Indications of problems in a motor
If the resistance readings are significantly different from the motor nameplate data or a single
lead is more than a few percent different from the others, there is probably a short in one or
more of the motor’s windings. If one of the values is significantly higher, there could be
problems, such as:
1)
A loose or corroded wire nut connection.
2)
An incorrect amount of turns or an incorrect sized wire gauge used during a re-wind
job.
3)
An incorrect gauge of cable/feeder used from motor control to motor terminals
4)
Poor or incorrect solder technique used to connect phases.
5)
Phases/coil groups connected wrong.
