The MPL-B520K-SJ74AA servo motor is a high-performance servo motor. It is manufactured by Allen-Bradley and it is part of the MPL series of servo motors which are compatible with the Allen-Bradley Kinetix servo drives. The rated rotor speed of the MPL-B520K-SJ74AA servo motor is 3500 RPM and the maximum rotor speed is 4000 RPM. The motor torque ratings include 10.7 N-m of continuous torque and 23.2 N-m of peak torque. The power output of the MPL-B520K-SJ74AA servo motor is 3.5 kilowatts. The MPL-B520K-SJ74AA servo motor is designed for 400 Volts of input voltage. The frame size of the motor is 165 millimeters and the magnet stack length is 2 inches. The motor shaft has a key but not a seal. The motor housing has a protection rating of IP 50 when it is mounted with the shaft pointing upwards. The protection rating increases to IP 51 when it is mounted with a horizontal shaft and it increases to IP 53 if the motor is mounted with the shaft pointing downwards.

Another way of increasing the environmental protection rating of the Allen-Bradley MPL-B520K-SJ74AA MPL series servo motor is to install a shaft seal kit on the servo motor and to use sealed cable connectors. If this is done, the environmental protection rating will increase to IP 66. The MPL-B520K-SJ74AA servo motor features a holding brake with a 24 Volts DC voltage rating that weighs 12.38 kilograms. The motor power connector for this servo motor is a circular DIN connector. This power connector can be rotated up to 180 degrees in either direction. The motor also features a 1024 sin/cos absolute single-turn encoder for feedback. The motor is flange mounted and it has an IEC-metric flange as part of its housing. The MPL-B520K-SJ74AA servo motor weighs approximately 9.8 kilograms.
