MHD112C-035-NG3-AN
MHD Synchronous Motors
MHD112C-035-NG3-AN, Bosch Rexroth Indramat, MHD Synchronous Motors series delivers precision motion control in an industrial-grade servo motor. Designed as a Product Type **Servo Motor**, it combines a compact Motor Size **112** frame with a versatile Motor Length **C** housing. A robust Shaft Design **Plain shaft** and integrated Shaft Seal **Yes** ensure durability in high-speed applications. This motor supports a Power Connection Type **Output Connector** oriented Power Connection Direction **to side A** for streamlined cabinet layout and simplified wiring.
Featuring a liquid-cooled thermal management system, the **Housing Cooling Type** liquid cooling maintains optimal performance under continuous operation. The motor delivers **38.0 Nm** of Continuous Torque at Standstill continuous torque at standstill and withstands dynamic loads with a Holding Brake Torque **70.0 Nm** holding brake. High-resolution positioning is provided by the **Digital servo feedback (HSF)** Encoder Type in a relative detection mode. The precision fit of the Centering diameter **130 mm** taper and the Flange size **192 mm** flange guarantees repeatable mounting, while the Winding Code **035** winding configuration balances torque ripple and thermal efficiency.
Engineers benefit from the MHD112C-035-NG3-AN’s modular integration into Bosch Rexroth Indramat drive platforms, enabling synchronized multi-axis control and simplified parameterization. Its sealed shaft and holding brake deliver exceptional reliability in stop-and-hold scenarios, minimizing drift in safety-critical operations. This versatile servo motor excels in robotics, packaging machinery, and CNC applications where precision, uptime, and compact footprint are paramount.

Frequently Asked Questions
How do the 192 mm flange and 130 mm centering diameter ease mechanical integration of MHD112C-035-NG3-AN?
The standardized flange/pilot pair constrains radial runout and simplifies repeatable mounting with off-the-shelf adapter plates. It shortens alignment time on gantries and transfer stations, while preserving concentricity under dynamic load.
What role does the 70 Nm holding brake play on vertical or safety-critical axes?
The integrated brake clamps the rotor during e-stops or power loss for limiting back-drive on gravity-loaded Z-axes. It reduces drift at rest for protecting tooling and workpieces in machining and pick-and-place cells.
How does power connection to side A benefit cabinet layout when deploying MHD112C-035-NG3-AN in tight machines?
The side-A orientation keeps bend radii compliant and prevents cable loops crossing feedback lines for lowering EMI coupling. It improves service access and reduces wiring time in clustered axes or enclosed frames.
What advantages does the plain shaft with seal provide for MHD112C-035-NG3-AN in washdown-adjacent or coolant-rich environments?
The seal limits ingress of emulsions and fine particulates toward the front bearing set for extending lubrication life. Its plain shaft also simplifies rigid or keyless couplings to minimize micro-slip in high-inertia indexing.
Is the 38.0 Nm continuous torque at standstill on MHD112C-035-NG3-AN suitable for direct-drive tables or heavy conveyors?
Yes, the continuous stall torque at zero speed enables sustained thrust without auxiliary gear reduction when inertia is matched. It’s appropriate for feed axes, wrapping stations or low-ratio reducers demanding consistent low-speed torque.
