Product Overview
The ABB BSM90C-375UAX is a high-performance 3.3kW brushless AC permanent-magnet servo motor from ABB’s Baldor-Reliance BSM C-Series, engineered for precision motion control applications requiring exceptional dynamic response and torque density. As part of the BSM C-Series, the ABB BSM90C-375UAX is specifically designed to handle higher load inertias while maintaining compact dimensions, making it an ideal choice for machine builders seeking responsive, reliable performance in space-constrained industrial designs. The ABB BSM90C-375UAX delivers a robust 22 Nm rated torque with a peak capacity of up to 60 Nm, enabling demanding acceleration and deceleration profiles essential for high-speed automation tasks.
The ABB BSM90C-375UAX features a 90mm square IEC flange mounting configuration and is available with either resolver or high-resolution absolute encoder feedback options, providing precise position and speed control for closed-loop servo systems. The ABB BSM90C-375UAX is rated with an IP65 protection class, ensuring reliable operation in environments exposed to dust, coolant mist, and occasional wash-down—a critical advantage for food processing, pharmaceutical, and converting applications. The built-in PTC thermistor provides direct winding temperature monitoring for enhanced thermal protection. The ABB BSM90C-375UAX typically operates with ABB servo drives such as ACSM1, MotiFlex, or MicroFlex platforms, delivering the high bandwidth and torque response required for electronic cam, registration, and positioning axes.
