Regal-Beloit was one of the many exhibitors at AHR 2018. Several of Regal's brands feature AEGIS® Bearing Protection Rings to protect the motor bearings against electrical damage caused by VFD control. We talked with Chris Reid, Product Market Manager, about Marathon Motors in particular.

LEESON Extreme Duck Ultra
LEESON's lines of Premium Stainless Steel motors and Extreme Duck motors, through 2 HP, now include motors with internally mounted AEGIS Shaft Grounding Rings. SGRs are needed in applications where motors are controlled by inverter drives, to eliminate the voltages that may damage the motor’s bearings.
Features include:
- Premium stainless and Extreme Duck series
- 1/2 HP to 2 HP
- Eliminate bearing currents from inverter use
- Provide longer bearing life
- AEGIS Shaft Grounding Ring installed internally
EXTREME DUCK ULTRA IS ONE TOUGH DUCK: The revolutionary new design of this motor ensures that liquids won’t penetrate the motor in any mounting position, and made the motor a bronze winner in Plant Engineering’s Product of the Year. Plus it’s easier to install and connect because of unique non-wicking colored leads. Less corrosion, less operating costs. AEGIS Rings are available as an option for ½ to 2 HP.
Century Electric Motors
Century Electric Motors are also available with factory-installed AEGIS Rings. If you plan on running your new Century motor on a VFD, be sure to request a factory-installed SGR.
