The Bosch Rexroth synchronous servo motor, MPN R911292080 (MHD112B-035-NG0-BN), is equipped with a plain shaft and a B-side power connection. Designed with a winding code of 035, it achieves a maximum speed of 4000 RPM and a maximum continuous torque of 33 Nm at 100 K with natural cooling. The motor features a digital servo feedback encoder (HSF) for relative position detection, with a voltage constant of 108.5 V/1000min-1 and a winding inductivity of 5.5 mH. It weighs 34 kg, has a centering diameter of 130 mm, flange size of 192 mm, and a motor length classified as B. This model operates at a rated power of 10.1 kW and torque of 33.1 Nm under surface cooled conditions (60/100-K) and does not include a holding brake. Housing cooling is liquid-based. The motor is suitable for operation in ambient temperatures from 0 to 40°C and features a plain shaft with a shaft seal, as well as a thermal time constant between 20 and 40 minutes.

Frequently Asked Questions

Is the MHD112B-035-NG0-BN suitable for low-speed, high-torque applications?

Yes, its continuous torque of 28 Nm at standstill enables smooth motion at minimal speeds. It performs well in indexing tables, press drives, or conveyor positioning systems.

How does side B power connection affect installation layout?

It allows flexible cable routing when motors are mounted in parallel or confined spaces. This reduces electromagnetic interference risk and simplifies maintenance access.

What are the alignment considerations for its 130 mm centering diameter and 192 mm flange size?

Proper centering ensures vibration-free rotation and prevents bearing stress. These dimensions comply with common industrial mounting standards, easing mechanical interchangeability.

Why is a plain shaft with an integrated seal used instead of a keyed shaft?

The plain shaft design minimizes mechanical imbalance and vibration during high-speed operation. The shaft seal protects internal components from dust or coolant ingress, enhancing reliability.

Can the MHD112B-035-NG0-BN be integrated into existing automation systems easily?

Yes, it supports standardized power and signal interfaces, allowing straightforward replacement or integration. Its digital feedback and mechanical alignment features simplify commissioning and calibration.
