Cooling Tower Direct Drive System
In order to provide cooling towers with greater reliability and effi ciency, WEG developed the Cooling Tower Direct Drive System to replace conventional cooling tower ventilation systems formed by motor, driving shaft and gearbox reducing mechanical losses, which enables higher performances.
The rotor of the Cooling Tower Direct Drive features permanent magnets which ensure high performance levels withhigh torque, even at low speeds. This new motor, since it does not require a gearbox, eliminates tower water contaminationby the gearbox oil and presents great advantages to the system, such as lower consumption with the air fl ow control, fewershutdowns for maintenance and lower noise.
Benefi ts
Greater power effi ciency Greater coupling effi ciency Greater safety and reliability Less noise Less maintenance Reduction of mechanical losses by eliminating gearbox and driving shaft
The conventional tower ventilation system requires more mechanical repairs due to:
Gearbox faults Oil contamination and leaks Mechanical misalignment Excessive vibrations
