Allen-Bradley MPL-B330P-HK72AA MP-Series Servo Motor w/ Wittenstein LP

Allen-Bradley MPL-B330P-HK72AA MP-Series Servo Motor w/ Wittenstein LP 090-M01-10

The Allen-Bradley MPL-B330P-HK72AA is a low-inertia, brushless AC servo motor from Rockwell Automation's MP-Series Kinetix line, here paired with a Wittenstein Alpha LP 090-M01-10-111 planetary gear reducer at a 10:1 ratio. The motor is rated for 460V RMS line-to-line, three-phase operation, with a maximum speed of 5000 RPM and a continuous power rating of 1.8/2.4 kW/HP. This combination of servo motor and inline planetary reducer is designed for high-precision, high-dynamic motion control applications where output torque multiplication and reduced reflected inertia are required.

Applications

The Allen-Bradley MP-Series low-inertia servo motors are used in high-performance motion control systems where compact size, rapid acceleration, and precise torque control are required. Paired with a planetary gear reducer, this assembly is well suited for applications such as CNC axis drives, robotic joints, automated assembly equipment, packaging machinery, and other servo-driven axes where torque multiplication and tight positional accuracy are needed. The Kinetix MP-Series is designed to work with Allen-Bradley Kinetix servo drives — including the Kinetix 6000, 6200, 6500, and 2000 families — within a Rockwell Automation Integrated Architecture motion control system. The IP66 shaft seal rating makes the motor suitable for environments where washdown or particulate exposure is a concern. The SpeedTEC DIN connector system supports a single cable family across the full MP-Series motor line, simplifying installation and cable management. This motor dates from late 2013 (date code 1312 per nameplate), placing it in the second generation of the Kinetix MP-Series platform that has been in production since the mid-2000s.
