The R911287749 (MHD112C-024-PG3-RN) is a Rexroth Indramat synchronous servo motor equipped with a liquid-cooled housing and digital servo feedback with an integrated encoder, providing absolute position detection over more than 4096 revolutions. It is a brushless motor with electronic commutation, designed for frequent start-stop cycles and quiet, efficient operation. The motor incorporates a plain shaft with a shaft seal, a 130 mm centering diameter, and a 192 mm flange. It delivers 38.0 Nm of continuous torque at standstill and is fitted with a holding brake rated at 70.0 Nm. The power connector is oriented to the right. The unit operates in ambient temperatures from 0 to 40°C and can be stored up to 80°C.

What positioning feedback does the MHD112C-024-PG3-RN provide, and how does it aid multi-axis synchronization?

It uses digital servo feedback with a multiturn absolute encoder for tracking over 4096 revolutions to preserve position through power cycles. It enables deterministic homing and tighter electronic gearing in coordinated packaging or printing lines.

What role does the 70 Nm holding brake play on the MHD112C-024-PG3-RN in vertical axes or safety-related stops?

The integrated brake supplies static torque to hold loads when power is removed for preventing drift on Z-axes or elevators. It complements drive-based STO functions by mechanically securing position during E-stops.

How does liquid cooling on MHD112C-024-PG3-RN influence continuous torque delivery and enclosure design?

The liquid cooling removes heat directly from the stator for enabling higher continuous torque at standstill (38 Nm) without enlarging the frame. It also helps maintain sealed housings in washdown or dusty conversion machinery.

How do the 130 mm centering diameter and 192 mm flange simplify mechanical interchange for brownfield upgrades?

These standardized MHD112C mounting interfaces allow adapter-plate-free swaps on many legacy machine tools and packaging stations. Its plain shaft with seal eases coupling alignment while maintaining ingress protection.

What wiring orientation and connector style are used on many MHD112C-024 variants, and how does that aid panel layout?

It uses a right-oriented power connector that routes cabling away from guard doors and coolant manifolds. It reduces bend-radius conflicts and eases service access.
