WEG Explosion Proof Motors Now Offer an AEGIS Option

In less than sixty years, WEG Electric has grown from being a local Brazilian motor manufacturer to a diversified global powerhouse.  WEG has a reputation for innovation, and it's no wonder:  They invest 2.5% of their revenue in R&D. Through this massive engineering commitment, WEG is able to make motors that run cooler, last longer, and are easier to install.

You can see their investment paying off in their Explosion Proof motors.WEGxp  All of these motors are factory-tested to be sure they satisfy the UL or CSA specification for hazardous locations.  In fact, they not only meet those specifications' requirements, but exceed them.

For instance, WEG now offers AEGIS® Shaft Grounding Rings as an option inside their explosion proof motors.  Shaft grounding protects motors against electrical bearing damage caused by VFD operation.  AEGIS rings are the only shaft grounding device that can be installed inside an explosion proof motor.  While all explosion proof motors include protections against explosion, most do not have protection against stray bearing current.

You can find WEG's explosion proof motors in their catalog (pp A-114 through A-119).

WEG also offers AEGIS rings on non-hazardous duty motors.  AEGIS rings come standard inside several lines of stock motors, and can be added internally or externally as a mod to most others.

These are just two more examples of WEG's devotion to continuing improvement.


AEGIS Rings also come with a 2-year extended warranty against bearing fluting damage. No other form of protection against VFD-caused bearing damage offers a warranty like this.
