RIB COOLED MOTORS

Rib cooled motors offer easy configurability and built-in serviceability throughout the product life cycle.

HIGH POWER DENSITY AND EASY CONFIGURABILITY

High voltage rib cooled motors combine compact design with high power density, delivering excellent reliability, efficiency, and ease of maintenance. Designed for long-term performance, they offer flexible configurations and built-in serviceability throughout the entire product life cycle.

Rib cooled motors are available for both direct-on-line (DOL) and variable speed drive (VSD) operation for an even higher levels of energy efficiency.

 

Rib cooled motors provide a high efficiency solution across a broad range of applications and industries. Typical uses include pumps, fans, blowers, compressors, conveyors, saws, and mills. They are widely deployed in demanding sectors such as oil and gas, mining, water, metals, chemical, and pulp and paper.
