MPL-B4530F-SJ74AA

The MPL-B4530F-SJ74AA servo motor is a brushless servo motor from Allen-Bradley/Rockwell Automation. The servo motor is shipped with standard control functionalities from the factory which include an IEC metric mounting flange. The MPL-B4530F-SJ74AA servo motor comes fitted with a brake to hold the motor’s shaft at a speed of zero revolutions per minute when it has been powered down. Note that the holding brake is a spring-set holding brake that disengages when a voltage is applied to the brake’s coil. The MPL-B4530F-SJ74AA servo motor belongs to the Allen-Bradley MPL series of motors with low inertia. The MPL-B4530F-SJ74AA servo motor contains a shaft key but no shaft seal. However, when the servo motor is likely to be exposed to liquids and fine dust, a shaft seal can be purchased and fitted separately.

The shaft seal is placed on the MPL-B4530F-SJ74AA servo motor’s shaft near the motor’s front bearing. The shaft seal also protects the servo motor against lubricating oil from a gearbox. However, the shaft seal is not needed when the MPL-B4530F-SJ74AA servo motor is installed and operated in environments that are not prone to fine dust or liquids. Additionally, in such environments, a lower international protection rating is enough for the servo motor. The Allen-Bradley MPL-B4530F-SJ74AA servo motor, like other servo motors in the same family, can be used in a demanding industrial environment since it has a high torque to size ratio. The servo motor operates with a voltage rating of 460 Volts AC and its speed is rated at 3000 revolutions per minute. For feedback, the MPL-B4530F-SJ74AA servo motor contains a single-turn high-resolution encoder. The encoder helps in positioning and controlling the motor.
