MPL-B420P-RJ22AA

The Allen-Bradley MPL-B420P-RJ22AA servo motor is a 5000 rpm AC servo motor. It belongs to the MP series of compact synchronous motors which are available in 9 frame sizes, with a continuous stall torque ranging from 0.26 to 163 N-m and a peak stall torque ranging from 0.77 to 278 N-m. The MP series of low-inertia motors come with single-turn/multi-turn encoders or resolvers. The rated motor speed for the MPL-B420P-RJ22AA servo motor is 5000 rpm and the rated output power is 1.9 kilowatts. The rotor inertia is 0.00025 kg-m2. The continuous stall current and the peak stall current are 6.4 Amps and 22.0 Amps, respectively. The continuous and peak stall torque ratings are 4.74 N-m and 13.5 N-m, respectively. The input voltage for the MPL-B420P-RJ22AA servo motor is 400 Volts AC.

The weight of the MPL-B420P-RJ22AA servo motor is 9.4 pounds. The motor frame size is 115 millimeters and the magnet stack length is 50.8 millimeters. The feedback comes from an integrated resolver. The compatible drives such as the Allen-Bradley Kinetix 7000, Ultra 3000, and Kinetix 6000 drives connect to the servo motor through a shaft-facing circular bayonet connector. The MPL-B420P-RJ22AA servo motor comes with a shaft key but without a shaft seal or brake. Both the shaft seal and brake are available as options and they can be ordered from Allen-Bradley if required. The catalog number of the optional shaft seal kit is MPL-SSN-A4-B4. The addition of an optional shaft seal helps to reduce wear and improves the IP rating of the motor from IP 50 to IP 66. The weight of optional motor brake is 13.2 pounds, its holding torque is 90 pounds on an inch and its peak backlash is 37 arc minutes. The MPL-B420P-RJ22AA servo motor comes with standard options.
