The R911277319 (MHD112D-024-NG0-AN) is a Bosch Rexroth synchronous servo motor engineered for continuous start-stop operation with electrical commutation and low inertia. Key components include a stator, rotor with permanent magnets, sealed bearings, digital servo feedback encoder (HSF), and a plain shaft with seal, achieving IP65 protection. It features a liquid-cooled housing, is specified for a centering diameter of 130 mm, flange size of 192 mm, and continuous stall torque of 48.0 Nm. The design supports a motor size of 112, length D, power connector to side A, and operates in 0 to 40°C ambient environments. The configuration does not include a holding brake.

Why choose a plain shaft with seal on MHD112D-024-NG0-AN instead of a keyed output?

Its sealed plain shaft reduces fretting and ingress to support IP-grade protection and smooth hub clamping. It’s advantageous for washdown-adjacent packaging and food machinery.

What are the implications of “relative” position detection on MHD112D-024-NG0-AN for homing strategy?

The relative encoders require a reference move or marker alignment after power-up to establish absolute machine zero. Its drive typically cache offsets to enable rapid and repeatable homing sequences.

How does power connection oriented to side A on MHD112D-024-NG0-AN aid cabinet and cable routing?

Its side-A orientation allows predictable bend radii and strain-relieved runs in tight envelopes. It reduces EMI coupling paths by enabling short and shield-terminated connectors near the machine backbone.

How does the liquid-cooled housing of the MHD112D-024-NG0-AN affect continuous torque delivery during high duty cycles?

It extracts heat directly from the stator for keeping copper temperatures controlled and resistance drift low. It thermal headroom preserves the rated 48.0 Nm stall torque during sustained throughput.

Which industries typically deploy the MHD112D-024-NG0-AN, and why is it selected there?

Its common uses span machine tools, packaging equipment and food processing lines where precise positioning and start-stop cycles are routine. TIts cooling and encoder pairing supports fast cycles and stable accuracy.
