Topic: salvaging UNI-polar stepper motors - best place to find them? (Read 474 times) previous topic - next topic


I see that most old printers an scanners have 4 wire Bi-polar steppers in them.
What devices should I look for that will be more likely to have salvageable UNI-polar stepper motors in them?
They're just so much easier to control with an Arduino because all you need is some transistors or a darlington array.


Difficult , most commercially produced equipment uses bipolar because they are cheaper in mass production once you take into account the associated drive circuits.

IME anyway
