MSK076C-0450-NN-S1-UG0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK076C-0450-NN-S1-UG0-NNNN from the MSK IndraDyn S Synchronous Motors series is a high-precision Product Type designed for demanding servo applications. This Standard design features a Motor Size 076 frame with a Motor Length C configuration and a Rated Speed Code 0450, delivering consistent performance in a compact package. The unit comes Without holding brake and is equipped with a Plain shaft for straightforward mechanical integration. Natural convection Cooling ensures silent operation while maintaining thermal stability under varying loads.
The motor’s electrical characteristics are tailored for resilience and precision. At 100 K standstill, it provides a Continuous Current of 13.7 A and a Continuous Torque of 13.5 Nm, with a Maximum Current of 54.9 A and a Maximum Torque of 43.5 Nm available for peak demands. A Winding Inductivity of 4,700 mH contributes to smooth current transitions and reduced electromagnetic noise. Positional feedback is handled by an Optical Encoder using a Singleturn Turn Type, featuring 128 signal periods for high resolution. The encoder’s Hiperface Interface and a Rotatable, 240° Encoder Connector allow flexible mounting and precise synchronization with drive electronics.
Built to integrate seamlessly into automated systems, this synchronous servomotor leverages its robust construction and advanced encoder interface for reliable field operation. The absence of a holding brake simplifies maintenance and minimizes downtime, while the plain shaft design accommodates a wide range of couplings. Whether applied in robotics, packaging, or precision machine tools, the MSK076C-0450-NN-S1-UG0-NNNN delivers dependable performance with minimal footprint and exceptional control fidelity.

Frequently Asked Questions
How does the singleturn optical Hiperface (128 periods) on MSK076C-0450-NN-S1-UG0-NNNN affect control precision and commissioning?
The Sin/Cos Hiperface interface with 128 signal periods enables fine interpolation in the drive for improving commutation accuracy and low-speed smoothness. Its 240° rotatable encoder connector also eases cable routing and strain-relief during installation.
Why does the MSK076C-0450-NN-S1-UG0-NNNN specify natural-convection cooling, and how does that relate to its 100 K continuous ratings?
Its natural-convection cooling simplifies integration and lowers acoustic emissions. Its 13.5 Nm / 13.7 A at 100 K reflects thermal equilibrium under that cooling mode. It is also important to ensure enclosure airflow and mounting clearances.
What dynamic headroom do the 43.5 Nm / 54.9 A maxima provide on MSK076C-0450-NN-S1-UG0-NNNN?
These peak values permit short-duration torque surges for rapid indexing, settling or overcoming static friction without upsizing the motor. Its drive should enforce time-at-peak and thermal models to protect insulation and bearings.
Which couplings suit the plain shaft, and what misalignment tolerances should be considered?
The use of backlash-controlled elastomeric or disc couplings or keyless locking hubs is sized for the peak torque and shaft fit. Its angular/parallel misalignment capacity minimize bearing load and maintain servo bandwidth.
How does the ~4.7 mH winding inductance on MSK076C-0450-NN-S1-UG0-NNNN influence current ripple and EMC?
The moderate inductance attenuates PWM ripple to ease current loop tuning and reduce conducted emissions. It also defines the electrical time constant with phase resistance. Matching drive switching frequency and current loop gains to L/R is recommended.
