The R911277119 (MHD112D-024-NP0-AN) is a Bosch Rexroth MHD synchronous AC servo motor with a frame size of 112 and motor length D. It features a self-cooling design relying on natural convection or optional surface cooling, and is rated for IP65 environmental protection. The unit does not include a holding brake and utilizes a keyed shaft with shaft seal. The digital servo feedback encoder (HSF) offers relative position detection with system accuracy of ±0.5 angular minutes. Mechanical interface measures include a centering diameter of 130 mm and a flange size of 192 mm, with continuous torque at standstill specified at 48.0 Nm. The stator winding is identified by code 024, and the insulation system meets DIN VDE 0530 class F. Power is connected via an output connector oriented to side A.

Frequently Asked Questions

How does the side-A power connector orientation simplify machine wiring and service loops for MHD112D-024-NP0-AN?

The side-A routing keeps power conductors clear of feedback cabling for aiding EMC segregation and bend-radius management inside tight enclosures. It also supports accessible service loops to reduce connector fatigue during maintenance or axis teardown.

Is MHD112D-024-NP0-AN compatible with Bosch Rexroth drive controllers used across packaging or printing lines?

Yes, this model is designed to pair with Rexroth drive controllers specified for the MHD series; confirm firmware and parameter sets during commissioning. It is used in packaging, printing, paper and machine-tool installations.

How do the keyed shaft and shaft seal enhance coupling integrity on the MHD112D-024-NP0-AN?

Its keyed interface transmits torque with precise angular registration for resisting micro-slip at high reversal rates. Its shaft seal limits ingress of particulates and splash for helping preserve bearing life and feedback stability in production environments.

How do the 130 mm centering diameter and 192 mm flange size influence retrofit and alignment tasks?

These dimensions provide a stable pilot and bolt pattern that aid concentricity and squareness when mating to gearheads or machine frames. Its standardized interface eases drop-in replacement within the MHD family and many legacy Rexroth layouts.

What advantages does Digital servo feedback (HSF) with relative position detection provide on this motor?

The HSF feedback delivers fine velocity/position granularity and low-latency updates to the drive for improving contour accuracy and speed regulation. Its relative detection simplifies homing strategies and allows deterministic referencing routines without the cost/complexity of multiturn absolute encoders.
