The MPL-A310F-MK72AA servo motor is a low-inertia brushless servo motor from Allen-Bradley/Rockwell Automation. This servo motor is a member of the Bulletin MPL product line. The Bulletin MPL series servo motors have a high torque-to-size ratio, allowing for a smaller motor size while also delivering more torque. This AC rotary servo motor has a voltage rating of 230 Volts AC. This MPL servo motor's main features include Smart Motor Technology, lower rotor inertia, and the hiperface encoder protocol. Low-inertia motors in the MPL series have innovative winding technology that generates up to 40% more torque per unit size than conventional motors. The MPL-A310F-MK72AA servo motor is available in frame size 3, which is equal to 100 millimeters, as defined by the IEC 72-1 standards. The magnetic stack length of the motor is 1 inch or 25.4 millimeters.

The MPL-A310F-MK72AA MPL series servo motor has a maximum rated rotor speed of 3000 RPM. It provides a continuous stall torque of 1.58 N-m and a peak torque of 3.61 N-m. The rated output power of this motor is 0.46 kilowatts. It features an absolute multi-turn high-resolution encoder for feedback. The MPL-A310F-MK72AA servo motor has a keyless shaft extension with an optional shaft seal, but no brake option. The use of a shaft seal on the motor's shaft is recommended because it raises the shaft's housing protection rating from IP 50 to IP 66. This motor comes with 180 degrees rotatable circular DIN, right-angle connectors. This motor's SpeedTEC DIN connectors provide it with greater mounting flexibility. Enough clearance must be provided around the motor for proper airflow when mounting it in order for the motor to maintain its proper operating temperature range of 32 to 104 degrees Fahrenheit.
