MHD112C-058-NG0-RN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112C-058-NG0-RN servo motor is a robust member of the MHD Synchronous Motors series designed for high-performance motion control in industrial automation. With a continuous torque at standstill of 38.0 Nm and a motor size of 112, this motor delivers strong holding and dynamic torque for precision positioning tasks. Engineered without a holding brake, this servo motor enables seamless integration into automated systems where controlled stopping is managed externally. Its liquid cooling housing ensures efficient heat dissipation, making it ideal for continuous operation under demanding load cycles.
This motor features a digital servo feedback (HSF) encoder paired with relative position detection, providing accurate feedback for closed-loop control. The plain shaft design and integrated shaft seal protect internal components against contaminants, extending the service life even in harsh environments. The centering diameter of 130 mm and flange size of 192 mm facilitate straightforward mechanical coupling, reducing installation time. Power connections are made via a right-oriented power connector, streamlining cable routing in compact machine designs. The winding code 058 identifies the specific coil configuration optimized for responsive torque delivery and minimal heat generation.
Built for compatibility and durability, the MHD112C-058-NG0-RN supports liquid cooling to maintain optimal operating temperatures during high-duty cycles, enhancing efficiency and reducing thermal stress. The absence of an integrated brake allows for flexibility in system design and simplifies maintenance procedures. Standard servo drive interfaces ensure seamless communication with modern controllers, while the robust shaft seal safeguards against moisture and debris ingress. In industrial applications, this motor's precise torque control, reliable feedback, and efficient thermal management translate into reduced downtime, improved throughput, and extended equipment lifespan.

Frequently Asked Questions
How do the 192 mm flange and 130 mm centering diameter aid mechanical integration of MHD112C-058-NG0-RN?
These standard interfaces simplify alignment to gearboxes and direct-drive couplings for minimizing runout and assembly time. Its geometry supports repeatable concentricity and load distribution, particularly in rigid machine frames.
What role does the shaft seal and plain-shaft configuration play in lifecycle and coupling options for MHD112C-058-NG0-RN?
The radial shaft sealing ring protects interior bearings and rotor from contaminants for extending service in dusty or mist-laden environments. Its plain shaft offers broad compatibility with clamp hubs, bellows couplings and precision gear inputs.
Does MHD112C-058-NG0-RN support harsh-duty environments from a protection and insulation standpoint?
The IP65 protection with Class F insulation on comparable MHD112C variants indicates dust-tight construction and elevated thermal class. It supports deployment near coolant spray zones with appropriate sealing practices.
For multi-axis CNC or converting lines, what positioning benefits arise from MHD112C-058-NG0-RN’s 38 Nm standstill torque and liquid cooling?
The high continuous torque at zero speed provides stiff holding under cutter load or web tension without additional brakes. Its liquid cooling preserves servo bandwidth during long dwell periods for maintaining contour accuracy across shifts.
What advantages does the HSF digital servo feedback with relative position detection provide in this motor?
The HSF encoder yields fine quantization and low jitter for velocity loops to enable accurate speed/position regulation. Its relative detection simplifies commissioning with drives supporting electronic homing and ensures resilient operation when absolute referencing isn’t required.
