Frequently Asked Questions
Why is the keyed shaft with shaft seal significant for MHD112C-035-NP0-AN coupling reliability?
The DIN 6885-1 key transmits torque without slip for easing hub alignment and resisting micro-motion under reversing loads. Its seal protects bearings from contaminants. Together they improve coupling longevity in wet or dusty cells.
How do the rated speed (≈2500 rpm) and voltage range influence drive sizing for MHD112C-035-NP0-AN?
The rated frequency around 167 Hz and voltage typically 303–325 V (model/config dependent). It is important to choose a drive that matches back-EMF, current and speed headroom for the chosen cooling mode. This ensures field-weakening and regeneration are controlled.
What are the mechanical interface details—192 mm flange and 130 mm centering diameter—and how do they affect mounting?
The 192 mm square flange with 130 mm pilot simplifies coaxial alignment to gearheads or machine plates for minimizing runout-induced vibration. Its proper pilot fit and bolt preload preserves servo stiffness and dynamic accuracy (per your spec).
How does the side-A power output connector orientation on MHD112C-035-NP0-AN aid cabinet and cable routing?
The A-side exit keeps power cables clear of feedback and coolant lines for reducing cross-talk and easing strain-relief in tight frames. It also supports IP-rated connections appropriate for industrial environments.
Which Rexroth drive families interoperate with MHD112C-035-NP0-AN, and what applications benefit?
The MHD motors are commonly paired with Rexroth ECODRIVE families using SERCOS/analog interfaces for targeting machine tools, packaging and handling systems. Its correct firmware variants optimize contouring, synchronization and multi-axis coordination.

Internal Product Review
The Rexroth Indramat’s MHD112C-035-NP0-AN servo motor is designed with a 192 mm flange and a side A output connector for flexible connectivity. It relies on liquid cooling mechanism for maintaining favorable thermal range and for feedback back it relies on HSF digital encoder to provide relative position detection. This unit specifies 38.0 Nm at standstill, keyed shaft with seal and 2500 rpm nominal speed to suit industrial systems.
