Product Description:

The MHD131D-024-NP0-AN is a servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. In automated cells, it couples to a regulated drive controller so commanded current generates proportional torque for tool changers, gantries, or press feeds that demand repeatable motion profiles. A permanently excited rotor, a liquid-cooled stator jacket, and digital position feedback allow the unit to maintain commanded speed or angle under dynamic load changes common in industrial automation.

During standstill, the motor can deliver a continuous torque of 160 Nm, providing high holding capacity for axis groups that must resist process forces without excess current draw. The IP65 protection class seals the housing against dust and low-pressure water jets, so electrical windings remain dry when the machine enclosure is cleaned. Heat is extracted through liquid cooling, permitting sustained output without derating in tight cabinets. A centering pilot of 250 mm aligns the 260 mm flange precisely to the machine frame, minimizing radial runout. System positioning error is limited to ± 0.5 angular minutes because the optical measurement method monitors rotor position relative to the stator field.

The motor operates in ambient air from 0 to 40 °C and relies on digital servo feedback (HSF) for high-speed commutation and real-time diagnostics. Its output shaft ensures slip-free power transmission, and the mechanical interface is a keyed shaft. Windings use Class F insulation for thermal endurance, and a shaft seal is fitted to block coolant ingress. The design omits a holding brake, so static locking must be supplied externally. The motor uses relative position detection. Motor size 131, length code D, and winding code 024 set its electrical characteristics. Installation is allowed up to 1000 m above mean sea level. Power cables exit on side A through an output connector, and the unit may be stored between −20 °C and 80 °C without performance loss.
