I have two stepper motors for sale. I was going to use them for a homemade equatorial platform but I decided to take the easy route and buy a commercial controller/stepper motor combo instead.
Motor 1. I bought this motor new from Apogee Inc. (can see it on their website). It's 12VDC, 48 steps per revolution. Shaft size: 5mm dia., 13mm length. Unipolar, 6 leads. Motor has a 10:1 gear reduction. Cost $15.00 new from Apogee + shipping. Asking $10.00 (includes shipping by priority mail).
Motor 2. This is a 12VDC, 35 ohm, Hurst stepper motor. It's Unipolar, has 6 leads, 200 steps per revolution, geared down about 30:1. Two of the leads on this motor were frayed and I had to repair them. Asking $15.00 (includes shipping by priority mail).
Thanks for looking.
