The MPL-B320P-SJ72AA is a Bulletin MPL MP‑Series low-inertia rotary servo motor, designed to deliver high dynamic performance with compact size and low rotor inertia. It operates on a 460 V AC (400 V class) supply and uses a 100 mm (3.94 in) square frame (frame size 3) with magnet stack length 20 (50.8 mm / 2.0 in), providing a rated output of 1.5 kW at 5000 RPM. Typical performance data list a continuous stall torque around 3.05–3.5 N·m and peak torque about 6.55–7.9 N·m, making it suitable for applications that demand rapid acceleration, deceleration and accurate positioning.
Feedback is via a single-turn high‑resolution encoder (Sin/Cos 1024 cycles/rev, high effective counts per revolution), which provides precise position and speed information to compatible Kinetix drives. The motor has a keyed shaft extension for easy coupling to gearboxes, pulleys or couplings and uses a SpeedTEC circular DIN power/feedback connector, right‑angle, 180° rotatable, to simplify cabling and allow flexible cable exit orientation in tight panels. The mounting flange follows IEC metric dimensions with free mounting holes (Type FF), ensuring compatibility with standard mechanical interfaces.
The MPL-B320P-SJ72AA is supplied without an integral holding brake and with no shaft seal as standard; the base environmental rating is IP50, which can be increased to IP66 at the shaft when an optional shaft seal and sealed connectors are used. Its low inertia and high torque density make it a strong fit for packaging, printing, material handling, robotics, indexing tables and other high‑speed, high‑precision motion applications when paired with Kinetix 5500/5700/6200/6500 drives.
