Product Description:

The MHD112B-035-NG0-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It converts three-phase drive power into precise rotary motion for indexing tables, handling modules, and packaging axes on automated lines. Winding code 035 and size 112 identify the electromagnetic build and frame class used for this motor. This makes the unit suitable for axes that require accurate speed control and repeatable positioning during continuous production.

The motor mounts to machinery through a centering pilot of 130 mm, ensuring coaxial alignment with the flange. At standstill, it delivers a continuous torque of 28.0 Nm, allowing static load holding without thermal overload when liquid flows through the jacket. Its housing is sealed to IP65, so airborne dust and water jets do not reach the stator laminations. Internal heat is carried away by liquid cooling, which supports full-rated output inside dense cabinets. High-resolution feedback derived from an optical track yields a system accuracy of ± 0.5 angular minutes, and relative position data are transmitted by a digital HSF encoder to the drive controller. The digital feedback channel allows the connected drive to monitor rotor position continuously during motion.

Storage and handling are permitted between -20 to +80 °C, while operation is limited to 0 to 40 °C and up to 1000 m above mean sea level. The square mounting face measures 192 mm and uses a plain shaft with a shaft seal to help keep lubricant inside the housing and reduce contaminant entry around the shaft opening. Insulated to class F, the stator tolerates winding temperatures associated with continuous full-load duty. The motor is shipped without a holding brake, so external clamping must secure vertical loads. Power and feedback plugs point to side A through an output connector. The compact B-length housing also helps the motor fit into space-limited installations.
