The Allen-Bradley MPL-B420P-HJ72AA Servo Motor is part of the MP-Series family of industrial servo motors developed for automated motion-control systems. It is intended for machines where precise and repeatable movement is required rather than basic constant-speed motor operation.
The MPL-B420P-HJ72AA has a 115 mm frame size and a specified weight of 4.30 kg (9.48 lb). These mechanical specifications are important when designing or replacing a motor within an automated machine.
Servo motors in this class can be used for packaging, assembly, material handling, machine tools, robotics, printing, and automated production equipment. When combined with an appropriate servo drive and motion controller, the motor can provide controlled speed, torque, and position response.
For replacement projects, the complete catalog number should be verified before installation. Similar-looking servo motors can have different electrical characteristics, feedback configurations, shaft arrangements, and mounting requirements.
