Product Description:

The MHD112A-024-PG0-AN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical energy from a drive controller into regulated mechanical motion for conveyors, tooling axes, and assembly stations in automated lines. The motor is supplied without a holding brake, and its length corresponds to size A in the 112 frame.

The motor can deliver a continuous standstill torque of 15.0 Nm, allowing sustained holding or low-speed feed tasks without overheating. Thermal energy is removed by liquid cooling, which circulates through the housing and supports operation even in confined cabinets. The stator windings and enclosure meet IP65, so dust ingress and water jets do not affect internal components. Mechanical integration is simplified by a 130 mm centering diameter on a 192 mm square flange, while the power cable exits toward side A through an output connector. A plain shaft transmits torque directly, and a shaft seal is fitted to guard the bearing chamber. Position data are captured optically by the integrated digital servo encoder, which provides absolute feedback for more than 4096 revolutions.

The feedback chain supports system accuracies of ±0.5 angular minutes, so the axis can meet fine tolerance requirements. Class F insulation permits standard winding temperatures, and continuous service is allowed from 0 to 40 °C ambient when the coolant loop is active. Winding code 024 indicates the electrical resistance and inductance set expected by the Indramat drive modules. For storage or transport, the motor remains stable between -20 and +80 °C, and installation is permissible up to 1000 m above mean sea level without derating. Absolute position detection removes the need for homing after power loss, and the sealed housing accepts dedicated coolant fittings to preserve the IP rating during service.
