Distributer for motor components?
Distributer for motor components?
(OP)
I'm working on a project where I need to fit an electricity generating device (some type of motor) in a low profile enclosure (less than 1 inch thick). Below is a picture of a Radioshack Crank Radio taken apart. Inside, to the left you can see a metal cylinder. There's two half circle magnets attached to the inner circumference of the cylinder and the cylinder is spinning around a stator with coils.
The thickness of the stator + cylinder is about 1/2 inch.
If I removed the stator/cylinder combo from the Radio, soldered it to my own PCB and attached the crank directly to the cylinder without the gears, I would have a device that is about 3/4 inch thick. Perfect for my application.
Is there a distributor from which I could buy these types of parts? ... or are they custom made?
More Details:
The stator coils would solder onto my custom PCB with rectifying ckt + voltage regulator + charging ckt for a cell phone battery.
Thanks for reading!

RE: Distributer for motor components?
the gear train might also help support the load cranking it places on the handle. If you don't like gears, then what about a belt?

If you are only making one or two units, look for crank operated LED flashlights.
Bicycle generators may be useful.
If you need a lot, consider designing your own. Increasing the diameter has functional advantages if possible.

RE: Distributer for motor components?
Are there any good information sources for designing these types of generators that I could look at for info? Maybe some reference designs? I was hoping I wouldn't have to build my own (because of the extra work and im lazy lol) ... but looks like I don't have a choice. Any help would be appreciated. I need to crack open my physics books...
