The Allen-Bradley MPL-B420P-RK74AA is an advanced member of the MPL series, featuring a premium permanent magnet design optimized for high-performance applications. Operating at 400 Volts AC, this servo motor supports a frame size of 115 millimeters with a rotor stack length of 50.8 millimeters, achieving a rated speed of 5000 RPM. Its design integrates a resolver feedback system, delivering a continuous stall torque of 4.74 N-m and a peak torque of 13.5 N-m, while maintaining low inertia with a rotor inertia of 0.00026 kg ·m ², ideal for precision control. The motor's robust construction adheres to IEC metric mounting standards and includes a 37 arc minutes maximum backlash holding brake with 10.2 N-m holding torque, further enhanced by a right-angle circular DIN connector that rotates 180 degrees and an IP50 ingress protection rating upgradable to IP66.
