The Bosch Rexroth servo motor MPN R911281302 (MHD115B-024-NG1-AN) is designed for automation tasks requiring high power and precision. This model features a plain shaft with shaft seal, centering diameter of 180 mm, flange size of 192 mm, and motor size 115 with length code B. It utilizes rare earth permanent magnets for electronic commutation and increased cyclic overload capacity. The motor integrates a 70.0 Nm electrically-activated holding brake and employs digital servo feedback (HSF) for relative position detection. It operates with a continuous torque at standstill of 50.0 Nm, supports liquid cooling for thermal management, and is suitable for environments up to 40°C, 95% relative humidity, and 1000 m installation altitude. Power connection is via output connector to side A.

How does a relative position detection system affect calibration requirements?

The relative detection method requires a homing procedure at startup to establish a reference. The design reduces sensor complexity but needs controlled initialization for accuracy.

What installation considerations arise from the 180 mm centering diameter and 192 mm flange size?

The larger flange and centering interface demand rigid mounting surfaces for alignment stability. The setup minimizes vibration and misalignment during high-speed operation.

How does continuous torque at standstill influence machine productivity?

The motor’s ability to maintain torque without movement supports steady load holding during precision processes. The feature enables reliable performance in positioning or tension control systems.

Why is a plain shaft design advantageous for mechanical coupling?

The plain shaft simplifies integration with couplings or pulleys without complex fittings. The structure reduces mechanical play and supports smooth torque transmission.

What benefit does a shaft seal provide in demanding environments?

The seal prevents ingress of dust and fluids that could damage internal bearings. The protection extends service life and ensures consistent torque output in industrial conditions.
