Product Description:

The MHD112B-035-PG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. The model is built for closed-loop positioning and velocity control in automated machinery, where compact torque density and integrated feedback reduce cabinet space and wiring. It combines an optical measurement system with digital servo feedback so the drive controller can track rotor position without external sensors, supporting high-precision axes in packaging lines, transfer stations, and material-handling cells.

The motor’s housing uses liquid cooling, and circulating coolant removes heat directly from the stator, allowing continuous operation at rated load without derating. A continuous standstill torque of 28.0 Nm is the maximum static load the shaft can support while holding position. Environmental sealing meets IP65, protecting internal components from dust ingress and low-pressure water jets during washdown. Mechanical alignment is simplified by a centering diameter of 130 mm, and the flange size is 192 mm, matching standard IEC motor adapters. A plain shaft transmits motion to couplings without a keyway, and electrical power reaches the stator through an output connector mounted on side B, keeping cable routing away from moving machine parts. Motor length B and size 112 indicate the active stack height and frame dimensions used throughout this series.

The allowed running environment spans 0 to 40 °C, while storage between -20 and 80 °C safeguards insulation during transport. Position feedback has a system accuracy of ±0.5 angular minutes, and the encoder provides absolute tracking over more than 4096 revolutions so homing cycles are unnecessary after power loss. The windings use Class F insulation to tolerate internal temperatures up to 155 °C. A shaft seal is fitted to block coolant splash, but no holding brake is installed, so vertical axes must rely on external locking devices. Maximum installation altitude is 1000 m above mean sea level, and the centering features are verified optically to maintain rotor-stator concentricity.
