Product Description:
The MHD112C-035-NP3-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator for industrial automation, it converts drive-controller current into precise mechanical motion for positioning tables, gantries, or processing spindles. The keyed shaft, liquid-cooled housing, and output connector on side A support installation in machines that demand continuous duty cycles and accurate speed control. This layout also helps keep the motor compact around the machine interface while leaving room for power and feedback connections in tightly arranged assemblies.
This model sustains a continuous standstill torque of 38.0 Nm, allowing it to hold or start heavy loads without additional gearing. Its enclosure is rated IP65, keeping internal components free from dust ingress and low-pressure water jets. Mounting follows a square flange pattern measuring 192 mm, while a pilot diameter of 130 mm centers the stator to the driven equipment and helps reduce radial misalignment. Heat generated in the windings is removed by liquid cooling, so output can be maintained without relying on ambient airflow. The motor operates without derating between 0 to 40 °C, which suits typical plant conditions. A digital servo feedback encoder of the HSF type reports rotor angle to the drive, and winding code 035 identifies the electrical characteristics used with matching power modules.
For safety during power loss or emergency stops, the integrated brake clamps the shaft with 70.0 Nm of torque. Feedback resolution and internal optics yield a system accuracy of ± 0.5 angular minutes, supporting repeatable positioning in indexing or contour-following tasks. Windings built to class F insulation tolerate hotspot temperatures up to 155 °C during operation. Additional features include a shaft seal that helps block lubricant migration, relative position detection suited to homing routines, and permitted installation elevation up to 1000 m above mean sea level. These operating features make the motor suitable for axes that need stable holding, repeatable motion, and dependable thermal performance during extended use.
