The MPL-B420P-RJ74AA is a low-inertia, high-output brushless servo motor from the MPL series by Allen-Bradley/Rockwell Automation. It features a compact design that allows it to fit into tight spaces while delivering high torque for demanding applications. The motor is enclosed to protect against solid particles, and with an additional shaft seal, it can also be safeguarded against liquids. It's important to replace the shaft seal periodically to maintain this protection.
The motor includes a 2-pole resolver for accurate position feedback, which is crucial for precise calibration of rotation speed. It operates at 400 Volts and has a frame size of 115 millimeters. The motor uses permanent magnet technology with rare-earth magnets arranged in a 2-inch long stack. These magnets play a key role in adjusting the motor's speed and acceleration during operation. Additionally, the MPL-B420P-RJ74AA comes with a rotatable connector for easy installation and a shaft key for added protection, although it does not come with a built-in shaft seal.
