Product Description:

The MHD131D-024-PP0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop industrial axes, it converts drive commands into controlled torque for positioning, conveying, or machining tasks on automated equipment. Because the power leads exit on side B through an output connector, cable routing can remain compact in tightly arranged machine layouts.

With motor size 131 and length code D, the stator and rotor package provides a continuous standstill torque of 160 Nm, allowing the axis to hold heavy loads without external gearing. A centering diameter of 250 mm and a flange dimension of 260 mm simplify mounting to standard machine frames. The keyed shaft transmits torque through a positive mechanical connection, and a shaft seal helps block coolant or dust ingress. The housing is rated IP65, so the windings remain protected in washdown areas and other demanding environments. Encoder feedback is handled by digital servo feedback, which measures position optically and supports absolute counts beyond 4,096 revolutions. The motor is supplied without a holding brake, and winding code 024 matches drive modules that can deliver the rated current at this impedance. Maximum installation altitude is 1,000 m above sea level.

Heat generated in the stator is removed by liquid cooling, allowing full output from 0 to 40 °C ambient without derating and keeping the internal insulation within the limits of class F. The system accuracy of ±0.5 angular minute helps keep multi-axis registration tight during coordinated motion sequences. During storage, the unit tolerates temperatures from -20 to +80 °C without damage to magnets or windings. The absolute position detector eliminates homing after power-up, which can shorten startup time for repeat operations. The coolant path maintains stable operating temperatures during continuous duty.
