Hi,
I got a motor from an old cd-rom drive, wich i think is a stepper motor. the problem is it has only 3 wires (3 coils?) to control it and the 3 coils are conected together at one point.
I have searched around but found no usefull information.
Does anybody know how this motors work?
Thank you

it's a three phase switched reluctance motor requiring complex angle sensing. which implies it's better to look for some other device to play with.

thank you for your reply.
no wonder it has what i believe are 3 hall effect sensors.
