This article from the Electrical Apparatus Service Association (EASA) explores the sources of a number of three-phase motor issues. Understanding the source of the problem means issues can be tackled quickly efficiently, should they arise.
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 worth consideration. High current with load and lower-than-expected no-load current are also potential areas for concern. This article explores all of these.
- High no-load current: Motor not rewound
- Motor with no nameplate
- High no-load current: Rewound motor
- High current with load
