The Bosch Rexroth Indramat MHD112C-058-PP3-AN from the MHD Synchronous Motors series is a high-performance servo motor designed for demanding industrial applications. This Motor Size 112 unit features a compact Motor Length C frame and a robust Winding Code 058 to ensure consistent torque delivery. Equipped with liquid cooling via its Housing Cooling Type, the motor maintains optimal operating temperatures even under heavy loads. A digital servo feedback w/ integrated encoder and absolute (>4096 revolutions) position detection provide precision control and reliable motion feedback.

Engineered for continuous operation, the MHD112C delivers a Continuous Torque at Standstill 38.0 Nm while the integrated holding brake offers a Holding Brake Torque 70.0 Nm for secure load retention when power is removed. The Centering diameter 130 mm and Flange size 192 mm ensure precise alignment and simple mounting in compact assemblies. Its Keyed Shaft design and Shaft Seal Yes construction protect against contamination and simplify mechanical coupling. Each motor is preconfigured with a side-entry Power Connection Direction to side A and an industrial-grade Output Connector for streamlined wiring and rapid integration.

Built for seamless system integration, this MHD series motor supports high-duty cycles and rapid response times in dynamic automation environments. The combination of liquid cooling and high-resolution encoder feedback yields thermal stability and motion accuracy that optimize machine throughput and reduce downtime. With its robust shaft sealing and integrated holding brake, the MHD112C-058-PP3-AN delivers longevity and reliability, making it an ideal choice for precision-driven applications in packaging, robotics, and CNC machinery.

Frequently Asked Questions

What role does the 70 Nm holding brake play on the MHD112C-058-PP3-AN during power-off or fault conditions?

The brake clamps the rotor with 70 Nm to secure vertical or overhauling loads when torque current is absent. It enables controlled stops, protects mechanics during faults and simplifies safety compliance for suspended tooling.

How does the liquid-cooled housing of the MHD112C-058-PP3-AN affect thermal behavior during high-duty cycles?

The liquid circulation in the stator jacket extracts losses for keeping windings within limits during sustained duty. It stabilizes torque and reduces thermal derating that is suitable for enclosed cabinets and dense multi-axis packaging or printing machines.

Why is the digital servo feedback with integrated absolute (>4096 rev) encoder advantageous on MHD112C-058-PP3-AN?

The integrated multi-turn absolute encoder (>4096 revolutions) preserves axis position after a power cycle for avoiding homing sequences and downtime. Its digital commutation yields precise phase alignment and smoother torque at crawl speeds for accurate indexing and registration.

How do the 130 mm centering diameter and 192 mm flange influence alignment and structural stiffness?

The 130 mm pilot establishes concentricity with the machine face for preventing radial misalignment and coupling fretting. Its 192 mm square flange increases joint rigidity to improve dynamic positioning fidelity during reversals and reducing bearing loads from misaligned fastening surfaces.

What reliability benefits come from the keyed, sealed shaft on the MHD112C-058-PP3-AN?

It transfers torque without relying solely on frictional clamping for preventing hub slippage during emergency deceleration. Its contact seal limits coolant or dust ingress for preserving bearing grease and maintaining encoder signal quality on MHD112C-058-PP3-AN across extended duty cycles.
