The Bosch Rexroth Indramat MHD112D-024-NG0-BN from the MHD Synchronous Motors series is a high-precision servo motor designed for demanding industrial applications. With a motor size of 112 and a compact motor length "D" dimension, this unit delivers a robust footprint optimized for integrated drives. Mechanical alignment is simplified by the 130 mm centering diameter and a standard 192 mm flange size, ensuring seamless interchangeability. Built for professional automation environments, the MHD112D combines structural rigidity with advanced feedback functions.

Featuring a closed-loop digital servo feedback (HSF) encoder, the motor guarantees accurate position tracking with relative position detection capability. It operates without a holding brake, relying on precise control to maintain standstill stability under load. Continuous torque at standstill reaches 48.0 Nm, providing substantial holding power when dynamic motion ceases. Thermal management is assured by an efficient liquid cooling house, extending duty cycles and minimizing overheating risks.

Installation and connectivity are streamlined with a side B power connection direction and a robust output connector interface that meets IP standards. A durable plain shaft with integrated shaft seal protects against ingress and ensures longevity in harsh environments. The specialized winding code 024 optimizes the motor’s electrical characteristics for high responsiveness and minimal torque ripple. Compatible with a wide range of Bosch Rexroth drive controllers, the MHD112D-024-NG0-BN offers straightforward commissioning and reliable performance under continuous industrial operation.

Frequently Asked Questions

What does the HSF digital servo feedback in the MHD112D-024-NG0-BN actually do in closed-loop motion control?

It provides serial, noise-resilient position and velocity data directly to the drive to enable tight loop gains and smooth interpolation. It supports relative position tracking and seamless pairing with Rexroth drives.

What integration advantages come from the 192-mm square flange and 130-mm centering diameter on MHD112D-024-NG0-BN during retrofit or swap-out?

The standardized 192-mm square flange with 130-mm pilot ensures concentricity and repeatable alignment for minimizing shimming during retrofit. It speeds mechanical interchangeability across MHD112 variants and simplifies jigging for precision axes during planned downtime.

How is the 48.0 Nm continuous torque at standstill typically applied in industry scenarios for axes driven by the MHD112D-024-NG0-BN?

The 48.0 Nm continuous standstill torque suits clamping axes on machining centers, web-tension stands in printing and infeed stations on packaging lines. It enables steady force at zero speed for precise setup, threading, or dosing operations.

Can MHD112D-024-NG0-BN be commissioned with IndraDrive controllers, and which feedback interface is used during setup?

Yes, the MHD112D-024-NG0-BN uses Rexroth’s HSF digital feedback interface recognized by IndraDrive control sections for enabling automatic motor parameter identification and encoder handshake for quick commissioning and safe-torque-off integration.

How does the side-B power connection orientation on MHD112D-024-NG0-BN affect cable management in cabinets or gantry designs?

The side-B power connection routes high-current leads away from feedback cabling and moving elements for improving EMC and service access. It also supports alternate connector orientations for easing cabinet routing and gantry clearance limitations.
