Thread: How to Slow Down a Wiper Motor...

Tweet

So I'm running a flying crank ghost off of a wiper motor. My problem is that when I use a 9 or 6 volt adaptor with the motor it either jerks, or doesn't have enough strength to pull the ghost.

A 12 volt transformer works great, but the ghost looks like it's trying to break out of my house rather than move slowly.

I figure I could probably control the prop with one of the expensive devices for sale at Monsterguts, etc., but I only have two electrical props this year, and can't afford to pay too much for the effect.

Is there anyway cheap I can slow the motor down without losing power?

Figured somebody here would have to know.

Thanks.

having trouble picturing if it will do what you need but if you pic up a low risistor it should lower the power on the transformer but not so much that you will lose your effect sorry I can't give you an ecact number right now but if I figure it ou tI wil let you know

are you sure your power packs are producing enough current at the lower voltage to run your motor ? The standard 5 volt power packs that Monster Guts sells with their wiper motors works perfectly. I am using one on my grave grabber and it runs as smooth as glass and has enough power to rip his arms off if need be...

It sounds like your power supply is not supplying enough amps, whats it rated at? Your going to need at least something that outputs 4-5 amps. Like Diabolik said MG offers 5V 5A supplies. Remember wiper motors are akin to starter motors i.e. high torque motors and require more ampers. Hope that helps.

As for cheap, MG seems to offer the cheapest solution... you can find tons of 5-12V supplies but offer only .5 to 1000mA, not big enough.

I use these supplies:
5VDC 3.7A SWITCHING POWER SUPPLY | AllElectronics.com
Works great, plenty of torque, good price.

I agree. The power supply isn't providing enough current. You might want to take a look at All Electronics web site for wall transformers and power supplies. They often have 5v and 9v power supplies with 2-4 amps of current.

Bingo! Great minds think alike (that's my story and I'm sticking to it)!

Awesome! I'm ordering one today. Seriously love this communal site. And really appreciate the help. I've learned a ton from the folks here, and have set up a pretty fun home haunt. The kids and neighbors are all really excited.

Happiness to all

I am also having the same problem. Someone told me to use an old laptop power pack. Last night I hooked mine up to a dc wall mart and thought this FCG boogies. It looked like it was having seizures.

Are they supplying the 3.7a, people in the review section are saying they are seeing 1.5a? If the really do put out 3.7a, they maybe worth while for sure.
