Product Description:
The MHD112B-048-PP0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In automated production cells, this motor converts drive controller commands into precise rotary motion for conveyor, tooling, and positioning axes that require synchronized velocity and torque control. Its electrical characteristics are matched to Indramat drive controllers used in medium-power machine tools, packaging lines, and material-handling stations.
Its centering shoulder measures 130 mm, allowing straightforward alignment with machine frames that share this pilot diameter, while the square mounting flange spans 192 mm for standardized bolt patterns. When energized, the rotor delivers 28.0 Nm of continuous torque at standstill, which indicates how much static load the axis can support without overheating during closed-loop holding. Heat generated under that load is removed by liquid cooling, so the motor can sustain output in sealed cabinets or at elevated ambient temperatures without derating. Position data for the drive comes from the integrated encoder, which provides digital servo feedback with the absolute and incremental signals required for commutation and fine motion control. The unit ships without a holding brake, and its B length code denotes the second shortest stator stack within the 112 frame size.
The mechanical interface uses a keyed shaft so torque is transferred through a positive drive element rather than relying solely on clamping friction, and a shaft seal is installed to restrict lubricants or coolant from entering the bearing area. The power cable exits the housing on side B, simplifying routing when the motor rear faces electrical enclosures. The encoder supports absolute feedback over more than 4096 revolutions, removing the need for homing sequences after power is restored. Electromagnetic parameters are tied to winding code 048, enabling the paired drive to apply the correct resistance and inductance tables so current regulation matches the thermal limits of this winding set.
