View Full Version : college project help...which stepper motor?

05-05-2007, 12:15 AM
I am working on a design project and i need to use a stepper motor. i have basically no experience with stepper motors. The device is to be battery powered and small enough to fit in one's pocket.

This is the setup i was thinking of using. i would like to power the stepper motor with an additional small battery. i dont know which one to use. i was hoping i could use a standard 9 volt or something smaller to power the stepper. BTW, the motor does not need much torque at all.

Does anyone have any ideas or comments?:?:
