Here at Precision Zone, we use specialized test equipment for a full evaluation of motors and their performance. With these tools, we are able to obtain a complete analysis of the motor’s health.  With just a quality multimeter, a reduced test can be performed to try and identify any major issues with the motor’s windings. Typically, a milliohm and megohm meter are the recommended tools of choice for field evaluations but a multimeter can work as well.

  • Power off machine
  • Clean motor terminals/pins being checked
  • Look for high resistance or open circuit readings between each phase and ground
  • Measure resistance between phases. The variance between the corresponding phases should be under 10%. Resistances should generally be under 2Ohms of resistance.
  • These tests help identify significant problems with the motor.
