The MHD112C-058-NG0-AN is a servo motor from Bosch Rexroth Indramat's MHD Synchronous Motors series. It offers continuous torque at standstill of 38.0 Nm and uses liquid cooling. Equipped with a digital servo feedback (HSF) encoder and relative position detection, it features a plain shaft with shaft seal, mounts on a 192 mm flange (centering diameter 130 mm), accepts power via an output connector on side A, has winding code 058, and operates without a holding brake.

Frequently Asked Questions

How does the HSF digital feedback with relative detection in MHD112C-058-NG0-AN affect commissioning and homing?

The relative HSF requires a reference move after power-up to establish machine coordinates while once homed, the loop maintains precise interpolation and phasing. It carries motor/encoder data that streamlines identification and tuning.

What thermal advantages does the liquid-cooled housing of MHD112C-058-NG0-AN provide in continuous-duty automation?

Its circulation removes stator heat more effectively than surface cooling for keeping winding temperatures within design limits during sustained torque delivery. It enables compact installations in warmer enclosures and stabilizes servo tuning across long production cycles.

Why choose a plain shaft with a shaft seal on this MHD series motor?

Its cylindrical shaft supports backlash-free clamping couplings and shrink-fit hubs. When keyed torque transmission is required, select a keyed-shaft variant to minimize fretting and micro-slip.

How does the power-connector orientation to side A on MHD112C-058-NG0-AN influence cable routing?

The side-A orientation keeps harness runs consistent with documented clearances and adjacent components. It also offers other connector directions, while specifying side A simplifies retrofit planning and reduces cable strain in tight frames.

Does the 38.0 Nm continuous stall torque of MHD112C-058-NG0-AN suit machine-tool feed axes?

Yes, this rating covers many medium-duty feed or auxiliary axes where continuous torque and precise velocity regulation dominate requirements over extreme peaks. It validate inertia ratio, duty cycle and cooling flow to ensure margins on your application.

Common Misspellings

Internal Product Review

The Indramat's MHD112C-058-NG0-AN servo motor gets liquid-cooled through its integrated steel ducts and it comes in a frame-112/C-length mechanics. It relies on HSF digital feedback for relative positioning and provides 38 Nm stall torque. This motor has a sealed plain shaft design that is usually employed in printing and machine-tool axes. It provides side-A power connector and 192/130 mm mounting for easy retrofit, while lacks a holding brake in the pre-factory assembly.
