Product Description:

The MHD112B-048-PP0-AN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. The unit converts drive current from a dedicated controller into controlled mechanical rotation for axes that require high precision and repeatable positioning in industrial automation cells and machine tools. It integrates an absolute encoder and is built for mounting on a liquid-cooled flange interface used on compact, high-power servo axes. This arrangement supports precise positioning, contouring, and stable speed control in automated machinery.

During continuous stall conditions, the rotor can supply 28.0 Nm without overheating, giving the system a predictable torque limit for holding or low-speed feed moves. Thermal energy is removed through liquid cooling, allowing higher power density than natural-convection housings of the same frame size. The mechanical connection uses a 192 mm square flange, and a 130 mm centering diameter keeps the housing concentric to the driven load to help reduce radial misalignment. Position and velocity data are returned through integrated digital servo feedback, which communicates directly with compatible Rexroth drives and supports fine interpolation for synchronized multi-axis motion.

Electrical energy reaches the stator windings through an output connector located on side A, so cable routing can stay parallel to the machine backbone and experience less bend stress. The rotor transmits torque through a keyed shaft, and a shaft seal helps block oil or coolant from entering at the bearing journal. Absolute position values remain valid for more than >4096 revolutions, which reduces the need for homing after power is restored. Winding code 048 and the B length code indicate the electrical characteristics and stack depth used for drive matching and thermal balance.
