The Highest Efficiency at Every Operating Point
The FANWALL® Ultra-Premium Efficient motor is a cutting-edge brushless permanent magnet-assisted synchronous reluctance motor, engineered for exceptional efficiency and performance. In typical variable torque and variable speed fan applications, it consistently delivers 5% to 20% greater efficiency compared to NEMA Premium® efficiency induction motors. What’s more, where the efficiency of a NEMA Premium induction motor falls off dramatically as the speed and/or load declines, FANWALL Ultra-Premium Efficient Motors maintain their high efficiency over a very wide operating range at lower than rated speeds.

Benefits
Rapid Payback: 15 to 20 Years of Lower Power Bills
Over its operational lifetime, the cost of powering an electric motor can be up to 50 times greater than its initial purchase price. This means that even modest gains in efficiency can lead to substantial energy cost savings. With the significant efficiency improvements offered by FANWALL Ultra-Premium Efficient motors, users can typically achieve a rapid return on investment—often within 24 to 36 months—compared to NEMA Premium induction motors. Beyond that point, the ongoing energy savings contribute directly to reducing the building’s operating expenses for the remainder of the motor’s life.

Flexibility
More compact than NEMA Premium induction motors, often a full frame size smaller.
Standard NEMA frame sizes allow easy interchangeability.
Available with plenum rated integrated drive that is axial-mounted or top-mounted up to 10 HP. 15HP motors are only available with external drives.
Compatible with readily available VFDs.
Reliability
High efficiency motors run cooler for increased reliability and motor life: L10 over 200,000 hrs.
Hybrid ceramic bearings prevent damage from electrical discharge.
Special locking bearing cap design and thrust washers prevents bearing precession in motor housing.
UL listed E46145.
