Water-cooled motors deliver high efficiency
Available with induction, synchronous reluctance (SynRM) or permanent magnet rotor technology, these water-cooled motors can achieve high-efficiency (IE3-IE5) ratings for energy savings, and the power-dense designs deliver more power in a smaller footprint than similarly sized totally enclosed, fan-cooled motors. The HydroCool XT (photo) is available in four NEMA frame sizes and ratings from 60 to 1,250 hp. The M3LP has IEC frame sizes 280–500 with ratings from 120 to 2,700 hp. Cooling efficiency is maintained even at low speeds, allowing for direct-online or variable-speed operation without derating or power loss. The water-cooled motors are equipped with provisions for the company’s Ability Smart Sensor condition monitoring for instant motor health and performance information, providing connectivity and data analytics to make operations efficient, predictable and safe. — ABB Motors and Mechanical, Inc., Fort Smith, Ark.
