MHD112C-035-NP3-BN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112C-035-NP3-BN is a high-performance servo motor from the MHD Synchronous Motors series, designed for precise motion control in demanding industrial environments. With a Motor Size of 112 and a Continuous Torque at Standstill of 38.0 Nm, this motor delivers reliable holding force without movement. Utilizing liquid cooling for its housing, it maintains optimal operating temperatures under heavy loads. Its compact Motor Length of C and integrated holding brake enhance its suitability for space-constrained applications requiring quick response.
Featuring a robust holding brake with a rated torque of 70.0 Nm, the MHD112C-035-NP3-BN ensures secure positioning when de-energized. The digital servo feedback encoder (HSF) provides high-resolution feedback and precise speed regulation, while the relative position detection scheme enables accurate incremental positioning. The keyed shaft design, combined with a sealed shaft for protection against contaminants, ensures reliable torque transmission over extended service intervals. Wound with a specialized Winding Code 035, this motor offers optimized current distribution for smooth acceleration and consistent torque output throughout its operating range.
This servo motor is equipped with a centering diameter of 130 mm and a flange size of 192 mm, facilitating straightforward integration into existing machine frames. The output connector power connection, angled toward side B, simplifies cable routing and reduces installation time. Compliance with industrial sealing standards is guaranteed by the built-in shaft seal, enhancing durability in environments exposed to dust or moisture. As a versatile product type in the MHD series, it excels in applications that demand high precision, efficient thermal management, and robust mechanical stability. Choosing the MHD112C-035-NP3-BN means benefiting from superior positional accuracy, reduced downtime, and enhanced productivity in automated manufacturing and process control systems.

Frequently Asked Questions
How does the liquid-cooled housing in MHD112C-035-NP3-BN improve duty capability during cyclic acceleration?
It removes heat directly from the stator jacket by keeping copper and magnet temperatures within design limits under repeated load surges. It sustains torque linearity and reduces thermal derating that would otherwise limit throughput.
What positioning fidelity can its HSF digital servo feedback (relative) deliver for coordinated multi-axis moves?
The high-resolution incremental feedback enables tight velocity loops and low following error with modern Rexroth drives. Its relative encoding also allows electronic homing strategies while maintaining low jitter for contouring tasks.
Why is the 70 Nm holding brake on MHD112C-035-NP3-BN valuable for vertical axes or safety-related stops? (Product code: MHD112C-035-NP3-BN)
The brake supplies static torque independent of drive current for securing loads when de-energized or faulted. It reduces mechanical creep on Z-axes and meets stop-category requirements in many machines.
How does the 38 Nm continuous standstill torque translate to fixture clamping or low-speed pressing? (Product MHD112C-035-NP3-BN)
The motor can deliver rated electromagnetic torque without overheating due to its cooling concept. Itenables precise force control for index locks, low-speed forming and servo pressing cycles.
What integration benefits come from the 130 mm centering diameter and 192 mm flange?
The standardized pilot and flange geometry simplify concentric alignment with gearboxes and machine plates for minimizing runout and bearing loads. Its faster mechanical swap-outs cut mean-time-to-repair in production lines.
