Product Description:

The MHD112B-035-PP0-AN is a servo motor supplied by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. In industrial automation, this unit converts drive-controller commands into precise mechanical rotation for tasks such as feed-axis positioning, tool orientation, or conveyor indexing in automated machinery. Absolute position detection over more than 4096 revolutions is handled by a built-in digital servo feedback encoder, so the controller knows the rotor angle at startup without needing a homing move.

At the mechanical interface, the motor can supply 28.0 Nm of continuous torque when stopped, enough for medium-inertia loads that require firm holding force before motion begins. Heat generated during operation is removed through liquid cooling instead of airflow, so rated output can be maintained even inside sealed cabinets. The housing carries an IP65 rating, which blocks dust and low-pressure water jets that are common near machining coolant or washdown stations. Operation is permitted at ambient temperatures from 0 to 40 °C without derating in typical shop-floor conditions. A square mounting flange of 192 mm mates directly to standard machine frames and helps simplify installation.

The unit’s servo accuracy is backed by a system deviation of ± 0.5 angular minutes, supporting multi-axis interpolation without noticeable contour error. Shaft concentricity is aided by a centering diameter of 130 mm, and power is transmitted through a keyed shaft that helps prevent slip during torque reversal. Installation is permitted up to 1000 m above mean sea level, so elevation does not affect insulation or cooling limits. The motor has a liquid-tight shaft seal, F-class winding insulation, optical measurement in the encoder, and a power connector routed toward side A. It is shipped without a holding brake for applications that already use external clamping devices.
