I want to learn how a floppy stepper motor works so that I can latter control it with my arduino.
What I did was to test if the motor in a floppy worked before pulling it off. I used a 5v from my power supply and tested the motor while still connected to the floppy circuit. And so it did. I even figured out the sequence required for it to go forward. So, I took if off the circuit.
The problem is that when I tried to make it work again (off the floppy circuit this time) it won't turn. And now, when I connect the 5v to the terminals that worked previously, this time all I get is that I'm short-circuiting my power supply.
Any thoughts? this probably has a simple explanation, but since I'm just learning electronics as a hobby I don't know much about it yet.
