I am looking for some small and cheap stepper motors with <10oz-in torque. Most of the steppers I can find from my regular sources/ebay are 60-1000oz-in which is far too much for my purposes (and will almost certainly push the cost up). Does anyone know of a good source for these types of motors ? Unfortunately I would like 6 (and potentially more) of them, so scrounging from old floppy drives is not really an option.
How about this one from Adafruit?
- 48 steps per revolution
- 5-12V DC
- Weight: 77 g.
- Holding Torque: up to 27 mNm / 3.75 oz-in
I've no idea what torque a wall clock mechanism has, but I guess it will be rather low-ish. Prices equally low (from $5).
