This is a great first stepper motor, good for small projects and experimenting with steppers. This uni-polar motor has a built in mounting plate with two mounting holes. There are only 32 step (11.25 degree) per revolution, and inside is a 1/16 reduction gear set. (Actually its 1/16.032 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32*16.032 steps per revolution = 513 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw. A perfect first stepper motor and works well with the Motor Shield for Arduino.
Do not?use interleaved or micro-stepping to control this motor or it will take forever to turn. Instead use single or double stepping. The torque is fairly high but its slower than un-geared steppers – we maxed out at about 50 RPM by over-driving it a bit with 9VDC. At 5V try to stick to under 25 RPM.
You must?use this motor with motor driver board/ IC to get it working, ULN2803 IC works great with this motor. Check out the ULN2803 Motor Driver board in out Store.
