Allen-Bradley MPL-B420P-MJ22AA Servo Motor

Allen-Bradley MPL-B420P-MJ22AA is a high-precision MP-Series servo motor rated for 460 VAC operation, delivering 4.74 Nm of torque at up to 5,000 rpm within a compact 115 mm frame and a 2-inch magnetic stack, making it well-suited for medium- to high-speed rotary positioning in automated machines. It uses a multi-turn high-resolution encoder for accurate position feedback and features a shaft with a keyed output and a circular bayonet connector facing the shaft; the model has no brake and uses an IEC metric mounting flange for easy integration into standard machine frames. The unit weighs about 8.99 pounds and offers installation flexibility with free mounting holes (Type FF) and a right-angle, 180-degree rotatable bayonet connector, supporting flexible orientations. Note that MPL-B420P-MJ22AA is listed as discontinued by the manufacturer, but remains available through certain distributors; verify drive compatibility (Rockwell MPL servo drives or MP-Series controllers) and encoder specifics with the supplier to ensure it meets your system requirements. This motor is designed for precise rotary motion control in automated manufacturing, packaging, and machine tooling applications, where reliable torque at a steady speed supports accurate positioning and repeatability in closed-loop control.
