Hi Every one
So today i disasembled a Computer Hard Drive and in side it has a motor that has a great way of attaching things to the head/horn.
It has three pins and when i apply power to it it reacts the same as a stepper motor. so i am thinking it has similar workings and internals as a stepper motor. It has no identifier markings or any thing.
I dont plan to use it for propoltion and i dont yet have plan but i hope to connect it to some sort of mechanism.
Thanks for your time

Read that post.
Basically its a brushless DC motor, which means you need a controlling circuit for it, and yes, it is much like a stepper motor, in that you have to apply power to one pair of wires, then the next etc.
Here is a diagram of a brushless motor from http://www.mpoweruk.com/motorsbrushless.htm (http://www.mpoweruk.com/motorsbrushless.htm):
