Hey, I am going to make my own version of the cagey clown Cagey The Clown With Animated Girl Prop and need a motor for the girl. I will use a doll so there would not be much weight.
I plan on using a wiper motor for the clown but it is too heavy for the girl.
Most motors are much too fast for anything you would use on a prop. That is why they are geared down. Then, the question is how fast, and how much force do you need. A cheap toy motor that is running off of an AA battery is easily capable of moving a 100 pound load.... but it will have to do it very slowly. At the same time, a $200 1 horse power AC motor could be to weak for the same 100 pound load, if it is not properly geared.
And "as fast as possible" should be translate to "as fast a necessary, with the amount of money I am willing to spend".
Sorry, I overlooked the message with your link to the clown prop. I would think that a windshield wiper motor would be good for something like this. And since they are commodity items, they are very cost effective. Can you move the motor somewhere else, so the weight is not where it is a problem? Perhaps into the Clown's body, then link the motor to the doll with a rod.
I use the wiper motors verry often also. I was going to use the wiper motor for the clown side to side motion and a separate motor for the girl motion under her dress. The wiper motor for the clown will be on top of where the waist is.
I would go with the wiper motor, they run just shy of 60 rpm unless you run them at a slightly higher voltage. I would find a way to add support to the girl doll like metal rods or PVC to make the girl support the weight. If you believe the motor is still to heavy, comb through ebay. I can usually find unique motors on there. One other place I can recommend is surpluscenter.com. Lots of surplus motors.

Subject basically says it and I'm looking for one. We all know those light-holders we can install on our roofs and gutter basically meant for string lights and such but I'm planning to do mine with 1/2" rope lights....so....anyone know of a fastener made specifically for those OR does anyone...
Hi all - figured I’d carve out a place to post build progress and details on a motion simulator I’m building. I love the idea of a dark ride but don’t have time or space to build a track etc. I’ve seen variations on this idea on the forums, but haven’t seen one completed.
Originally I was...
