Product Description:
Bosch Rexroth Indramat’s MHD112B-058-PP0-BN is a servo motor in the MHD Synchronous Motors series. The unit converts electrical energy from a drive controller into controlled rotary motion for positioning and speed-regulated tasks on automated machinery. It is suited for packaging lines, material handling axes, and other motion platforms that require closed-loop regulation. Because feedback is integrated into the motor package, the connected drive can correct speed deviations and maintain repeatable motion under changing loads.
The motor develops a continuous standstill torque of 28.0 Nm, allowing static load support without overheating. Thermal dissipation is aided by liquid cooling, so rated output can be maintained even when mounting density is high. This cooling method helps move heat away from the housing during sustained operation. The motor uses a 130 mm centering diameter and a square flange that spans 192 mm, so it matches corresponding gearbox or machine frame openings. The flange format also helps keep the shaft centered during installation, which supports accurate coupling alignment and smoother torque transfer to the driven mechanism. Its winding code is 058, which corresponds to the electrical characteristics used with the designated drive module. With frame size 112 and motor length code B, the stator depth balances inertia and torque for medium-duty cycles.
Position feedback is supplied by digital servo feedback with an integrated encoder that provides Absolute (>4096 revolutions) resolution, eliminating the need for homing after power restoration. Power enters through an output connector on side B, a layout that simplifies cable routing inside vertical cabinets and other tight installations. That connector position can also reduce cable bending near the housing when the motor is mounted close to guards or frame members. The motor employs a keyed shaft for positive mechanical locking, and it includes a shaft seal that helps block lubricant migration. There is no built-in holding brake, so external clamping or motor torque must secure loads when power is removed. The sealed housing supports closed coolant circulation and helps protect the internal feedback electronics from moisture.
