Hello All,
I have scavenged 2 motors from old hard drives, but I am unclear on exactly what type they are. They each have 3 leads, the center seems to be a common pin. When I apply voltage across pin 1 and 2 (counting from left to right) the motor rotates maybe a 12th of the way around in the one direction, if I apply voltage across pings 2 and 3 it rotates the same amount in the opposite direction.
I beleive this makes them stepper motors, but I am unsure whether this means they are unipolar or bipolar. I have attempted to read several tutorials on stepper motors but none seem to mention 3 lead motors.
Can anyone help me figure out which type I have and give me a general idea of the sequence the leads should be energized in inorder to cause it rotate fully in either direction
I'd like to eventually use them in a robotics project, perhaps free moving or line following robot.
