The Bosch Rexroth R911305112 (MHD112A-058-PG0-AN) is a synchronous servo motor engineered for precise drive applications. It utilizes digital servo feedback with an integrated multiturn encoder providing absolute position detection exceeding 4096 revolutions. The motor features a plain, sealed output shaft and operates without a holding brake. Technical parameters include an operating voltage of 380V, maximum peak current of 77A, four pole pairs, winding inductivity of 7.8 mH, and winding resistance of 0.86 Ohms at 20°C. The motor achieves a continuous standstill torque of 15.0 Nm, is constructed with class F insulation, and provides IP65 protection. Dimensions include a 130 mm centering diameter, 192 mm flange, and size 112 housing. Power connection is via side A output connector. The unit weighs 23 kg and is suitable for installation at altitudes up to 1000 meters above sea level. Liquid cooling is standard for this model.

Frequently Asked Questions

What is the benefit of absolute position detection over 4096 revolutions?

It provides precise multi-turn feedback without needing homing after power loss. This ensures immediate operational readiness in automated positioning systems.

Can the MHD112A-058-PG0-AN be mounted in any orientation?

While it supports flexible mounting, proper coolant flow and connector orientation must be maintained. Incorrect positioning can lead to heat retention or sealing issues.

Why is a sealed shaft important for servo motors in industrial environments?

A sealed shaft prevents ingress of dust, oil, and coolant, maintaining internal component integrity. It is especially beneficial in metalworking or food-processing applications.

What is the implication of using a plain shaft design on this motor?

A plain shaft allows for precise coupling with external gear or clutch systems. It requires accurate alignment during installation to avoid shaft stress.

Does the MHD112A-058-PG0-AN require an external brake system?

Yes, since it lacks an integrated holding brake, external braking or clamping devices may be needed. This is essential for vertical or safety-critical motion axes.
