Stepper Motor as a 'normal' motor
Hi, I recntly took apart a hard drive and there is a 7200 rpm motor inside. Only problem is that it is a stepper motor and I don't have any equipment to drive stepper motors and buying stuff to do is err... cost prohobititve. Would connecting a negitive wire to 2 of the terminals and positive(in sort of a crisscross pattern e.g. -+-+) to the other make it run like a regular motor? I just don't want to invest time to solder it only to have it not work.

Wait... that's a stepper motor? No wonder it didn't work with all of my experiments... I should have known that...
No, it doesn't work. You need some type of controller

Are you sure its a stepper, it might be a three phase Brush less motor. thye also have 4 wires, where 1 is gnd and the three other are phases

You need a controller for a stepper motor.
In the basic form it is a H-bridge but since you ttok the drive apart there should be a controller on the circuit board.
