During our time at AHR 2018, we walked around and talked to some of our great partners.
Baldor, an Arkansas-based industrial electric motor manufacturer, offers AEGIS® Rings in several product lines:
End-users can buy off-the-shelf motors equipped with a pre-installed AEGIS Bearing Protection Ring. Other motors have an option to install AEGIS at the Baldor MOD-Express department. Baldor also manufactures drives, mechanical power transmission products, and generators.
We spoke with Tyler Lensing, Assistant Product Manager, at the AHR Expo. Here’s what he had to say:
TECO-Westinghouse Motor Company is a world leader in manufacturing electric motors and generators, and rightly so. The Westinghouse brand has been around for over 125 years! TECO-Westinghouse offers a broad selection of motors, ranging from 1/4 HP to 100,000 HP.
We met also visited their booth during AHR 2018. There are four TECO-Westinghouse motor lines that feature AEGIS® SGRs as an option:
With its headquarters in Round Rock, Texas, TECO-Westinghouse Motor Company serves the petrochemical, electric utility, pulp and paper, water/wastewater treatment, air conditioning, marine, mining, and metals industries.
Another one of our motor manufacturer partners, US Motors/Nidec, exhibited at AHR 2018 near us and we paid them a visit.
VariTough® Inverter Duty Motors are designed for commercial condenser units operating on VFDs. These motors operate in a multi-motor environment with one VFD. The motors are designed to meet NEMA MG1-Part 31 design guidelines.
VariTough motors offer an effective solution to protect the bearings where shaft voltage discharge may be an issue. Each motor has an AEGIS® SGR Bearing Protection Ring mounted on the motor. The SGR provides charge on the shaft with an alternative path to ground, a safe path that doesn’t lead through the bearings. The ring is factory-installed on the VariTough motors and is also sold separately as an accessory kit. See this brochure for additional information.
Walking around AHR 2018, we had a chance to catch up with our friends at WEG. Todd Wimmer, VP of Sales, was kind enough to make a video with us about AEGIS® Shaft Grounding Rings, why they’re necessary, and how WEG motors are available with AEGIS Rings pre-installed inside the motor:
Recognizing the need for long-term bearing protection on inverter-duty motors, WEG Electric Corp. was one of the earliest OEM adaptors of AEGIS Bearing Protection Rings.
These motors are inverter-duty rated, with Class F insulation, Class H impregnation resin and magnet wire, and AEGIS Rings installed internally. Internal installation protects the rings from contamination so they can keep the bearings protected no matter how severe the environment outside the motor is.
AEGIS Rings are available factory-installed inside the following WEG motors:
All of these motors are specifically designed to provide maximum ventilation for cooler operation. Sizes 254T and up have cast-iron frames with regreasable ball bearings. Other sizes have rolled steel frames with permanently lubricated ZZ ball bearings. AEGIS Bearing Protection Rings are internally installed as a standard in motors up to 100 HP for RPM ratings of 1800 and 3600.
AEGIS Rings may be installed on other WEG motors upon request.
