Motors with AEGIS® bearing protection ring INSIDE
The General Purpose TEFC line is composed by W01 and W22 motors.
W22 is a motor with cast iron frame designed to provide significantly lower energy consumption, maximum ventilation, heat dissipation and low vibration and noise levels.
These motors are supplied with Aegis® bearing protection ring to avoid current flow along the motor shaft, across the bearing and return to the frame thus preventing premature bearing wear and failure due to electric currents flowing through them.
