Allen-Bradley MPL-B310P-MJ72AA Inverter Duty AC Servo Motor

MPL-B310P-MJ72AA is a 460 VAC, 18.6 kW MP-Series MPL low-inertia inverter-duty servo motor from Allen-Bradley, designed for precise, high-speed motion control. This 100 mm frame size motor features a 25.4 mm stack length and a rated speed of 5,000 rpm, offering compact, high-torque performance for automated machinery. It uses a multi-turn high-resolution encoder for absolute position feedback and provides a shaft with a key (no shaft seal) for reliable coupling, along with circular DIN connectors that are right-angle and rotatable 180°. The motor mounts to an IEC metric flange and has no integrated brake, with a continuous-duty (S1) rating suitable for all-day operation. As part of Rockwell Automation’s Kinetix MPL line, it’s intended for inverter-drive servo applications such as CNC tooling, robotics, packaging, and automated assembly where fast response and precise positioning are required.
