- Unipolar stepper with 0.1" spaced 5-pin cable connector
- 2052 steps per revolution
- 1/16.128 geared down reduction
- 5V-12V DC suggested operation
- Great first stepper motor, good for small projects and experimenting with steppers
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 1/16.128 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32*16.128 steps per revolution = 516.096 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.
The gearing has a few side effects which are important to note. First, you shouldn't use interleaved or micro-stepping to control 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 20 RPM when powering with 12VDC and about 12 RPM on 9VDC.
