The R911276790 (MKD112B-058-KG1-BN) is a Rexroth MKD synchronous servo motor with a motor size of 112, length B, and flange dimension of 192 mm. It features a plain shaft with shaft seal, resolver feedback for absolute position detection (>4096 revolutions), and a holding brake providing 22 Nm braking torque. Designed for continuous operation in demanding environments, this motor achieves 28.0 Nm continuous standstill torque and utilizes electronic commutation for stable torque across a broad speed range. Additional properties include 302 V winding code 058, moment of inertia 0.0059 kg·m², vibration class R, and side B connection direction, operating from 0–40 °C ambient and –20 to +80 °C storage temperatures.

How does absolute feedback change restart behavior on MKD112B-058-KG1-BN?

The motor’s encoder secures position data across more than 4096 revolutions. Even after shutdown, axes restart instantly without homing, preserving coordinated moves and saving valuable minutes during resets or scheduled maintenance.

Why does the brake matter for vertical axes on MKD112B-058-KG1-BN?

The built-in 22 Nm holding brake prevents shafts from slipping when power is off. This spring-applied system secures vertical loads, avoids drift, and maintains precise positioning during outages or controlled halts.

Why is rotor behavior easy to tune on MKD112B-058-KG1-BN?

Its 0.0059 kgm² inertia enables brisk acceleration and fast stabilization. Low inertia allows higher loop gains, sharp motion transitions, and repeatable indexing moves without introducing overshoot across challenging applications and cycles.

What mechanical datum protects alignment on MKD112B-058-KG1-BN?

The 130 mm centering diameter ensures coaxial mounting. Attachments align concentrically, reducing vibration and extending component life. This secure mechanical reference maintains efficiency while protecting bearings and couplings at higher speeds.

How does environment planning factor in for MKD112B-058-KG1-BN?

It runs within 0–40 °C ambient and stores between −20 and +80 °C. Following these limits protects insulation, seals, and overall motor integrity through seasonal changes or varied installation conditions.
