Reusing Stepper Motors
Over the years I have collected many useful looking stepper motors, now it is time to start using them!
| Common stepper motor configurations have 4, 5 or 6 wires corresponding to phases wired as follows: | ||
|---|---|---|
 |  |  |
| 4 wire bipolar stepper motor | 5 wire unipolar stepper motor (unipolar drive only) | 6 wire unipolar stepper motor (drive as bipolar by ignoring centre tap) |
| Less common stepper motor configurations have 8 or 9 wires corresponding to phases wired as follows: | ||
|---|---|---|
 |  | |
| 8 wire bipolar stepper motor | 9 wire unipolar stepper motor (unipolar drive only) | |
Recovered stepper motors
On the sidebar there is a list of stepper motors that I have recovered from various pieces of scrap equipment and the linked pages include basic motor specifications and connection details.
