By Tom Bishop, P.E.
EASA Senior Technical Support Specialist

The most frequent concern about high current with a three-phase motor is high no-load current. But the broad issue of high no-load current isn’t the only three-phase motor issue to which plants should pay heed: High current with load and lower-than-expected no-load current are potential areas of concern, too. This article published in Plant Services explores the sources of all of these.

  • High no-load current: Motor not rewound
  • Motor with no nameplate
  • High no-load current: Rewound motor
  • High current with load
