The MPL-B310P-MJ74AA servo motor is an MP series low-inertia servo motor manufactured by Rockwell Automation. This motor's specifications are 5000 revolutions per minute, 400 Volts AC, 7.7 kilowatts, 0.000044 kilograms per meter (square) rotor inertia, 1.58 Newton-meter of continuous stall torque, 3.61 Newton-meter of peak stall torque, 2.4 Amperes of continuous stall current, 7.1 Amperes of peak stall current, a 115-millimeter frame, and an IEC metric mounting flange. The MPL-B310P-MJ74AA servo motor is equipped with a 24 Volts DC holding brake that is suitable for maintaining the same position at zero (0) revolutions per minute and it features a multi-turn high-resolution encoder. The speed and torque capabilities of the MPL-B310P-MJ74AA low-inertia servo motor are designed to meet the requirements of different motion systems and applications like packaging, electronics assembly, and automotive applications. The length of its magnetic stack is 1 inch, and its high-energy rare-earth magnets provide improved acceleration across applications.

The MPL-B310P-MJ74AA servo motor can achieve an IP66 environmental protection rating when a Rockwell Automation MPL-SSN-A3B3 seal kit is affixed to the base of its shaft and when environmentally protected cable connectors are connected to its circular DIN rotatable connectors. Additionally, its coil design improves its torque capabilities without increasing motor size. The MPL-B310P-MJ74AA servo motor features a smart motor technology that automatically reports the ID on the servo motor’s memory to controllers in the motion system to reduce commissioning time. Note that the MPL-B310P-MJ74AA servo motor is only 1 component of a complete servo motion system that usually consists of other devices including amplifiers, Rockwell Automation Kinetix drives, encoders, and braking mechanisms. Standard factory designated control options are available on this servo motor.
