Specific controlled motor

Sounds like you need a small DC stepper motor. What's it driving? Why do you want to make it rather than just buy it off-the-shelf?

When selecting components for this type of project start at the blunt end and work backwards so spec a motor with a form factor that's suitable and sufficient power. Then work backwards by designing a controller circuit that's suitable for your motor then finally work out your components according to what's available locally.

I am unaware to find a motor that only does exactly that, I am not opposed to buying it however this presented a learning oppertunity and challange for me so now I feel I must do so. It is for a customer, I believe she is a film fenatic, she has a camera which uses 35mm film and makes a short video clip with it. It happens to be a hand crank operated device and she doesn't want it to be. Each revolution takes 2 pictures, she wante 6 revolutions a second and there are 36 exposures on a roll of 35mm film. At that ratio, 12 frames a second X 3 seconds = 36 exposures. It has to stop exactly there or it will rip the film out of the canister. Prior to calling me she decided to try a drill motor and destroyed her other camera and by the way she talks about it I can tell I am definatly not the first person she has called about this. Seems completely rediculous to me for 3 seconds of footage but hey people like what they like and she's paying.

got just the thing here:

Because its at a design theory stage it would be cheaper to buy a camera with the functions she requires, the time effort and material cost to do this would outweigh buying a mass produced off the shelf product... unless you are doing it all gratis and want to impress then Id mull over what I just said.

They do not happen to sell this particular camera with such features. I think it is a total waste of money aside from the fact that it is what she wants, shes an enthusiast as well as, I believe, financially secure so to speak so moneys not an issue at that point. It must be nice, if I had money to burn like such I would waste it in far more interesting ways as well as buy up 1/2 of the worlds firecracker industry and just throw them at everyone all day. I don't even know this broad and already have a fantastic Lover so there is no desire to impress her however I am always looking to impress myself.

Fair enough .. I do big motors so not on the level your requiring but wish you all the best in your search for a solution ... I also like the obscure projects it keeps the grey stuff ticking

Yes it does, whats going to prove more difficult is how to attach it while maintaining a nice appearance.
