    Default Monster Guts Wiper Motors...

    So I purchased two wiper motors from monstor guts, and the decription said they were slow speed, but they are way too fast for a Cauldron Creep cauldron and head movement. They have two settings of speed and slow is just too fast. Is there anything I can do to slow the rotations down somehow?

  2. Default wiper motor

    We always buy the lower speed so it is slower and yet has more push. So you may think about that next time.

    What are you using for the power supply? 12V will give you faster speed. I primarily use the 5V power supplies in order to slow the motor down to where I like it.

    I have a MG wiper motor for my cauldron creep. I hooked mine up on the slow setting, and I use a 5 VDC wall wart to run it. It stirs the cauldron at about 12 rpm. The wall wart I use is unregulated, which means it's probably getting a bit more than 5 VDC. I think if you use a regulated 5 VDC power source, you may get even fewer rpms than me.

    As for the head movement, I think the wiper motor isn't practical; it's too big, too heavy, and runs too fast. I used one of the small 5 VDC car ventmotors. The problem is, they're getting hard to find. For quite some time, there were several websites that sold these motors cheap (like $4 to $7 each), but last year someone bought out ALL of them. Now, you may find them on Ebay, but they're expensive ($35, maybe less if they're used ). Your best bet may be checking local salvage yards for a good used one.

    Yes, check out the picovolt from Frightprops.com. It will allow you to control the speed plus much more. They have videos demonstrating the device being used with a wiper motor on their site.

    I saw someone had posted a while back that HF carries a "router speed controller" that and be used to control speed. Have not tried yet.

    All the above ideals are good but....

    It gets expensive when you're buying a motor + power supply then you need to spend another $35 to $50 for a device to control the speed

    So my best advice for anyone else reading this that's thinking about the wiper motor as a cheap fix all for all props using motors...do your home work.

    Find a motor that works best without having to add on a $50 speed controller.

    Hoopah1972 do you have a old PC power supply if so you can power the motor with that....

    Voltage controls the speed of the motor...less volts means lower speed
    Amps control the torque......less amps means lower torque and wiper motors will also have a must use number of amps

    The PC power supply puts out well more amps than your motor will use (always good to have more) and it puts out ...

    12 vdc
    5 vdc
    3.7 vdc

    The 5vdc and the 3.7 vdc will slow the RPMs of the motor down to a point where you can use it for this prop....connect to the low speed of the wiper motor

    The PC power supply is regulated which means ...you get the stated voltage
    Unregulated power supplies can and do put out more volts than listed. When I test a 12v unregulated PS i usually get anywhere from 15v to 20v and unregulated 5v PS usually puts out anywhere from 9 to 12v

    If you don't have a PC power supply check thrift stores for a regulated 5vdc power supply it will say on the back if the power supply is regulated or not

    How much resistance is there on your stirring stick? If it takes a wiper motor to move it, I suggest this to control the wiper motor's speed. It is small enough that it will mount inside an ATX (computer) power supply box. It will allow your motor to use all of its torque at any speed you select.

    Right on. A number of times I have thought about building some of my own animated props and monster guts products are WAY cool, but when I add up the cost it's just too much money for everything. Plus I'd have to build the thing, with an eye to making it modular for storage. All things considered, all that's left is the pride of making your own prop. Just too expensive unfortunately, otherwise I'd be all in.
