For example, if your purchase qualifies, you could enjoy No Payments + No Interest if paid in full in 6 months on $99+. Plus with this configuration I can hear a ticking sound from the motor. The catch is that you can't just power up a HDD motor and expect it to spin... Commutations are A-B, B-C, C-A. http://tuiconverter.com/hard-disk/hard-disk-motor-driver-circuit.php
Anyway I placed a black DOT that I will refer to as terminal #1, the others from left to right are #2,#3, and #4.

The Output of the Op-Amp provides the transistor drive as well as a tach that can be monitored. Is the stepper designed with a massive magnetic core that retains lots of residual magnetism, where the hard drive motor does not? You're the high bidder, but the reserve price is not met. As far as these specific printer motors.

You're the highest bidder on this item! Some have inbuilt push-pull drivers (to drive the motor directly), others require an external three-phase bridge. The hard drive motors, in particular, are extremely smooth-running, and I wanted to see how to drive them.
