my experience you simply can't beat a wiper motor for the cauldron, they are cheap and have lots of tourque.

THAT is wonderful post interesting to read

Ya I have a dayton for my FCG and a wiper motor for a caldron but saw these and was trying to think of some uses along that line.

You know what comes to mind is you can always create some light duty props for them.

Maybe an FCG spider, since you can literally make them much lighter than a FCG ghost.

depending on what kind of torque the motor has you may want to even create something like a dancing Faux Flame, don't know if a paper mache candelabra would be light enough . Depending on the batteries and type of fan used it could be very likely light enough to work as that particular motor. I think using small fans scrapped from desktops or scrapped game consoles would be more than light enough, silk is already light weight along with a DC LED so really between the fan and battery weight would be actually the equation.

That is what comes to mind with the motors you have.

I would be concerned that it isn't made for continuous duty.

Those motors are great for a lot of props and they have quite a bit of torque. I think it's a bit small for an FCG, though. I ordered mine from Electronic Goldmine and they are 5 RPM, continuous duty. But I saw the 4 RPM ones for sale on the Surplus Center site and their description claims they are intermittent duty. However a member of Hauntforum claimed that they used those 4 RPM motors and they ran continuously with no problems.
I've made a skeleton behind a tombstone prop that turn it's head back and forth, a skeleton "bobbing"head behind a tombstone, and a stirring cauldron for a little girl witch all using that motor. I can post pics/video if you want.

Yes please do

I don't have the pics yet, but I do have video. I just need to upload them to Photobucket.
I'll post them shortly.

OK--Here's the motor I used from Electronic Goldmine:
Super Power 12VDC Gear Motor-The Electronic Goldmine

Here's the 3 props I made with this motor:
