Allen-Bradley MPL-B320P-SJ22AA Kinetix Servo Motor

Allen-Bradley MPL-B320P-SJ22AA is a low-inertia, permanent-magnet rotary servo motor in Rockwell's MPL MP-Series, engineered for precise, high-speed motion in 3-phase servo systems. Rated for 480 VAC operation, this 100 mm frame (Frame Size 3) motor features a 50.8 mm magnet stack and a 5000 RPM maximum speed, delivering about 3.05 N·m of continuous torque. Feedback comes from a 1024-sine/cosine single-turn absolute encoder for reliable position sensing, with a keyed shaft and no shaft seal. The motor uses circular bayonet feedback connectors and is designed with an IEC metric mounting flange and free mounting holes (Type FF), supporting right-angle mounting and 180-degree rotation, with facing shaft geometry. It is specified without a brake and is described in manufacturer literature as discontinued. This MPL-B320P-SJ22AA is built for high-precision positioning and torque control in automation systems that require a compact form factor and fast response, and integrates with Rockwell's motion controllers and the broader Kinetix family for reliable motion control.
