Meeting Nidec at AHR 2018

Nidec’s Todd Gatti, Regional Manager, HVAC/R Aftermarket, and AEGIS Sales & Marketing Manager Adam Willwerth

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.

Nidec with AEGIS ringVariTough 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.
