Product Description:

The MHD112B-035-PP0-LN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It suits installations that use the 112 frame size and compact B length code, while winding code 035 sets the electrical characteristics for matching drive operation. A keyed shaft transmits mechanical power, and a sealed power connector on the left side of the housing provides the supply connection. The motor is delivered without a holding brake, so static loads must be secured by external means. Rotor position is sensed optically by a digital servo feedback encoder that provides absolute data for more than 4,096 revolutions, supporting precise closed-loop motion control during positioning and speed regulation.

This model delivers a continuous stall torque of 28.0 Nm, allowing it to maintain load at standstill in direct-drive or lightly geared applications. Thermal energy is removed through a liquid cooling jacket, which helps keep output stable within an ambient range of 0 to 40 °C. The enclosure is rated IP65, which helps keep dust and water jets away from the windings and bearings. Closed-loop accuracy is supported by a system deviation limited to ± 0.5 angular minutes, helping the motor track commanded positions with tight repeatability in synchronized multi-axis equipment.

Mechanical integration uses a centering diameter of 130 mm and a square flange measuring 192 mm, which supports accurate alignment on compatible machine interfaces. The windings use insulation rated to Class F, and a shaft seal is fitted to help protect internal parts from coolant splash and similar contamination. Installation is permitted up to 1000 m above mean sea level. Long-term storage between −20 and +80 °C helps protect materials and insulation before the motor is placed into service.
