The R911287781 (MKD112B-058-GG1-AN) is a Rexroth Indramat AC servo motor featuring a 192 mm flange, motor size 112, and frame length B. It operates with a rated speed of 3000 rpm, provides a continuous standstill torque of 28.0 Nm, and achieves a rated torque of 30 Nm with a maximum torque output of 102 Nm. The unit is equipped with a plain shaft, shaft seal, and a 22 Nm electrically released holding brake. Feedback is supplied via a resolver (RSF) system, supporting relative position detection. The voltage constant is specified at 76 V/krpm and the torque constant is 0.77 Nm/A at 20°C. The motor is housed in an IP65 enclosure for protection against dust and water jets and supports operation within 0 to 45°C, with storage limits from -20 to 80°C. Rotor inertia measures 0.038 kgm² and the cooling method is radial. Connection is made via an output connector on the A-side.

Frequently Asked Questions

How does MKD112B-058-GG1-AN maintain safe stops on power-off events?

It includes a 22 Nm holding brake. The spring-applied mechanism locks the shaft when de-energized, preventing gravity-induced motion and preserving alignment on vertical lines during maintenance, e-stops, or planned shutdowns.

What continuous speed window frames throughput on MKD112B-058-GG1-AN?

It runs at a 3000 rpm rated speed. This operating point balances thermal rise with feed rate, enabling sustained traverses and predictable cycle times in packaging, robotics, and general assembly cells.

What electrical headroom informs protection and cabling on MKD112B-058-GG1-AN?

It allows 100 A maximum current. Drives, fusing, and conductors are sized to withstand short-term transients without nuisance trips, supporting aggressive motion commands while retaining thermal and safety margins.

Which datum ensures concentric mounting for MKD112B-058-GG1-AN?

It provides a 130 mm centering diameter. The pilot maintains co axiality with reducers, limiting vibration and extending coupling life during long duty cycles with reversing torque.

How does MKD112B-058-GG1-AN streamline cabinet layouts in multi-axis builds?

It uses Side A connection direction. This orientation simplifies routing within shared wireways, reduces bend stress, and improves service access when multiple axes terminate near common drive racks.
