The use of variable-speed drives with AC motors induces electrical currents on the motor shaft. Once they exceed the resistance of the bearing lubricant, these currents discharge to ground (typically the motor housing), causing fusion craters in the bearings. Over time, these craters increase in size and number, resulting in frosting, pitting, fluting, and eventually bearing failure. This type of premature bearing failure can cost thousands of dollars in increased maintenance and lost production - we can offer a solution.
The technology is used in many motor and generator applications such as:
Not only is the AEGIS® SGR™ the world’s most effective grounding brush, it offers the longest lasting protection available.
