There is something magical about motors , even worse, stepper motors..You just cannot throw them away. Even a dead one can be a good source or magnets.
I have this Sankyo 5-pin stepper. I do not remember whether I took it from a large hard drive or a printer. But it is time to find a job for this handsome rotator.
But first I must identify the pins. Web search did not give much except one guy who posted it for sale on almost every website you can imagine.

The motor has 5 pins, colors were in sequence RED- YELLOW -ORANGE -BLACK- BROWN as shown in the picture.
the resistance measurement matrix is shown below together with my interpretation of how the coils are arranged inside.
I plan to first try to rotate it by feeding a ULN2003 driver IC from a CD4017 counter and wish me luck.
If anyone has any comment or correction, I will be thankful.
