Why We Test For Shaft Voltage (And You Should, Too!)

Bearing discharges damage the motor bearings in two ways: the degradation of the bearing grease the roller assemblies are suspended in, and by electrostatic machining (ESD) of the bearings and bearing raceways. The combination of the two can be devastating to the life of the motor bearing and should be mitigated to avoid costly repairs and machine downtime.
