The Allen-Bradley MPL-B320P-SK74AA is a high-performance 5000 rpm AC servo motor from the company's MP-series of low-inertia brushless synchronous motors. It features a frame length of 100 millimeters and a magnet stack length of 50.8 millimeters, with a shipping weight of around 8 pounds. This motor operates on a 400 Volt AC input and offers a motor speed of 5000 rpm, delivering continuous stall torque of 3.05 N-m and peak stall torque of 7.91 N-m. It has a rated power output of 1.5 kilowatts and a rotor inertia of 0.000078 kg-m².
The motor includes standard control options and is equipped with a 1024 sin/cos absolute single-turn encoder, compatible with the Hiperface protocol. It connects to various supported drives, such as the Allen-Bradley Kinetix 300/250, Kinetix 6200/6500, and Kinetix 2000 drives, via a circular DIN connector that rotates up to 180 degrees. The motor also features a 24 Volts DC brake with a maximum backlash of 45 minutes, holding torque of 37 pounds on an inch, and coil current ranging between 0.45 to 0.55 Amps.
A shaft seal is not included, but an optional shaft seal kit (Allen-Bradley MPL-SSN-A3B3) can be purchased to reduce wear and tear. No shaft key is included, and the mounting flange meets IEC metric standards. The radial load force ratings are 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.
