In the spring of 2009, AEGIS and L&S technicians visited the L&S Electric Wausau-North facility to compare real time functionality of the AEGIS SGR micro fibers with that of no shaft voltage protection.
The tests were performed on an inverter-driven 3 Phase, 15 HP Marathon XRI Motor.
1. Shaft voltage testing shows presence of Electric Discharge Machining (EDMing) and proof that proper shaft grounding is necessary to prevent premature motor bearing failure.
2. With the addition of the Aegis SGR™ motors will now be true inverter duty and the bearings will be capable of lasting the service life of the motor.
