Q: Why is my 3-phase motor humming but not starting?
Published
A: A motor that hums but does not start may have an electrical, winding, bearing, mechanical or load-related problem. The exact cause cannot be determined from the sound alone.
Avoid repeatedly switching on a motor that is not starting. Proper inspection and testing can help identify the fault and determine whether repair or rewinding is required.
