Frequently Asked Questions

What is the role of the HSF digital servo feedback interface on this motor?

The HSF is Bosch Rexroth’s encoder interface used on MHD motors. It ensures deterministic position/velocity data exchange with IndraDrive controllers. The MHD112C-035-NP0-BN uses HSF for precise relative position detection and stable servo loops with low phase lag.

How do the 192 mm flange and 130 mm centering diameter affect mechanical integration?

These standardized interfaces deliver concentricity and radial stiffness for improving coupling alignment and reducing runout-induced vibration. Its integrators can reuse existing 192/130 tooling plates for shortening retrofit timelines for the MHD112C-035-NP0-BN across machine families.

What mounting and shaft features aid torque transmission on MHD112C-035-NP0-BN?

Its keyed shaft per DIN-style geometry with a sealing ring provides positive drive and contamination control. Its geometry resists micro-slip under dynamic torque reversals for protecting couplings and maintaining backlash targets in precision axes.

How does the side-B power-connector orientation influence cabinet and cable routing?

The connector exiting on side B provides segregated from feedback lines and machine guarding on many right-hand mounting schemes. It simplifies EMC grounding layout and bend-radius planning in tight enclosures.

How does the 38 Nm continuous standstill torque translate to axis sizing for MHD112C-035-NP0-BN?

It determines achievable clamping/following force at zero speed for guiding gearbox ratio and ballscrew lead choices. Its torque margin allows tighter current limits to reduce thermal drift and enhances repeatability over long dwell segments.
