Baldor Electric Co.: Cooling Tower Motor-Drive System

October 12, 2009


A direct drive technology for cooling towers improves reliability, reduces maintenance, runs quieter, and saves energy, according to the company. By combining the laminated finned frame rpm ac motor with a high-performance permanent magnet salient pole rotor design, the product can directly replace the right angle gearbox and jackshaft installation in many conventional cooling towers. According to the manufacturer, the fan couples directly to the motor shaft and is controlled by the company’s unique VS1 cooling tower drive to provide optimal variable-speed performance that runs quieter with reduced energy consumption. The cooling tower drive is specifically designed to work with the cooling tower motor to provide easy cooling tower start-ups. Water ingress along the shaft is prevented with the use of a labyrinth bearing isolator and flinger, while condensation drains relieve any moisture that may collect inside the motor.
