The R911287224 (MHD112D-027-NP0-LN) is a Bosch Rexroth MHD series servo motor engineered for rapid-response automation tasks. It utilizes permanent magnet materials and features a low inertia mass for optimal torque-to-inertia performance, supporting high dynamic applications. Key mechanical attributes include a flange size of 192 mm, centering diameter of 130 mm, and a keyed shaft with shaft seal. The housing is liquid-cooled and offers IP65 ingress protection. The motor supports a maximum speed of 3,000 rpm with a continuous standstill torque of 48.0 Nm and a theoretical maximum torque of 187.0 Nm. The unit employs digital servo feedback (HSF) for relative position detection, has a winding code of 027, and is configured without a holding brake. The power connector is oriented to the left. Operating parameters include a maximum ambient temperature of 40°C and installation altitude up to 1,000 m.

Frequently Asked Questions

Which flange and centering dimensions does it use?

The flange size is 192 mm with a centering diameter of 130 mm. The dimensions enable standard mounting interfaces and compatibility with typical machine housings.

What is the bearing arrangement for radial loads?

The motor uses maintenance-free bearings designed for high radial load capacity. The feature supports overhung mounting of pulleys or pinions without compromising alignment.

How does rotor inertia influence responsive motion?

The motor has low rotor inertia to enable rapid acceleration and deceleration. The reduced inertia improves dynamic response while requiring careful drive tuning for stability.

What shaft design does the motor include for coupling?

The motor uses a keyed shaft with sealing to resist contamination. The keyed interface simplifies torque transfer to gearboxes or couplings while preserving environmental sealing.

How does the IP65 enclosure affect form factor?

The IP65-rated housing uses sealed covers and robust joints to prevent dust and water ingress. The design ensures protection without adding excessive bulk or interfering with airflow.
