Greetings. I got an unidentified 6-wires stepper motor, which i suppose is unipolar. But, the motor drivers i have is for bipolar ones. As i understand, a bipolar driver can drive a unipolar motor, by plugging in the ends of the coils and leaving the middle wires hanging. Is it that simple or are there some caveats? Second problem, how can i identify which wires do what? There are two trios of interconducting wires, in each one there is a pair that gives the most resistance on rotor when shorted, but when i plugged these two pairs, the motor does not work in a consistent way - either vibrate in place or starts moving back and forth. i tried swapping one pair and different step rates to no avail. What can be wrong?
