Cooling Tower Motor and Drive System
The direct-drive technology motor and drive system improves reliability, reduces maintenance and saves energy in cooling towers. It combines the technologies of the laminated finned-frame RPM AC motor with a high-performance permanent-magnet salient-pole rotor design. Its fan couples directly to the motor shaft and is controlled by the manufacturer’s VS1 cooling tower drive, providing variable-speed performance and quiet operation while using less energy than similar systems. Typically, right-angle gearboxes have troublesome maintenance problems in cooling tower installations. This design can replace right-angle gearbox and jack-shaft installations in many conventional cooling towers.
