Shorted to Ground

Posted on by Matt Passannante

A shorted to ground winding failure is a common cause of motor winding failure. A shorted to ground winding failure occurs when there is unusually low resistance in the motor caused by a degradation of the insulation within the windings. This can happen from a variety of conditions such as physical damage, contaminants, abrasion, corrosion, and overheating. If the problem is not fixed, it can cause insufficient isolation in the motor windings and conductors. In turn, that may cause short circuits and leaks. Eventually, motor failure can result from a shorted to ground winding failure.
