Product Description:
Bosch Rexroth Indramat manufactures the MHD131D-024-PP2-BN, a servo motor in the MHD Synchronous Motors series for medium-to-high power automation. It converts drive controller commands into controlled rotary motion through a keyed shaft, serving tasks such as feed axes and handling gantries. It is intended for precise rotary positioning where the drive must regulate speed, torque, and final shaft angle under changing load conditions. The size 131 frame uses a 260 mm square flange and seats on a 250 mm centering diameter, while length code D indicates a deep stator stack for higher electromagnetic output. Absolute position data for more than 4096 turns is captured optically by a digital servo feedback encoder integrated into the rear end bell.
At standstill, the motor can deliver a continuous torque of 160 Nm. This output is sustained by liquid cooling through the stator jacket, which stabilizes winding temperatures so the F-class insulation stays within its thermal range. A normally closed brake provides a holding capability of 240 Nm when power is removed, which helps secure vertical axes during stops. The housing is sealed to IP65 so coolant spray, dust, and oil mist cannot reach internal laminations, supporting ±0.5 angular-minute closed-loop precision. Power is fed through an output connector on side B, and winding code 024 is intended for use with compatible drive electrical data.
For correct operation, the motor must run within an ambient range of 0 to 40 °C and may be stored between -20 to +80 °C without degradation. Installation heights can reach 1000 m above MSL before derating becomes necessary. A factory-installed shaft seal blocks contamination along the output journal, and the coolant circuit can be purged without dismantling the housing. The cooling path can also be filled and vented during machine integration without opening the motor. These features support reliable operation in enclosed equipment where clean running surfaces and stable thermal behavior are important.
