The Bosch Rexroth MPN R911293796 (MHD112C-035-NG3-BN) is a synchronous servo motor featuring a 192 mm flange, 130 mm centering diameter, and four 14 mm mounting holes. It utilizes a plain shaft with a sealing ring and a side B power connector. This model is equipped with integrated digital servo feedback (HSF) for relative position detection and supports both natural convection and liquid (surface) cooling. It delivers 38.0 Nm continuous torque at standstill and reaches a rated speed of 2500 RPM with a maximum speed of 4000 RPM. The holding brake provides 70 Nm of torque at 24 V, with a 1.29 A rated current, 53 ms connection, and 97 ms disconnection time. Optimal operating conditions are 0–40°C ambient temperature and up to 1000 m altitude.

Frequently Asked Questions

Why is a 70.0 Nm holding brake valuable on MHD112C-035-NG3-BN vertical or safety-critical axes?

The brake resists back-driving and locks the load during power loss to enable safe stops and tool changes without creep. It reduces reliance on clamps in vertical Z-axes and gantry hoists.

What does liquid cooling change in the MHD112C-035-NG3-BN’s thermal behavior compared with convection-cooled variants?

The coolant removes stator heat efficiently for sustaining torque and reducing thermal derating during extended duty cycles. It enables denser machine layouts, shorter cycles and steadier servo bandwidth under aggressive acceleration profiles.

How does the HSF digital servo feedback in the MHD112C-035-NG3-BN improve position control during coordinated multi-axis moves?

The integrated HSF feedback delivers high-resolution, low-latency relative position data for allowing tighter gains and reduced following error. Its interpolation and electronic gearing improve across CNC, robotics and packaging axes.

What does 38.0 Nm continuous torque at standstill imply for servo sizing and tuning on MHD112C-035-NG3-BN axes?

It indicates the motor can supply substantial static torque without overheating for enabling tight holds and high preload forces. Its engineers can select higher gains while maintaining thermal headroom at low speed.

How does the side-B power connection orientation and output connector style affect cabinet layout and serviceability?

The side-B routing keeps motor leads clear of moving cable carriers in many mounting orientations for reducing flex stress. Its detachable output connectors allow rapid swap-outs and maintain consistent shielding practices during maintenance.
