The R911278513 (MHD112B-058-NG0-BN) is a synchronous servo motor from the MHD series by Bosch Rexroth, designed for use with digital drive controllers in automation applications. It features size 112 in length B with a 130 mm centering diameter and 192 mm flange size. The motor supports surface and natural convection cooling, operates with a maximum speed of 4000 min-1, and delivers a continuous standstill torque of 28.0 Nm. It is equipped with digital servo feedback (HSF) for relative position detection, has a plain shaft with shaft sealing ring, an output-side power connector oriented to side B, and is supplied without a holding brake. The device weighs 34 kg (without blower) and requires all operation and servicing to be performed by qualified personnel with a minimum 10-minute discharge time after shutdown. Underwater operation is not permitted.

Frequently Asked Questions

What thermal solution supports continuous operation in high-duty applications?

Its liquid-cooled housing enables stable thermal performance under constant load. This prevents heat buildup and supports reliable long-cycle operation.

How is shaft protection maintained in contaminated or open-frame machine setups?

The plain shaft is equipped with a shaft seal to block fluid and particle ingress. This increases durability in dust-prone or semi-exposed environments.

Is this model capable of sustained torque output during static hold phases?

It delivers 28.0 Nm of continuous torque at standstill. This supports precision holding in zero-speed indexing or dwell-intensive applications.

What type of encoder feedback does the MHD112B-058-NG0-BN provide for motion tracking?

It uses a digital HSF encoder offering relative feedback. This requires homing at startup to re-establish positional reference.

Can the motor be mounted directly into standard industrial servo frames?

With a 130 mm centering diameter and 192 mm flange, it matches common mounting patterns. This allows seamless integration into modular machine designs.
