The MPN R911307688 (MHD112A-035-NP0-AN) is a Bosch Rexroth MHD series servo motor designed for applications requiring precise speed and position control. It features a high operational reliability with low inertia and utilizes a digital servo feedback (HSF) system for relative position detection. The motor supports both natural convection and surface cooling, with liquid cooling implemented in the housing. Key technical specifications include a continuous standstill torque of 15.0 Nm, motor length A, centering diameter of 130 mm, and flange size of 192 mm. The keyed shaft, compliant with DIN 3760 - design A and DIN 6885-1, is equipped with a shaft seal. The servo motor has a power output connector oriented to side A and does not include a holding brake. Its IP65 ingress protection rating ensures resistance to dust and water sprays. Powered by winding code 035, the motor maintains peak torque over a wide speed range using electronic commutation.

Frequently Asked Questions

How does the keyed shaft design improve torque transmission?

The keyed interface provides positive mechanical engagement between the motor and driven component. This minimizes slippage and ensures precise torque transfer in dynamic industrial applications.

What role does the digital servo feedback encoder play in system accuracy?

It delivers high-resolution position and speed data directly to the controller. This feedback loop allows precise synchronization essential in CNC, robotics, and pick-and-place machinery.

Why is liquid-cooled housing advantageous over air-cooled alternatives?

Liquid cooling allows higher power density in compact installations. It is especially effective in enclosed or high-temperature environments where air cooling is insufficient.

What are the benefits of the “A” motor length configuration in the MHD112A-035-NP0-AN?

This shorter length supports tight-space integration without reducing torque capability. It suits multi-axis or modular automation setups with limited machine footprint.

How does the relative position detection system influence performance?

It measures incremental motion, enabling smooth velocity control and repeatable positioning. This makes it ideal for coordinated motion in conveyor, packaging, and tool-handling systems.
