Direct Drive Cooling Tower Fan Motor

The permanent magnet motor directly drives the fan eliminating a number of components including the gear drive driveshaft pillow block bearings and couplings and associated installation and alignment costs.

Direct drive cooling tower fan motor.

Has offered permanent magnet motors to meet our cooling tower customers direct drives requirements. The motor portion of baldor s adjustable speed direct drive cooling tower fan system replaces the conventional motor driveshaft gearbox combination. To power the fan it is now possible for a high efficiency permanent magnet direct drive motor to be coupled directly to the fan. After having the tower up for almost a full year i can tell you right now our energy bills are way less.

The same electric motor and control technology that is being used to power today s most sophisticated hybrid vehicles is now being adapted for cooling tower drive applications. The direct drive fan motor is controlled by a baldor vs1 drive with a specially developed speed control algorithm. This combination provides high torque and low speed required for these applications without additional drivetrain components. This is a type of electric motor with rare earth permanent magnets incorporated into the rotor.

The fan drive system provides the cooling air necessary to reject unwanted heat from the system to the atmosphere. The cooling system usually features cooling towers that house large fan blades. There are multiple direct drive options in which the motor directly drives the cooling tower fan. Available document languages.

The direct drive motor offers reliability with minimal maintenance requirements. A variable speed drive vsd controls the speed of the high torque direct drive motor for optimal fan operation. Our direct drive motor and variable speed drive packages for industrial cooling replace the gearbox driveshaft and induction motor typically used in industrial cooling fans. Cooling tower duty motors are specially designed for the harsh environment inside a cooling.

Use premium efficient cooling tower duty motors and include bac s comprehensive 5 year motor and drive warranty. A common direct drive option uses a permanent magnet motor. Since 2011 spx cooling technologies inc. Marley insight direct drive fan motor.

Not only does the new tower design maximize cooling but its direct drive air moving system which includes a vfd variable frequency drive fan motor provides significant cost savings on electricity adds voudouris. The direct drive also greatly reduces noise and eliminates the issue of cooling tower water becoming contaminated from leaky gearboxes. Direct drive permanent magnet motors are a newer technology available on most marley nc cooling towers. This results in less parts less maintenance lower noise and reduced risks.
