The R911278514 (MHD112B-058-NG1-BN) is a Bosch Rexroth synchronous servo motor incorporating a plain shaft with a radial shaft sealing ring and a high-capacity bearing suitable for high radial loads. The motor’s flange meets DIN 42948 standards, supporting straightforward integration within machine assemblies. Key specifications include a winding inductivity of 2.2 mH, B length, a power connector on side B, and a rotor moment of inertia of 110 x10-4 kgm². The shaft end complies with DIN 748 Part 3, and the device operates at a rated speed of 3000 min⁻¹ under natural cooling at 60K. The holding brake delivers 22.0 Nm torque, with continuous standstill torque rated at 28.0 Nm. Liquid cooling is implemented. The unit features a digital servo (HSF) encoder for relative position detection, a centering diameter of 130 mm, and a flange size of 192 mm.

Frequently Asked Questions

What encoder functionality supports motion control with this model?

It uses a digital HSF encoder with relative feedback. Homing is required after power loss to re-establish position reference in closed-loop systems.

How does the MHD112B-058-NG1-BN ensure torque output during static hold operations?

It delivers 28.0 Nm of continuous torque at standstill. This supports precision positioning and force maintenance without shaft rotation.

What safety mechanism secures the load during system shutdowns or faults?

The 22.0 Nm holding brake locks the shaft when power is off. This prevents unintended motion in vertical or suspended load applications.

How is the motor shaft protected against wear and environmental ingress?

A plain shaft with shaft seal guards against contaminants like dust and fluid. It ensures long-term reliability in industrial machine setups.

Can this model be integrated efficiently into lateral-mounted control cabinets?

Its side B output connector allows optimized cable routing on rear or right-facing installations. This supports cleaner wiring in space-limited enclosures.
