MHD131D-024-PP2-BN

The Bosch Rexroth Indramat MHD131D-024-PP2-BN servo motor, part of the MHD Synchronous Motors series, delivers a robust combination of high torque density and precise position feedback. This Servo Motor features an integrated multiturn absolute encoder with digital servo feedback, ensuring reliable detection beyond 4096 revolutions for critical motion control tasks. Equipped with a with holding brake mechanism and a holding brake torque of 240 Nm, the unit secures the load during power-off or emergency stops. Its keyed shaft design simplifies mechanical coupling while the keyed output shaft maintains alignment in demanding automation systems. As a permanent magnet motor, it supports both natural convection and surface cooling modes to match diverse application requirements.

The MHD131D-024-PP2-BN is engineered to exacting standards with key parameters including a Motor Size of 131 and Centering diameter of 250 mm on a Flange size of 260 mm. The motor flange uses a Keyed Shaft output with an integrated Shaft Seal to protect internals from contaminants. Electrical connection is handled via an Output Connector directed to side B, supporting supply voltages from 177 V to 279 V through the B-side power connector. The winding system uses the Winding Code 024 with an inductivity of 2.5 mH and a resistance of 0.08 Ω at 20 °C to optimize current control. The housing employs Liquid cooling for higher thermal capacity, while the product meets IP65 ingress protection for reliable operation in harsh environments.

Operational performance is characterized by a peak speed of 3000 rpm delivering a maximum torque of 448 Nm at a peak current of 398 A. Under steady conditions with a 60 K rise in housing temperature, the motor produces a continuous torque of 160 Nm at a continuous current of 88.4 A; at 100 K winding temperature rise it delivers 240 Nm continuous torque at 132.6 A continuous current. Natural convection cooling yields a rated power of 7 kW, while surface cooling boosts output to 26.5 kW. The four-pole-pair design ensures smooth torque delivery, and the multiturn absolute encoder provides deterministic feedback for closed-loop control.

System integration is streamlined through standard interfaces and compatibility with Rexroth Indramat digital drive controllers, supporting real-time tuning and diagnostic functions. The compact Motor Length D and standardized flange allow drop-in replacement in existing machine designs, and the integrated holding brake simplifies safety circuit design. Target applications include CNC machining, industrial robotics, packaging lines, and material handling systems where precise positioning, high torque, and robust environmental protection are essential.
