Product Description:

The MHD112B-024-NG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a drive element, it converts electrical energy into rotational motion for axis positioning, indexing tables, and handling modules in factory automation. The motor uses relative digital servo feedback through an HSF encoder to report rotor position to the drive controller. It also has a plain shaft for direct coupling to gearboxes or other mechanical loads.

This model delivers a continuous standstill torque of 28.0 Nm, enabling stable force generation when the axis is held at zero speed or moving slowly. An enclosure rating of IP65 seals the housing against dust ingress and water jets, so it can be mounted outside a control cabinet when the surrounding installation is suitable. The mounting flange measures 192 mm for attachment to the machine. Heat generated in the windings is removed through liquid cooling, helping the motor operate within an ambient temperature range of 0 to 40 °C. The motor uses winding code 024, motor length B, and motor size 112. Power conductors are routed to side A through an output connector, and the unit is supplied without a holding brake, so static load retention must be handled at the machine level.

Position repeatability reaches ± 0.5 angular minutes, supporting tight path-following in multi-axis gantries and other coordinated motion systems. Accurate centering on the machine interface is supported by a shaft register diameter of 130 mm. Class F insulation allows the stator to withstand higher winding temperatures during operation. The motor may be installed up to 1000 m above mean sea level without derating. A shaft seal helps protect the front bearing from coolant splash, and the storage temperature range of -20 to +80 °C supports transport and warehouse storage.
