The Bosch Rexroth R911286598 (MKD112D-027-KG3-BN) is a synchronous servo motor from the MKD series, designed for applications requiring high positioning accuracy and dynamic response. This model features a 192 mm flange, frame size 112, and a length type D, providing a continuous standstill torque of 48.0 Nm and rated torque of 28.5 Nm. It is equipped with a plain shaft, shaft seal, and a 70 Nm holding brake. The integrated resolver with multiturn absolute encoder allows position detection of over 4096 revolutions. The motor operates in S1 continuous mode, includes a side B output connector, and supports IM B5 flange mounting. Protection class is IP65 and the unit weighs 73 kg.

What is the engineering rationale for a 70 Nm holding brake relative to the 48 Nm continuous torque at standstill on MKD112D-027-KG3-BN for vertical axes?

The brake torque margin addresses static load, reflected inertia and safety factors so axes remain stationary under gravity and process disturbances. It improves emergency-stop holding capability and reduces drift when power is removed or the drive is disabled.

How do IP65 protection and a shaft seal with side-B connection benefit installations in packaging, printing, or food-adjacent environments?

The IP65 rating and a sealing ring limits dust and water ingress that protects bearings and feedback interfaces during washdown-adjacent or particulate-rich duty. Its side-B routing simplifies cable runs and helps maintain EMC, strain relief and service loops in tight machine frames.

How do the 130 mm centering diameter and 192 mm flange on MKD112D-027-KG3-BN influence coupling selection and permissible side loads?

The pilot (centering) bore locates the motor concentrically. It keeps belt/pulley radial forces within Rexroth recommendations for the MKD112 size class.

For printing and paper-processing, how does “absolute over 4096 revs” improve registration and uptime versus incremental-only encoders?

The multiturn absolute feedback allows immediate position availability after interruptions to limiting rethreading and print-mark alignment cycles. This speeds restart, reduces scrap and stabilizes synchronous sections in web handling.

What inertia-matching concerns exist given MKD112D-027-KG3-BN’s rotor inertia (~0.0138 kg·m²) and 73 kg mass for machine tools or gantries?

Its load-to-motor inertia ratio that preserves servo bandwidth while limiting resonance, it adds compliant couplings or notch filters as needed. Its base-frame stiffness and lifting/installation provisions for the motor’s mass.

Internal Product Review

The Rexroth Indramat’s MKD112D-027-KG3-BN motor comes with a plain-shaft design and connects to electrical main supply through its side-B connector. It has an integrated resolver feedback system with multiturn absolute detection of more than 4096 revolutions. Its 70-Nm brake and 48-Nm standstill torque makes it suitable for factory automation systems. This motor is constructed with IP65 rating and it tolerates temperature between 0 – 40 °C.
