More data please. Exact model number of motor is useful.
If no data available, I would try to put 5V current limited to 50-100mA on Black (0V) and Red (+5V).
Then I'd try to turn it slowly while watching the other leads with a scope. And I would expect to see a 2 phase signal on two of them, and an index signal on the third. Let me guess the white is index. |
