ABB 3GLL252233-ADM Synchronous Reluctance Motor - IE4

The IE4 efficiency rating combined with water cooling reduces heat buildup and energy consumption, delivering measurable cost savings on continuous operation. This translates to higher system availability in continuous process lines and lower cooling requirements for drive trains, especially in application segments demanding compact footprint and high power density. The 90 kW, 4-pole design in a Frame Size 250 with an aluminum frame provides excellent strength-to-weight ratio, enabling easier installation and reduced structural requirements at the motor housing. The IP55 enclosure and IC L F insulation class ensure reliable performance in dusty or humid industrial environments, minimizing maintenance cycles and extending motor life. Compatibility with 400 V, 50 Hz systems and the D connection configuration simplifies integration with existing variable frequency drives and control architectures. The IMB3 IM1001 mounting options streamline retrofits and new builds alike, while the double-ended rotation capability supports flexible pump and fan configurations. Industry context notes that SynRM solutions offer comparable torque with reduced copper loss, contributing to lower total cost of ownership in automotive, material handling, and packaging lines. In practice, engineers benefit from predictable startup behavior, robust bearing arrangements (6315/C3, 6213/HC5C3), and a design that supports demanding S9 duty cycles.
