Description
Allen-Bradley MPL-B330P-MJ72AA Servo Motor Wittenstein Alpha SP075S-MF1-5
The Allen-Bradley MPL-B330P-MJ72AA is a compact, low-inertia brushless AC servo motor from Rockwell Automation's MP-Series, here mounted with a Wittenstein Alpha SP075S-MF1-5 inline planetary gearbox. The motor is rated for 460V RMS three-phase operation at up to 5000 RPM and includes a 24 VDC holding brake. The Wittenstein Alpha gearbox is lubricated for life and adds torque multiplication with a precision pinion gear output shaft, making this a ready-to-install servo drive assembly.

Applications
The Allen-Bradley MP-Series low-inertia servo motors are designed for high-performance motion control applications in industrial automation, robotics, CNC machining, packaging machinery, and material handling systems. They are a common choice in Kinetix-based servo systems, where the low rotor inertia allows for fast acceleration and deceleration cycles with precise positioning. The Wittenstein Alpha planetary gearbox increases output torque while reducing output speed, and the pinion gear output shaft is typical of rack-and-pinion linear drive systems used in CNC axes, gantry systems, and custom automation equipment. This combination of an Allen-Bradley brushless servo motor with a German-made Wittenstein Alpha gearbox is a professional-grade, purpose-built assembly suited to demanding motion control environments that require precision, repeatability, and IP66-rated environmental protection.
This Allen-Bradley MPL-B330P-MJ72AA brushless servo motor with Wittenstein Alpha SP075S-MF1-5 gearbox has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in use. The motor body and gearbox housing are intact; the blue gearbox casing and mounting flange show normal service wear, and the pinion gear output shows some surface patina and wear on the teeth consistent with prior use. The multi-pin circular connectors at the rear appear undamaged. Please note that we may have multiple units in stock and the unit you receive may vary slightly from the one photographed, but will be functionally equivalent. Please view our photo set and contact us if you have any questions.
