Air Cooled Condensers

ABB Direct Drive air cooled condenser (ACC) motors are vertically oriented, shaft-down designs capable of driving very large condenser fans in utility and industrial power plants.

Direct drive reliability for large-scale power generation

ABB Baldor-Reliance® direct drive air-cooled condenser motors are engineered for vertical, shaft-down operation in large power generation facilities. Eliminating gearboxes improves system reliability, reduces noise and vibration and extends service life in critical condenser applications. These motors deliver dependable, efficient performance for some of the most demanding cooling systems in the industry.

Technical data

Vertical shaft-down direct drive motors provide reliable, long-term performance for high-inertia air-cooled condenser fan systems.

Up to 250Hp

Power range 50-250Hp (37-186kW).

VSD operated +N5350

ACS880 drive with ACC application code +N5350 provides optimized fan control for air cooled condensers.

Up to 60%

Saves energy and reduces mechanical stress on the system.

Frame FL5800

Frame size FL440 (TEAO) to FL5800 (DPFV).

Rotor IPM

Interior salient pole permanent magnet rotor for torque density and higher efficiency.

Insulation VPI

The VPI (vacuum pressure impregnation) insulation system ensures long motor life in extreme environmental conditions.

Explore the key features and benefits

ABB combines proven laminated-frame motor technology, a high-performance permanent-magnet rotor and a matched adjustable speed drive to deliver high-torque direct drive motors purpose-built for air cooled condensers.

Reduced maintenance

Eliminating gearboxes, belts and jackshafts reduces maintenance points, minimizes downtime and significantly lowers long-term service costs in cooling tower applications.

Space-saving

By eliminating gearboxes, belts and jackshafts, the overall system becomes significantly smaller, simpler and more compact.

Optimum pole design

High-performance permanent magnet (PM) salient pole design delivers high-torque with low speed direct drive cooling with reduced cost and maintenance.

Fit for purpose

Engineered specifically for vertical ACC fan installations, enabling direct mounting and reliable operation in large condenser arrays.

Simplicity

Motor shaft and mounting design allow direct fan attachment, simplifying system architecture and reducing mechanical losses.

Energy efficient

High-efficiency, low-speed direct drive operation reduces losses and lowers total energy consumption.

Severe Environment

Using a laminated finned-frame motor with VPI insulation, oversized bearings and protective enclosures (DPFV or TEAO), the motor resists moisture, dust and extreme operating conditions.
