Bearing damage in electric vehicles

Engineered with conductive microfibers the Aegis SGR Bearing Protection Ring channels currents to ground bypassing the bearings entirely Scalable to any motor regardless of shaft size or horsepower the ring has been used on motors powering pumps fans turbines and conveyors in

What Works

2010-12-8The "something else" was the Aegis iPro bearing protection ring manufactured by Maine-based Electro Static Technology (EST) By channeling harmful electrical currents away from bearings to ground the iPro can extend the lives of medium-voltage motors and generators thus improving the reliability of entire systems in which they are used

EST publishes Shaft Grounding Ring Motor Repair

2013-3-15A new 36-page color handbook—the AEGIS Shaft Grounding Ring Motor Repair Handbook—describes best practices for protecting motor bearings from electrical damage Available from Electro Static Technology (EST) manufacturer of AEGIS shaft grounding rings the book explains how to diagnose electrical bearing damage caused by variable frequency drives (VFDs) also known as

Case study: Shaft grounding proves essential for

Energy-saving technology must be sustainable to help reduce these costs In the case of VFDs to bank cost savings from their reduced energy usage users must protect the bearings of motors controlled by the VFDs with proven long-term maintenance-free shaft grounding such as that provided by the AEGIS SGR Bearing Protection Ring

Shaft Grounding Rings

The shaft grounding ring is placed near either end of the shaft (see Figure 2) The carbon fiber brushes attached to the ring contact the shaft The brushes now become the easiest path to ground for current running through the shaft The current no longer passes through the bearings which eliminates bearing failure caused by the unbalanced PWM

New Shaft Grounding Ring Handbook for Best

AEGIS Bearing Protection Rings channel VFD-induced bearing currents safely to ground Continuous circumferential rows of conductive microfibers embedded securely in the ring's patented AEGIS FiberLock channel completely surround the motor shaft and provide millions of discharge points for harmful shaft currents

Bearing Current Damage

Shaft grounding rings are also sold to manage the circulating currents in the motor and ensure that the current bypasses the bearing and goes straight to ground thus preventing damage to the bearing They are mounted around the shaft and bolted to the stator housing (see Figure 2)
