MPL-B320P-SK74AA

The Allen-Bradley MPL-B320P-SK74AA servo motor is a 5000 rpm AC servo motor from the Allen-Bradley MP-series of low-inertia brushless synchronous motors. It has a frame length of 100 millimeters and magnet stack length of 50.8 millimeters. The shipping weight of the motor is approximately 8 pounds. Designed for 400 Volts AC input, the MPL-B320P-SK74AA servo motor delivers 5000 rpm of motor speed, 3.05 N-m of continuous stall torque, and 7.91 N-m of peak stall torque. The rated power output of the motor is 1.5 kilowatts. The rotor inertia is 0.000078 kg-m2. The drive comes with standard control options from the manufacturing facility.

The encoder on the MPL-B320P-SK74AA servo motor is a 1024 sin/cos absolute single-turn encoder. The encoder is compatible with the Hiperface protocol. The motor connects to several supported drive types including the Allen-Bradley Kinetix 300/250, Kinetix 6200/6500, and Kinetix 2000 drives through a circular DIN connector which can be rotated anywhere within 180 degrees. A 24 Volts DC motor brake is part of the MPL-B320P-SK74AA servo motor which has a maximum backlash of 45 minutes, 37 pounds on an inch of holding torque, and a coil current in the range of 0.45 to 0.55 Amps. Because a shaft seal is not provided, the optional shaft seal kit known as the Allen-Bradley MPL-SSN-A3B3 shaft seal kit can be ordered from Allen Bradley. The purpose of the shaft seal is to reduce wear and tear. A shaft key is not included with the servo motor. The mounting flange on the MPL-B320P-SK74AA servo motor is IEC metric. The ratings for radial load force on the motor are as follows: 87 kilograms at 500 rpm, 69 kilograms at 1000 rpm, 55 kilograms at 2000 rpm, 45 kilograms at 3500 rpm, and 40 kilograms at 5000 rpm.
