Product Description:

The MHD112B-048-NG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It supplies closed-loop axis actuation for packaging lines, machine tools, and material-handling cells. The motor has size 112 and length code B for a mid-frame geometry, while winding code 048 matches the stator to the required drive current. By converting commanded position data into rotary motion and returning precise feedback, the unit supports repeatable motion cycles without auxiliary gearing. The integrated feedback lets the connected drive correct position and speed deviations during operation.

At standstill, the rotor delivers 28.0 Nm of continuous torque, allowing it to hold a steady load without thermal overload under rated conditions. Heat is removed through liquid cooling, which helps control housing temperature while the motor remains sealed. The enclosure is rated IP65, which resists dust ingress and water jets in washdown areas. Position data comes from digital servo feedback (HSF) with optical scanning, providing a system accuracy of ± 0.5 angular minutes for precise contouring. The motor is supplied without a holding brake, so vertical axes need external clamping or drive torque when power is off.

A square flange measuring 192 mm and a pilot diameter of 130 mm help keep the shaft aligned with the driven load during installation. The motor uses a plain shaft with a shaft seal to limit lubricant migration and help protect the bearing area. Copper windings use Class F insulation, and the allowable ambient operating range is 0 to 40 °C; operation outside this range requires derating. Storage is permitted from -20 to +80 °C, and installation is supported up to 1000 m above sea level. Power enters through a connector on side B of the housing, which can simplify cable routing where rear clearance is limited.
