Product Description:
The MHD112B-058-PG1-AN is a servo motor built by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As a brushless AC drive element, it converts electrical energy from a matched inverter into controlled rotary motion for positioning and feed axes in automated machinery. The motor belongs to size 112 with length code B, and winding code 058 sets the electrical characteristics for mid-range speed and torque demands in production equipment. In closed-loop motion systems, this arrangement helps the connected drive respond smoothly to changing loads and commanded speed changes.
At stall, the rotor can develop a continuous torque of 28.0 Nm, giving the axis solid force for holding and low-speed process work without excessive thermal stress. Mechanical centering during installation is simplified by the 130 mm pilot diameter, and the square mounting face matches a flange of 192 mm, which fits common motor adapter patterns. Thermal loading is controlled by liquid cooling channels in the stator housing, allowing higher continuous current than similarly sized motors that rely only on ambient air. Power conductors terminate in an output connector mounted on side A, which helps keep cable routing orderly inside compact machine frames. A digital servo feedback system is integrated for real-time speed and position data, and the shaft seal helps reduce the risk of coolant or oil entering the bearing area.
The integral holding brake supplies 22.0 Nm of mechanical holding torque to keep the axis in place when drive power is removed. The feedback system stores an absolute (>4096 revolutions) reference, so multi-turn position information remains available after shutdown and restart. Torque is transmitted through a plain shaft, which works well with precision hubs and other backlash-conscious coupling elements. The shaft seal also supports use in machine areas where moisture, coolant mist, or light oil exposure is common.
