Why are the keyed shaft (DIN 6885) and shaft seal important under reversing loads?

The standardized keyway geometry (balanced with the entire keyway) improves torque transmission and alignment for limiting micro-slip during bi-directional transients. Its seal helps protect bearings/feedback from oils, emulsions and dust typical of factory environments.

What thermal advantages does liquid cooling provide in MHD112C-058-NP0-AN during continuous duty?

It extracts stator losses directly for maintaining uniform winding temperatures and enabling torque near its 38.0 Nm stall figure. Its extra thermal margin supports steadier speed regulation and mitigates derating in enclosed machine bases.

How does HSF digital servo feedback with relative detection impact commissioning on the MHD112C-058-NP0-AN?

The HSF gives 4,194,304 counts/rev and ±0.5 arc-minute accuracy to enable precise commutation and stable low-speed control. Its position isn’t retained after power-off, so the axis must reference at startup.

What does “power connection to side-A” mean for cable routing on MHD112C-058-NP0-AN?

The connector orientation can be specified to side A, side B, right or left at order time. It shortens cable runs in left-mounted cabinets and reduces bend-radius stress on motor leads.

How does the brushless, electronically commutated design of the MHD series influence service intervals?

The brushless operation eliminates brush wear and the sealed IP65 architecture with lifetime-lubricated bearings significantly reduces scheduled maintenance. Its design supports long uptime in dusty or oily production areas with minimal intervention.

Bosch Rexroth produces the servo motor MHD112C-058-NP0-AN with a keyed-and-sealed shaft. It uses an inbuilt feedback encoder for relative motion and speed detection. This unit has a 38.0 Nm stall torque capability and its constructed form is 192 mm/DIN flange with 130 mm pilot. It provides side-A power connection for simplifying retrofits. Its brushless architecture lowers upkeep that makes it suitable for packaging, printing, textiles and machine-tool axes.
