Product Description:

The MHD112D-024-PP3-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Intended for closed-loop positioning and speed regulation on production machinery, presses, and material-handling axes, the unit converts drive commands into precise shaft motion. By combining digital feedback with a liquid-cooled stator, the motor delivers stable torque in compact installations and supports accurate motion in precision automation systems. This operating concept is useful on axes that must respond consistently to changing loads and repeated start-stop cycles.

At the rotor, the machine sustains a continuous standstill torque of 48.0 Nm, keeping heavy tables motionless without external clamps. A built-in brake locks the shaft with 70.0 Nm when the drive is disabled. The housing is sealed to IP65, blocking dust and low-pressure water jets, while internal channels circulate coolant; this liquid cooling removes heat even at full load. The mechanical interface uses a 192 mm square flange and a 130 mm centering pilot that aligns the motor on the machine frame. Power exits on side A through an output connector, and the keyed shaft with a shaft seal transmits torque while helping keep lubricant contained.

Digital servo feedback with an integrated optical encoder provides absolute position information beyond 4096 turns, delivering a system accuracy of ± 0.5 angular minutes for fine interpolation in multi-axis gantries. Safe operation is permitted from 0 to 40 °C, and storage or transit can endure temperatures from -20 to +80 °C without insulation damage; Class F windings tolerate internal hot spots up to 155 °C. The unit may be installed up to 1000 m above mean sea level without derating. Its digital feedback allows compatible drives to evaluate rotor position directly for stable low-speed control and precise positioning.
