The Rexroth Indramat MPN R911296837 (MHD112B-048-PG2-BN) is a brushless synchronous servo motor featuring liquid-cooled housing and a plain shaft with seal. It incorporates digital servo feedback with an integrated encoder enabling absolute position detection over more than 4096 revolutions. This motor has a continuous torque at standstill of 28.0 Nm and is equipped with a holding brake rated at 32.0 Nm. The motor measures 192 mm at the flange, has a centering diameter of 130 mm, and is classified as size 112, length B. The power connection is located on side B via an output connector. Operation above 1000 meters altitude or ambient temperatures exceeding 45°C is not recommended. Cooling is achieved primarily by natural convection, and an external air blower can be added for enhanced heat dissipation.

Frequently Asked Questions

What protects the MHD112B-048-PG2-BN’s shaft from damage in particle-heavy environments?

The sealed shaft design blocks contaminants from entering the drive system. This improves reliability in dust-prone or fluid-exposed applications.

Can this motor maintain performance under continuous load without overheating?

Its liquid-cooled housing removes thermal buildup during sustained duty cycles. This ensures consistent output without derating in temperature-sensitive installations.

Is precise positioning preserved across system restarts without re-homing?

A digital encoder with absolute detection over 4096+ revolutions tracks position without power loss. This supports uninterrupted control in automated cycles.

How does the MHD112B-048-PG2-BN ensure positional security when power is lost?

It integrates a 32.0 Nm holding brake to lock the shaft during shutdown. This prevents drift or load drop in critical static applications.

Will this motor mount directly into standard drive assemblies without custom fitting?

Its 130 mm centering diameter and 192 mm flange match industrial servo standards. This enables consistent alignment across modular automation platforms.
