Product Description:

The MHD112B-035-PP1-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It is intended for industrial automation axes where constant torque and responsive positioning are required, such as packaging stations, gantry drives, and transfer lines. The model integrates a keyed shaft and a shaft seal to help block fluid ingress while allowing direct mechanical coupling to downstream components. Its housing is prepared for liquid circulation so the motor can sustain continuous operation during extended duty cycles.

This unit delivers a continuous standstill torque of 28.0 Nm, which is the torque the rotor can hold at standstill when energized. An enclosure rating of IP65 protects the internal windings from dust and low-pressure water jets, allowing installation close to the working zone. Heat generated by copper losses is removed by liquid cooling; coolant flows around the stator jacket to help keep winding temperature within the Class F limit. A square flange measuring 192 mm helps align the motor with standard gearboxes and motor adapters, and the integrated brake applies 22.0 Nm of holding torque to secure vertical loads when the drive is disabled.

For precision control loops, the optical feedback system offers a system accuracy of ± 0.5 angular minutes, which helps reduce following error in contouring applications. Mounting concentricity is assisted by a 130 mm centering diameter, which helps center the motor on the machine frame and reduce radial misalignment. Position detection is absolute (>4096 revolutions), so power cycles do not erase the multiturn count and homing routines can be shorter. Rated operation is permitted over 0 to 40 °C; outside this range, the motor requires derating or additional cooling. Additional data includes insulation Class F, a maximum installation height of 1000 m above mean sea level, and a power connector oriented toward side A to support common cabinet layouts.
