Motor Drive Package For Cooling Towers Eliminates Gearbox Failure

Gearbox failure on cooling tower fan applications is eliminated with an ABB motor-drive package designed specifically for such hot and humid operating environments. A traditional cooling tower drive system consists of an AC motor, a gearbox, pillow block bearings and shaft couplings to achieve the air flow required.  Any one of these mechanical components runs the risk of failure through regular daily use, together with the extreme environment. Fitting a permanent magnet motor, with variable-speed…
