The R911280217 (MHD115B-024-NG0-BN) is a MHD synchronous servo motor from Bosch Rexroth engineered for integration in automation systems, machine tools, and similar applications. It features liquid cooling, a digital servo feedback (HSF) encoder with relative position detection, and a plain shaft design with sealing rings. The device provides 50.0 Nm continuous torque at standstill and operates at speeds up to 4,000 rpm. Specifications include a motor length B, centering diameter of 180 mm, flange size of 192 mm, and motor size 115. The shaft is plain and sealed, with the power connection directed to side B via an output connector. The enclosure is rated IP 65, suitable for operation at ambient temperatures up to 40°C, 95% humidity, and 1,000 m altitude.

Frequently Asked Questions

How does liquid cooling improve the servo motor’s performance?

The liquid cooling removes excess heat allowing sustained high torque without thermal overload. The thermal stability enhances precision and prevents performance drift during long duty cycles.

What benefit does a plain shaft with seal provide in industrial use?

The plain shaft ensures precise coupling alignment with low vibration levels. The seal prevents contamination entry and protects the bearing system in dusty or wet conditions.

Why is digital servo feedback critical in precision automation?

The digital servo feedback delivers real time position and speed data to the controller. The accuracy of this feedback minimizes positioning errors and enables synchronized multi axis control.

How does continuous torque at standstill affect motion control systems?

The ability to maintain rated torque at zero speed enables stable holding of loads. The feature is essential for robotics presses and tension control systems requiring precise load retention.

How should the output connector on side B be oriented during wiring?

The connector should be oriented to minimize cable strain and maintain bending radius limits. The layout must ensure electromagnetic compatibility with nearby signal lines.
