MHD112B-035-NG1-BN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112B-035-NG1-BN motor is part of the MHD Synchronous Motors series and represents a high-performance Servo Motor designed for precision motion control applications. This model features a holding brake with a holding torque of 22.0 Nm and employs liquid cooling via its housing to maintain optimal operating temperatures under heavy loads. With a Motor Size of 112 and a Flange size of 192 mm, it is ideally suited for demanding industrial automation systems that require reliable start-stop positioning and continuous torque delivery.
In detailed technical terms, the MHD112B-035-NG1-BN is equipped with a Digital servo feedback (HSF) Encoder Type and uses a Relative method for position detection, ensuring precise feedback for closed-loop control. Its Continuous Torque at Standstill is 28.0 Nm, while the Winding Code of 035 corresponds to an inductivity of 5.5 mH and a resistivity of 0.43 Ω, optimizing electromagnetic performance. The motor’s Centering diameter of 130 mm and Motor Length of B dimension provide consistent mechanical integration, and the Shaft Design features a Plain shaft with an integrated Shaft Seal to guard against contamination.
Additional design considerations include a Power Connection Direction to side B via an Output Connector, simplifying installation and cable routing in confined machine cabinets. The use of liquid cooling enhances overall efficiency by dissipating heat more effectively than air-cooled alternatives, while the robust shaft seal and precision flange ensure durability and resistance to environmental stress. As a fully shielded industrial servo motor, the MHD112B-035-NG1-BN meets stringent performance requirements and delivers reliable torque, speed, and positional accuracy, making it an excellent choice for high-duty cycle, continuous-operation applications in manufacturing and process automation.

Frequently Asked Questions
How does the MHD112B-035-NG1-BN manage heat during continuous operation?
It uses a liquid-cooled housing that circulates coolant around the stator, maintaining stable temperatures and preventing thermal overload during extended duty cycles. This allows sustained torque output under heavy mechanical loads.
How should the power connector orientation be considered during installation?
Its side-B output connector design simplifies cable routing in tight machine enclosures. Installers can minimize strain and interference by aligning connectors with existing power distribution paths.
How does the encoder type in the MHD112B-035-NG1-BN affect positioning accuracy?
The digital servo feedback encoder provides precise, real-time position data for closed-loop control. This minimizes deviation and ensures consistent alignment during dynamic motion sequences.
What impact does the inductivity value have on motor performance?
A moderate inductivity of the windings helps balance torque smoothness and response speed. It reduces electrical noise while maintaining stable control under variable loads.
How does the motor’s plain shaft design influence coupling options?
The plain shaft allows flexible coupling with various drive components without mechanical keyways. This simplifies alignment but requires secure clamping to prevent slippage.
