Product Description:

The MHD112B-035-NG0-BN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. This electromechanical unit fits into digitally controlled drive systems where precise rotary positioning, velocity tracking, and holding torque are needed on machine tools, printing lines, and automated material-handling equipment. By combining a stator winding matched to the 035 code with a size-112 frame, the motor provides a compact, high-torque solution that can be paired with compatible Indramat drive controllers across a wide automation platform.

At the core of its performance is a continuous standstill torque of 28.0 Nm, giving machine axes stable force even when zero speed is commanded. The enclosure has an IP65 rating, which helps keep dust and low-pressure water jets out of the internal laminations. Heat generated by losses is removed through liquid cooling, so the stator can remain within thermal limits during sustained heavy-duty operation. Rotor position is reported by a digital servo feedback (HSF) encoder that supplies high-speed incremental signals to the drive controller. This arrangement supports a system accuracy of ± 0.5 angular minutes for fine contouring and synchronized multi-axis motion.

In regular operation, the unit functions in ambient air from 0 to 40 °C, and storage is permitted from -20 to +80 °C. Mounting is guided by a centering pilot of 130 mm and a square flange width of 192 mm, which provides a repeatable mechanical reference on gearheads or machine frames. Installations up to 1000 m above mean sea level are supported without derating. The motor also uses F-class insulation, an optically based relative measurement method, a plain shaft with an integral seal, and a side-B power connector. It is supplied without a holding brake.
