In my workshop, the motor of one centrifugal fan suddenly experienced high temperatures; please help analyze this issue

Could other electrical installations be causing the imbalance in these three parameters? I suggest adding a reactor in front of the motor.

I’m not sure to what extent the current has shifted; it’s likely that inter-turn leakage and short circuits have occurred, but they are relatively mild. At this point, it’s better to stop right away, take it apart and check; if the insulation layer has deteriorated, then re-coat it with varnish. There should be no problem.

A similar situation has occurred in our workshop as well, but the current carried by each phase changes from time to time. Could three-phase imbalance be related to this kind of situation?
