Introduction: How to Find Stepper Motor Coils Easy and Fast

First you must find how a stepper motor work and for that i have a video for you.

You whill find all you need about stepper motor.

Step 1: Now ...How to Do This..

Now take Meter + and connects to a wire of the stepper motor now whit the -- coneect to the other 3 wires stop when you have a resistance you have the first coil ,now check the two wire who remained you must have the same resistance ,now you have 2 colis .

Here you can see that the first two random wires measured open, and
the second two measured 1.8 ohms. This is a typical large-ish 2 phase stepper.

Is it possible to make these stepper motors to work like continuously turning regular DC motors, if yes how? Anyone knows?

Sorry, but this needs more work as the meaning is quite unclear. It also doesn't mention polarity, but I guess that's what the referenced video is for.

I wonder if one of those AVR RLC/transistor testers could do this? They'd need four active terminals to identify the coils, but I think they only have three. Should be easy enough to rig up 4 analog inputs of an Arduino and write a program to identify the coils by continuity (but what of the coils polarity?).
