MPL-B420P-MJ74AA

The Allen-Bradley MPL-B420P-MJ74AA is an MP-Series low-inertia, standard brushless AC synchronous rotary servo motor manufactured by Rockwell Automation. It has a rated speed of 5000 RPM, a voltage class of 400V, and an armature voltage of 460V. The magnet stack length of this motor is 2 inches and its frame size is 115 mm, with the magnets used on the MPL-B420P-MJ74AA motor of a high-energy rare-earth type. This motor also features a multi-turn, 1024 sin/cos, absolute encoder feedback and a 24V DC brake. Note that the electromechanical design of the encoder does not require a battery. Standard factory options are available with the MPL-B420P-MJ74AA motor and its connectors are circular SpeedTec DIN connectors that are 180o rotatable and with a right angle. It uses an IEC metric, Type FF free mounting holes mounting flange and has a keyed shaft extension enclosure. The continuous stall torque of the MPL-B420P-MJ74AA motor is 4.74 Nm or 42 lb-in and its peak stall torque is 13.5 Nm or 120 lb-in. It also has a motor rated output of 1.9 kW and a speed at a motor rated output of 5000 RPM. MP-Series motors, such as the MPL-B420P-MJ74AA motor, feature a low rotor inertia, Smart Motor Technology, and a high torque-to-size ratio. They primarily deliver a significantly higher torque while featuring a reduced motor size, as required especially by high-performance motion systems. These motors are ideal for applications like metal forming, packaging, material handling, automotive, converting, and electronic assembly.

The Allen-Bradley MPL-B420P-MJ74AA is an Brushless AC synchronous servo motor that is part of the low-inertia, high torque to size ratio output servo motors. The MPL-B420P-MJ74AA being a servo motor, requires use of a servo drive to fully utilize its position and motion control capability. This servo motor is especially compatible with the Kinetix Servo drive family, specifically, Kinetix 5500, Kinetix 5700, Kinetix 6200/6500, Kinetix 6000, Kinetix 300/350, Kinetix 2000, and Kinetix 7000.

Interpreting the catalog number, the MPL-B420P-MJ74AA depicts that this servo motor has a 460 Volt AC rated armature, belonging to the 400 Volt class. It has a 115 millimeter frame size with 2-inch Magnetic Stack Length with output speed that can reach up to 5000 RPM. Acting as position feedback device, it comes with a built-in 1024 sin/cos, absolute multi-turn encoder that supports Hiperface protocol which is a digital communication protocol between the servo motor and the servo drive. It also comes with an integral 24 Volt DC holding brake, a keyed shaft and designed for use with Circular SpeedTec DIN connector, right angle, 180° rotatable.

The MPL-B420P-MJ74AA is ideally used in a wide variety of industrial applications. Some of these applications are Packaging, Converting, Material Handling, Electronic Assembly and Automotive applications. It has an IP50 Protection rating even without a shaft seal installed. It may attain up to IP65 if installed with the appropriate shaft seal along environmentally sealed cable connectors. Additionally, this servo motor also supports the Smart Motor Technology wherein motor identity can be recognized over the communication network. This contributes to faster and lowered risk when configuring more than 1 motors in the network.
