MSK076C-0300-NN-S2-UP0-RNNN-R
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK076C-0300-NN-S2-UP0-RNNN-R from the MSK IndraDyn S Synchronous Motors series is a high-precision IndraDyn S Synchronous Servomotor designed for demanding automation tasks. This Product Type features a Motor Size 076 frame and a compact Motor Length C housing, optimized for installation in constrained spaces. The unit delivers smooth operation at a Rated Speed Code 0300 and benefits from an Increased concentricity design to enhance dynamic response. Its robust construction adheres to industrial standards and ensures consistent performance in continuous or intermittent duty cycles.
Featuring advanced feedback capabilities, the motor incorporates an Optical Encoder Technology with Encoder Turn Type Singleturn and an interface conforming to EnDat2.1 protocol. The Encoder Resolution of 2048 signal periods provides sub-micrometer position accuracy, while the Encoder Connector and Electrical Connection are both rotatable 240 degrees to simplify cabling and adaptability in the control cabinet. Designed for passive cooling via Natural convection, the motor operates without auxiliary fans, reducing maintenance requirements and acoustic emissions. The Shaft Type is a keyed design that ensures secure coupling, and the unit ships Without holding brake for applications where external braking solutions are preferred.
Additional features include Reduced shaft run-out, axial run-out according to DIN 42955 to minimize mechanical losses and vibration. The motor’s balanced rotor and rigid bearings contribute to extended service life under high acceleration profiles. With its combination of precise feedback, compact footprint, and streamlined thermal management, the MSK076C-0300-NN-S2-UP0-RNNN-R offers a reliable and efficient solution for robotics, packaging machines, and CNC applications.

Frequently Asked Questions
What integration advantages do the 240° rotatable power and encoder connectors provide during panel layout and machine wiring?
The swiveling connectors let engineers orient strain relief away from moving cable tracks to prevent torsion fatigue and eases cabinet routing. It also facilitate tight multi-axis layouts, standardized harnesses and faster field replacement without re-terminating conductors.
How does the optical singleturn EnDat 2.1 encoder with 2048 periods on MSK076C-0300-NN-S2-UP0-RNNN-R affect controllability and position granularity?
Its absolute singleturn feedback and fine grating enable precise commutation and tight servo gains for improving stiffness and minimizing following error. Its EnDat bidirectional digital link simplifies diagnostics and parameter storage while reducing analog noise paths and cabling complexity.
What mechanical benefits does the keyed shaft deliver, and when would you choose alternative couplings with this motor?
Its keyway ensures positive torque transmission and repeatable phasing for pulleys or rigid couplings for minimizing micro-slip. For precision servomechanics, select backlash-free, misalignment-tolerant elastomer or bellows couplings sized for inertia and permissible radial/axial loads.
What continuous and peak torque figures are typical for the MSK076C-0300 winding, and how do they guide axis sizing?
The MSK076C-0300 data show roughly 12 Nm continuous at 60 K, ~13.5 Nm at 100 K and about 43.5 Nm peak. Its values inform acceleration targets, gearbox selection and permissible load-inertia ratios during tuning.
What are the trade-offs of singleturn feedback on MSK076C-0300-NN-S2-UP0-RNNN-R versus multiturn variants in the MSK series?
The singleturn encoder give absolute position within one revolution but do not track revolution count for easing interface requirements. Its multiturn encoders add turn counting for enabling absolute homing for long-travel axes without external reference routines or battery-backed gear trains.
