This stepper motor is great for small projects and experimenting with steppers. This motor has 8 steps per revolution, but because of the 1/64 reduction gear set this translates to 512 steps per revolution. The shaft is flattened so its easy to attach wheels, gears etc, with a set screw.

I had the motor the next day. It could be just the thing I need. I will know when I get it powered up but I cannot see why it is not just what I need. Many thanks. I'll be back!

Cheap - but that was the pont

I used this to explore possibilities for a project without purchasing (and possibly not being able to use) a more expensive motor. I modified it to be bipolar and it works a treat with the small H bridge controller.

Cheap, low torque poor maximum step rate
Tuesday, 10 March 2015  |  Jeff

This motor is very cheap, and works well out of the box. Given the gear ratio the torque is disappointing. Also the maximum step rate is limited to about 200 Hz.
