The Bosch Rexroth MPN R911279915 (MHD112B-024-NG0-AN) is a synchronous servo motor intended for advanced drive applications. It features a size 112 motor with an aluminum flange (192 mm) and a plain shaft with seal, centering diameter 130 mm, and motor length B. This unit uses liquid cooling and does not include a holding brake. The digital servo feedback (HSF) encoder provides relative position detection. Operating within 0 to +40°C at up to 1000 meters elevation, it supports long-term storage from -20 to +80°C. The MHD112B-024-NG0-AN delivers up to 28.0 Nm continuous torque at standstill (winding code 024) and a maximum velocity of 4500 RPM.

Can the MHD112B-024-NG0-AN operate effectively without a holding brake?

Yes, it’s optimized for dynamic positioning where brake retention isn’t essential. Controlled drive logic and torque management maintain stable shaft control during active operation.

What are the installation considerations regarding the motor’s centering diameter and flange size?

Its standardized 130 mm centering diameter and 192 mm flange size enable direct alignment with compatible Rexroth and third-party mounts. This simplifies setup and ensures precise mechanical coupling.

How does the motor’s winding code 024 affect performance?

The winding configuration determines torque density and voltage characteristics. This balance allows rapid acceleration while maintaining torque consistency across varying loads.

What advantages does a plain shaft with an integrated shaft seal provide?

It prevents contamination ingress into the bearing system while maintaining alignment accuracy. This feature is valuable in environments with fine dust, oil mist, or coolant exposure.

How does liquid cooling impact cabinet design in multi-axis drive systems?

Liquid cooling reduces ambient heat buildup in enclosures, allowing more compact cabinet layouts. It also minimizes the need for forced-air ventilation in tightly packed systems.
