Motor Bearing Current Issues

Solutions at the Drive and Motor cables Part 2 of 2 part series on Motor Bearing Current Failures As discussed in part 1, increasingly motors are operated on variable frequency drives. This often results in premature bearing failure due to bearing currents. These currents passing through the bearings can lead to damage in the form […]

Prevent Downtime with Electrical Bearing Protection

In today’s energy conscious world more and more motors are being operated with variable frequency drives.  Drives provide large energy savings, reduced inrush current and precise speed control.  However, VFDs do have their drawbacks.  Chief among these drawbacks is electrical bearing damage caused by stray shaft currents.  This damage manifests itself in the form of […]
