The R911287204 (MHD115A-024-PP0-AA) is a Bosch Rexroth synchronous servo motor designated under frame size 115, length A, and a housing length of 370 mm. It incorporates a 192 mm flange with mounting holes and a 180 mm centering diameter. The motor shaft is keyed and equipped with a shaft seal. The unit features a digital servo feedback system with an integrated multiturn absolute encoder (>4096 revolutions), and the power connector is positioned on side A. The servo motor supports continuous torque at standstill of 32.0 Nm, a rated speed of 2000 RPM, and a maximum speed of 4000 RPM. Cooling is achieved through natural convection or forced air, with an operational ambient temperature range of 0 to 40 °C. The model does not include a holding brake but allows for the integration of a 70 Nm brake. The unit weighs approximately 30 kg and uses winding code 024.

Frequently Asked Questions

How does the frame shape support installation stability?

The rectangular frame design distributes structural stress evenly across the mounting surface. The consistent geometry ensures vibration control and secure alignment with precision couplings during operation.

Why is the motor housing ribbed externally?

The ribbed exterior increases the surface area for natural convection cooling. The uniform heat dispersion reduces thermal concentration and maintains operational consistency under variable duty cycles.

How does the shaft design enhance mechanical integration?

The precision-ground shaft features a standardized keyway for torque transmission alignment. The balanced construction minimizes axial runout and ensures reliable coupling with gears or pulleys.

What impact does connector placement have on assembly design?

The axial connector configuration allows efficient cable routing within compact enclosures. The optimized placement simplifies system wiring and improves accessibility for maintenance or sensor replacement.

How do mounting flange dimensions aid compatibility?

The standardized flange dimensions follow IEC and DIN mechanical interface norms. The consistent sizing allows interchangeable installation across automation systems with minimal mechanical adaptation.
