Stepper Motor Related Questions - Help

[Otto38]

Hello, I salvaged some stepper motors from several old printers (https://www.oyostepper.es), but their wiring colors don't seem to match any known specifications I can find. Is there any easy way to determine the correct order in which to connect them to a motor controller like the L293D?

The motor in front of me has four wires: orange, black, yellow, and brown. I feel like I've tried all possible combinations and tested them in the Arduino's stepper_oneRevolution program, but most of the time the motor vibrates and jitters uncontrollably. I know these wires should be paired in pairs, but which pins in this program correspond to which two pairs of wires on the motor?

Hopefully this question is helpful!

Двигатели разбирались? Могут из-за этого перестать нормально работать.

А обмотки предварительно можно мультиметром определить.
