Product Description:

The MHD112C-035-NP0-LN is a three-phase AC servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It delivers closed-loop axis motion for machining centers, handling modules, and transfer lines where repeatable rotary movement is required. The motor uses a keyed shaft for positive torque transfer, and a shaft seal helps limit coolant ingress at the output end. Digital servo feedback is obtained optically for relative position monitoring, and size code 112, length code C, and winding code 035 indicate the frame and electrical layout. The power connector exits to the left, which can simplify cable routing where adjacent machine elements limit access on the opposite side. This layout is useful on compact axes where cable bends must stay controlled near guards or slides.

At the mechanical interface, a flange pattern of 192 mm mates with standard IEC gearboxes, and the centering register helps maintain concentric alignment during installation. The housing is cooled by liquid cooling, so thermal losses are removed without relying on ambient airflow. Under continuous excitation, the motor develops 38.0 Nm of torque at standstill, even though it is supplied without a holding brake. The enclosure carries a protection rating of IP65, providing dust-tight construction and resistance to water jets when the front power connector is engaged. High-resolution feedback limits total system error to ± 0.5 angular minutes, and the left-oriented connector helps keep cabling clear of moving linkages.

For installations subject to temperature changes, allowable storage spans -20 to +80 °C, and service operation is permitted between 0 to 40 °C without derating. Class F insulation allows the winding system to tolerate elevated internal temperatures, while the liquid-cooling circuit removes heat during sustained duty. A maximum installation altitude of 1000 m above mean sea level is permitted. A centering diameter of 130 mm provides a rigid pilot fit with the mounting surface and supports precise alignment of the keyed shaft with couplings. These operating limits suit machine installations that see routine ambient variation between storage and production.
