The Bosch Rexroth R911319505 (MHD112B-024-PP0-BN/S002) is a synchronous servo motor engineered with a keyed shaft, IP65 protective rating, and black-coated housing constructed from class F insulating materials. The motor supports a rated power output of 9.9 kW and a rated torque of 21.6 Nm at a rated frequency of 233 Hz. It features a maximum torque of 102 Nm, winding inductivity of 7.6 mH, and a moment of inertia of 192.0 x 10⁻⁴ kg·m². The stator windings are designed for rapid heat dissipation to the external walls. Operation parameters include an ambient temperature range of 0 to +40°C and a maximum installation elevation of 1000 meters. The unit has a liquid-cooled housing, digital servo feedback with absolute position detection (>4096 revolutions), a continuous standstill torque of 28.0 Nm, and a keyed shaft with a shaft seal. Additional mechanical dimensions include a centering diameter of 130 mm, a flange size of 192 mm, and a length code of 'B.' The power connection is oriented to side B via an output connector.

Frequently Asked Questions

How does the absolute position detection with 4096+ revolutions improve control precision?

It enables the motor to retain exact positional data even after power loss. This ensures repeatable accuracy in multi-axis CNC and robotic applications.

Can the MHD112B-024-PP0-BN/S002 be used in vertical axis applications?

It lacks a holding brake, so it’s not ideal for gravity-loaded vertical setups without an external braking system. Additional mechanical or servo-locking mechanisms are recommended.

How does motor size 112 influence compatibility with standard mounting interfaces?

This size corresponds to common flange and shaft dimensions in industrial servo systems. It simplifies retrofitting into existing Bosch Rexroth or third-party drive assemblies.

How does continuous torque of 28 Nm affect system performance?

It provides stable output for mid-to-heavy load motion tasks without overheating. This makes it suitable for sustained-duty machine axes or conveyor drives.

What maintenance factors are critical for long-term use of the MHD112B-024-PP0-BN/S002?

Regular checks of the cooling fluid circuit and shaft seal integrity are essential. Proper alignment and vibration monitoring prevent premature bearing wear and maintain efficiency.
