MSK076C-0300-NN-S2-UP0-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK076C-0300-NN-S2-UP0-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor engineered for precision drive systems. This Product Type features a Motor Size 076 frame and a compact Motor Length C housing, designated by the Rated Speed Code 0300, ensuring consistent integration into standardized machine platforms. Its Design: Increased concentricity guarantees minimal runout and superior dynamic balance, while the Shaft Type: Shaft with keyway provides secure coupling for high-torque applications. The motor is supplied Without holding brake, reducing complexity where braking is managed externally.
Encoder and feedback integration is handled by an Encoder Technology: Optical singleturn unit, offering Encoder Resolution: 2048 signal periods for high-accuracy positioning. The Encoder Interface: EnDat2.1 ensures robust digital communication, and the Encoder Connector: Rotatable, 240° design simplifies installation in confined cabinet spaces. This configuration lays the foundation for repeatable, high-speed control loops in both servo and motion-control environments.
Performance is outstanding: at Continuous Current at Standstill 100 K: 8.1 A, the motor delivers a Continuous Torque at Standstill 100 K: 13.5 Nm, enabling precise holding capacity without thermal overload. Peak demands up to Maximum Current: 32.4 A are met with a Maximum Torque: 43.5 Nm output, giving ample dynamic reserve for acceleration and deceleration phases. The large Winding Inductivity: 12,600 mH smooths current transitions, improving drive stability under rapid load changes. Natural convection Cooling maintains safe winding temperatures during sustained operation, and the overall design supports predictable performance across industrial temperature ranges.

Frequently Asked Questions
How does the optical singleturn (2048 periods) encoder with EnDat 2.1 enhance positioning accuracy on MSK076C-0300-NN-S2-UP0-RNNN?
It delivers fine interpolated position data and stable digital transmission for reducing analog noise paths. Its EnDat enables parameter readout and diagnostics for tighter servo loops and rapid commissioning in digital drive systems.
Why does the “increased concentricity” design matter for this motor’s mechanics?
Its improved concentricity reduces shaft runout and unbalance for lowering vibration, bearing loads and velocity ripple. It translates into better contour accuracy and smoother current/torque utilization in high-bandwidth motion loops.
How does natural-convection cooling on MSK076C-0300-NN-S2-UP0-RNNN affect duty and scaling?
It’s ideal when continuous losses are moderate and airflow is available around the frame. The MSK family also supports retrofit blower or liquid cooling options when higher continuous power density is required.
What advantage does the shaft with keyway offer for MSK076C-0300-NN-S2-UP0-RNNN couplings?
The keyed interface provides positive drive and repeatable torque transmission for minimizing micro-slip under dynamic reversals. It simplifies hub selection for timing pulleys, gearheads or bellows couplings in cyclic axes.
What role does the 12,600 mH winding inductivity play in control stability?
The higher phase inductivity attenuates current ripple and shapes the electrical time constant for easing current-loop tuning. It supports smoother torque transitions during step loads and reduces amplification of bus ripple into mechanical motion.
