Frequently Asked Questions

Why is the 192 mm flange and 130 mm centering diameter relevant for machine retrofits?

These interfaces match common Rexroth MHD mounting patterns for simplifying adapter-plate design and maintaining shaft-to-load concentricity. Its fit-up is predictable across gearboxes and belt drives for reducing alignment time in brownfield upgrades.

How does the keyed, sealed shaft on MHD112C-035-PP0-BN affect coupling selection and contamination control?

It simplifies torque transmission with standard taper-lock or jaw couplings, while the shaft seal limits ingress during washdown or dust exposure. It maintains coupling life and encoder signal integrity in harsher cells.

What role does the integrated digital servo feedback with multiturn absolute detection (>4096 rev) play in commissioning and restart behavior?

The encoder preserves multi-turn position without homing after power loss, so MHD112C-035-PP0-BN axes can resume coordinated motion quickly and consistently. It reduces cycle downtime to avoid fixture re-touch and improves safety interlocks that rely on absolute position certainty.

How does liquid cooling in the MHD112C-035-PP0-BN influence duty cycles and thermal headroom versus surface-cooled variants?

It shuttles stator losses directly to the housing for allowing higher continuous torque density at a given frame and steadier winding temperatures during rapid cycling. It enables longer continuous operation near thermal limits and mitigates drift in position loops under sustained load.

What integration advantages come from the side-B power connection and output connector format on MHD112C-035-PP0-BN?

It eases cable routing in multi-axis machines for minimizing bend-radius conflicts and electrical noise coupling. Its standardized connector geometry accelerates field replacement and maintains ingress protection on the motor face.

Internal Product Review

The MHD112C-035-PP0-BN servo motor from Rexroth comes in a liquid-cooled housing and it has a 192 mm flange/130 mm pilot. It is accompanied by a keyed shaft design with an imposed sealing ring for protection. This motor has built-in digital servo feedback that provides multiturn absolute position detection. Its winding is designed for 38 Nm of stall torque and it supports side-B power connection. It lacks any holding brake assembly and its design makes it suitable for packaging, printing, textiles and indexing roles.
