I am using ULN2003 to run Mitsumi M35SP-9 stepper motor salvage from old injket printer. The motor is 5 wire unipolar, with 24 V and 7.5 Deg step. so it's 48 steps per revolution.
The problem is than I operate it on 12 V instead of 24 V and instead of 48 step it rotates full turn at 12 steps. I havn't check it on 24 V. other 12 V stepper motors are working properly.
What is the problem ?
Regards.
