The Bosch Rexroth MPN R911298425 (MHD112B-035-NP0-AN) is a synchronous servo motor configured with a keyed output shaft and integrated shaft seal. It utilizes digital servo feedback (HSF) for position detection and supports liquid cooling. The motor produces a theoretical maximum torque of 102 Nm at 4000 RPM and maintains a continuous torque of 42 Nm at 39 A during surface cooling. The unit has a 192 x 10⁻⁴ kg·m² moment of inertia and a thermal time constant between 20 and 40 minutes. Rated speed under natural cooling at 100 K is 2500 RPM with a frequency of 167 Hz. This motor has a flange size of 192 mm, a centering diameter of 130 mm, a B-length housing, and the power connection is oriented to side A via an output connector. The winding code is 035 and the version does not include a holding brake.

Frequently Asked Questions

Why is a digital servo encoder with relative feedback suitable for automation systems?

Relative feedback offers fine motion control and smooth response for high-speed positioning. It’s ideal for applications requiring repeatable accuracy but not absolute position memory after power loss.

What effect does the 28.0 Nm continuous torque at standstill have on system design?

It enables stable holding and low-speed operations without overheating. Designers can use smaller gear ratios while maintaining smooth control under static loads.

How should the MHD112B-035-NP0-AN be positioned for optimal power connection to side A?

The motor housing should be oriented to allow unobstructed cable routing from side A. Proper strain relief prevents connector fatigue and ensures long-term reliability in motion systems.

What are the advantages of using liquid-cooled servo motors in CNC and packaging machinery?

They allow compact motor mounting with high thermal efficiency, ideal for tight enclosures. The cooling system helps sustain precision during prolonged, repetitive motion cycles.

How does the winding code 035 influence motor selection?

The winding code defines torque-speed characteristics and compatibility with specific drive controllers. Choosing the correct code ensures optimal current utilization and response.
