MPL-B420P-RJ74AA

The MPL-B420P-RJ74AA servo motor is a low-inertia, high-output brushless servo motor that has been manufactured in the MPL series by Allen-Bradley/Rockwell Automation. This servo motor has an innovative design that enables it to fit in almost any space but it can still provide high torque and operate in applications that require high torque capabilities. This servo motor comes with an enclosure that protects it from solid particles. When a shaft seal is installed, it is also protected from liquids. The shaft seal must be replaced periodically to ensure that the servo motor is always properly protected during operations. The Allen-Bradley/Rockwell Automation MPL-B420P-RJ74AA low-inertia, high-output brushless servo motor includes a 2-pole resolver for providing feedback about the position of the motor. This resolver is important since the motor needs to detect its position accurately so it can calibrate its rotation speed correctly.

The Allen-Bradley/Rockwell Automation MPL-B420P-RJ74AA MPL series low-inertia, high-output brushless servo motor operates with a voltage rating of 400 Volts and it has a frame size of 115 millimeters. This servo motor operates with permanent magnet technology and it has rare-earth magnets in its motor. These rare-earth magnets receive the current that is used to perform changes in the speed and acceleration ratings  of the servo motor throughout the application process. The magnets inside the MPL-B420P-RJ74AA brushless servo motor are arranged in a magnet stack that is 2 inches long. The Allen-Bradley/Rockwell Automation MPL-B420P-RJ74AA low-inertia, high-output brushless servo motor also comes with a rotatable connector that makes installing the servo motor easy. This motor includes a shaft key that provides protection even though it does not have a built-in shaft seal.
