MHD112D-024-NG2-RN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112D-024-NG2-RN is a precision MHD Synchronous Motors product designed for demanding servo applications. It features a robust Product Type of Servo Motor construction with a compact Motor Size of 112 and a smooth Plain shaft for direct coupling. With a Winding Code of 024 and integrated Digital servo feedback (HSF) encoder, this motor ensures accurate position control under dynamic loads. Its rugged design includes a Shaft Seal rated Yes, safeguarding internal components from contamination.
In performance terms, the MHD112D-024-NG2-RN delivers a Continuous Torque at Standstill of 48.0 Nm and a dedicated Holding Brake Torque of 32.0 Nm via a built-in Holding Brake to secure the axis when de-energized. The motor employs Liquid cooling housing to maintain optimal temperature under sustained load and prevent thermal overload. Electrical and encoder connections are both routed to the right through a standardized Power Connector interface, simplifying installation and service. Precise alignment is assured by a Centering diameter of 130 mm and a matching Flange size of 192 mm, accommodating industry-standard mounting.
Engineers will value the MHD112D-024-NG2-RN’s seamless integration with Bosch Rexroth IndraDrive controllers for advanced motion profiles and safety features. The combination of high torque density, reliable liquid cooling, and encoder-based Type of Position Detection (Relative) yields consistent performance in automation, handling, and packaging machinery. Overall, this servo motor offers long-term reliability and simplified maintenance through its professional design and quality construction.

Frequently Asked Questions
How do the 130 mm centering diameter and 192 mm flange of MHD112D-024-NG2-RN influence installation accuracy?
The centering spigot defines the datum for radial runout, while the standardized 192 mm flange maintains perpendicularity and bolt pattern repeatability. It reduces coupling misalignment and improves bearing life in direct-coupled axes.
When is the 32.0 Nm holding-brake torque on MHD112D-024-NG2-RN essential, and how should it be used?
It is recommended to use the brake to secure vertical or overhauling axes when the drive is disabled or in E-stop for preventing back-driving. It’s not a dynamic safety brake and apply motion-control-level holding only after axis standstill is confirmed.
How should the right-side power connector on MHD112D-024-NG2-RN be cabled for EMC and serviceability?
It routes shielded motor and feedback cables separately from mains and I/O for maintaining 360° shield terminations at drive plates, while Rexroth specifies RKL-line shielded motor cables for IndraDrive systems.
Does the MHD112D-024-NG2-RN require periodic bearing lubrication or encoder maintenance?
The MHD motors are designed as sealed, maintenance-free units with lifetime-lubricated bearings and integrated servo feedback. Its routine checks typically focus on cooling circuit integrity, connectors and vibration rather than scheduled relubrication.
How does liquid cooling improve duty cycle on the MHD112D-024-NG2-RN in continuous applications?
It increases heat rejection from the stator and housing for keeping winding temperatures within insulation limits during sustained load. It allows higher continuous torque utilization and stability under rapid start-stop profiles when correctly plumbed and bled.
