MPL-A520K-SJ22AA

The MPL-A520K-SJ22AA servo motor is a CE marked and UL listed servo motor manufactured by Allen-Bradley/Rockwell Automation. The power requirement for this servo motor is the standard 230 Volts AC (200 Volts class) rating. This is a brushless type of servo motor built with rare earth magnets that belongs to the Allen-Bradley MP series of low-inertia servo motors. The MPL-A520K-SJ22AA servo motor has a closed loop feedback device (encoder) that reacts to disturbances in the motion system. This shaft-mounted encoder is a single-turn high-resolution type of encoder that sends information to the servo drive for adjusting the control signal for the accurate movement of the servo motor. This smart motor technology is combined with a high torque-to-size ratio to make it popular with industrial machine users.  Furthermore, MP series servo motors have an onboard memory to save the motor identity and to be automatically recognized by Allen-Bradley industrial automation devices like servo drives and PLC controllers.

The Allen-Bradley MPL-A520K-SJ22AA servo motor contains a shaft key but it does not have a shaft seal. This results in an IP 50 protection rating. The shaft’s maximum speed is 4000 rpm. This MP series low-inertia servo motor uses an innovative winding encapsulation to reduce the size of the motor. It is also constructed with high-energy magnets to deliver the quickest possible acceleration of the motor. The MPL-A520K-SJ22AA servo motor’s housing is made of aluminum, which provides excellent heat transfer. The continuous stall torque for this motor is rated at 95 pounds on an inch. It provides excellent torque values even at zero speed. The output power rating of the unit is 3.5 kilowatts.
