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 heat exchangers.

Reduced maintenance

Eliminating gearboxes, belts and pulleys reduces maintenance points, minimizes downtime and significantly lowers long-term service costs in air cooled heat exchanger applications.

Space-saving

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

Quiet operation

A gearless design reduces noise and vibration, making direct drive motors ideal for cooling towers near occupied buildings, data centers and urban environments where low noise is critical.

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.

Energy efficient

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

Simplicity

Direct connection of the motor to the fan reduces system complexity, easing installation and simplifying long-term maintenance and service.
