MPL-B330P-SJ74AA

The MPL-B330P-SJ74AA is an Allen-Bradley servo motor. It is part of the Kinetix motion control system, specifically, the MPL series of low inertia motors. Utilizing high-energy rare earth magnets, this motor boasts of faster acceleration and high torque to size ratio. Additionally, this motor supports modern digital communication technology as it is capable of Smart Motor Technology and Hiperface (Stegmann) encoder and drive communication protocol. The MPL-B330P-SJ74AA is drive by a single servo drive. Being part of the Kinetix system, it may be coupled to a variety of servo drives which are Kinetix 5500, Kinetix 5700, Kinetix 6200/6500, Kinetix 6000, Kinetix 300/350, Kinetix 2000, and Kinetix 7000. For feedback of the motor’s rotation in relation to the current position, the MPL-B330P-SJ74AA is provided with a 1024 sin/cos single turn high resolution absolute encoder. This encoder supports Hiperface (Stegmann) protocol, eliminating traditional communication between the drive and the motor instead, exchanges data via high-speed digital communication. Additionally, with the Smart Motor Technology, this motor can be identified over the network as it is able to retain this information via the motor’s on-board memory. The MPL-B330P-SJ74AA operates at maximum speed of 5000 rpm. It delivers output power of 1.8 kW, continuous stall current of 6.1 Amperes and peal stall current of 19.0 Amperes. It has rotor inertia of 0.00012 kg-m2 (0.0010 lb-in.-s2). It comes with an integral holding brake that maintain the motor shaft to 0 rpm. The MPL-B330P-SJ74AA comes in a small package, requiring minimum installation space. It delivers high levels of Torque compared to its size with ratings of 4.18 N-m continuous stall torque and 11.1 N-m peak stall torque.

The MPL-B330P-SJ74AA servo motor is part of the premium permanent-magnet servo motor series manufactured by Allen-Bradley. It belongs to the low-inertia servo motor type and its ratings are 400 Volts AC of power, 0.00012 kg-m2 of rotor inertia, 5000 revolutions per minute, 4.18 N-m of continuous stall torque, and 6.1 Amps of the continuous stall current. This brushless servo motor is equipped with a single-turn high-resolution encoder for speed feedback and it also has a 24 Volts DC holding brake that is suitable for holding the motor shafts at 0 RPM and at up to the rated brake holding torque level. It comes with a shaft key for fastening the motor shaft to machines. When applied within the correct ratings, the MPL-B330P-SJ74AA servo motor can remain operational for extended periods without overheating or experiencing a reduction in performance. Its recommended operating temperature range is from 0 to 40 degrees Celsius and its high-quality winding insulation provides adequate heat transfer in all conditions. The right-angle SpeedTEC circular DIN cable connector of the MPL-B330P-SJ74AA servo motor allows for the flexible orientation of connectors. The connectors can be rotated 180 degrees and they are compatible with different power, brake, and feedback cables that are recommended for MP-series servo motors. The MPL-B330P-SJ74AA low-inertia servo motor does not have a shaft seal kit, but installing an Allen-Bradley MPL-SSN-A3B3 shaft seal that must be replaced every 3 months makes it suitable for applications that require an IP 66 protection rating at the shaft. Note that the holding brakes on this motor can be occasionally used as a stopping brake but this can reduce the brake’s lifespan.
