Variable Frequency Drives are becoming more and more popular amongst motor control applications. This is largely due to their ability to reduce energy costs and motor stress. But, did you know that your VFDs could be producing unwanted voltages across your motor? Induced voltages on the shafts of your motors can cause damage to the bearings, like pits and burnt grease, causing motors to fail.
With AEGIS® Shaft Grounding Rings, your motors can be protected against these unwanted induced shaft voltages. These grounding Rings redirect the induced voltages and ground them on the motor properly, as opposed to through the bearings which can cause harm.
