Identifying the stepper motor phases 2 Phase nema 17 stepper motor with CE ISO ROHS Certification

Here are two ways you can pair the stepper motor wires into phases:

  1. Use a multimeter. There should be a few ohms resistance between two wires that belong to the same phase, and no continuity between wires that belong to different phases.
  2. With the motor wires not connected to anything, spin the spindle between your fingers. Short two of the wires together, then spin the spindle again. If it is much harder to spin than before, those two wires belong to the same phase. Otherwise, try again with a different pair of wires shorted together.
