MHD112B-048-NP1-AN

The Bosch Rexroth Indramat MHD112B-048-NP1-AN is a high-performance servo motor in the MHD Synchronous Motors series, designed for demanding industrial motion control. This Servo Motor features a robust housing with liquid cooling capability, ensuring stable operation under heavy loads. The motor integrates a Digital servo feedback (HSF) encoder and supports relative position detection, delivering precise feedback for closed-loop control. Equipped with a keyed shaft and shaft seal, the MHD112B-048-NP1-AN offers reliable mechanical coupling and environmental protection. A built-in 22.0 Nm holding brake adds fail-safe torque retention for vertical or emergency stop applications.

The MHD112B-048-NP1-AN’s detailed specifications span mechanical, electrical, and interface parameters. The Flange size of 192 mm and Centering diameter of 130 mm match standard mounting interfaces, while the Keyed Shaft design and shaft diameter of 32 mm facilitate secure coupling. Its Winding Code of 048 defines the internal coil configuration, driving a Continuous Torque at Standstill of 28.0 Nm and a Maximum Torque output of 102 Nm. Electrical interfaces include a Power Connection Type: Output Connector on side A and a separate feedback connector for the encoder. The motor’s Motor Size of 112 and Motor Length designation "B" specify its form factor, and a total motor length of 375 mm accommodates space planning. The housing meets IP65 protection and features a matte black finish for corrosion resistance.

Operationally, the motor delivers a Rated Speed of 2800 RPM and peaks at 4500 RPM for rapid acceleration profiles. Peak current capability reaches 160 A, enabling high dynamic response, while the holding brake operates at 24 VDC with 0.71 A consumption, engaging in 25 ms and releasing in 50 ms. The brake mass of 1.1 kg and overall motor weight of 34 kg reflect its heavy-duty construction. Liquid cooling ensures thermal stability under continuous operation, while the shaft seal prevents ingress of contaminants. Four 14 mm mounting holes on the flange simplify installation and alignment.

System integration is streamlined through compatibility with Rexroth Indramat drive controllers, allowing direct connection via standardized power and feedback connectors. The digital encoder output supports advanced control algorithms in PLC and CNC systems, enhancing synchronization in multi-axis setups. Target applications include packaging machinery, robotic arms, CNC machine tools, and automated assembly lines, where precision, reliability, and high torque density are paramount. Installation and maintenance should be performed by trained technicians following Bosch Rexroth Indramat guidelines.
