MPL-B330P-MJ72AA | Allen-Bradley Brushless Servo Motor, 400V, 1.8 kW, 5000 RPM

The MPL-B330P-MJ72AA is a servo motor from Allen-Bradley's MP-Series Low Inertia line, designed for high-performance motion control applications. It operates on a 400V AC voltage class and features a 100 mm frame with a 76.2 mm magnetic stack. This model has a continuous torque of 4.18 Nm and a rated power output of 1.8 kW, ideal for precise and dynamic motion profiles. It comes with a right-angle, 180° rotatable circular SpeedTec DIN connector and does not include a shaft seal by default. The motor is equipped with a 1024 sin/cos multi-turn absolute encoder using the Hiperface protocol for accurate position feedback.

No, the MPL-B330P-MJ72AA does not come with a shaft seal as standard. However, it is compatible with the optional Allen-Bradley shaft seal kit (catalog MPL-SSN-A4B4), which can be added to improve environmental resistance. Installing a shaft seal enhances the motor's protection rating from IP55 to IP65, making it suitable for dusty or moist environments. The seal should be serviced every 3–12 months depending on application demands, as it is subject to wear. This ensures longevity and sustained performance in harsh conditions.

The recommended ambient operating temperature range for the MPL-B330P-MJ72AA is 0°C to 40°C (32°F to 104°F). Operation outside this range may result in overheating or degraded performance. For optimal cooling, users should ensure adequate airflow and consider the motor’s mounting orientation. If a shaft seal is installed, verify that environmental temperatures do not exceed sealing material limits. Continuous monitoring and proper ventilation help maintain operational reliability in industrial environments.

The Allen-Bradley MPL-B330P-MJ72AA delivers a continuous torque of 4.18 Nm and a rated power of 1.8 kW. These specifications make it suitable for medium-load applications with high-speed and precise positioning requirements. It maintains reliable torque output across a wide operating range, thanks to its low-inertia rotor design. The combination of power and efficiency makes it a popular choice for packaging, converting, and automated material handling systems. Additionally, it supports seamless acceleration and deceleration cycles in dynamic environments.

Yes, the MPL-B330P-MJ72AA servo motor is currently still in production and supported by Rockwell Automation. It is a part of the active MP-Series Low Inertia product family, which is widely used in industrial applications. The model is compatible with modern Kinetix drives, ensuring continued relevance and integration in automation systems. Users can expect long-term support, replacement parts, and firmware updates for this product. However, for mission-critical systems, it's always advised to verify lifecycle status through Rockwell’s Product Lifecycle Status tool.
