MSK071C-0300-NN-S3-UG1-NNNN
MSK IndraDyn S Synchronous Motors
MSK071C-0300-NN-S3-UG1-NNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors offers a precision-engineered solution for high-performance motion control in industrial automation. This standard-design servomotor delivers responsive torque with a maximum of 44.0 Nm and smooth operation via a plain shaft format. The unit’s compact Motor Size 071 and optimized Motor Length C streamline integration into existing machinery, while the electrically released holding brake ensures secure stoppage under all conditions. Built to withstand harsh factory environments, it maintains consistent performance across varied application profiles.
Boasting advanced encoder features, the servomotor incorporates a rotatable Encoder Connector (240°) and Capacitive encoder technology to achieve a 16 signal periods resolution with a Singleturn turn type. Its Hiperface interface seamlessly feeds high-fidelity positional data to motion controllers. Thermal stability is maintained through natural convection cooling, eliminating the need for auxiliary fans and reducing maintenance. At rest, the motor sustains a Continuous Current at Standstill 100 K of 8.5 A and a Continuous Torque at Standstill 100 K of 14.0 Nm, while its peak capabilities extend to a Maximum Current of 32.9 A and a Maximum Torque of 44.0 Nm. The robust winding inductivity of 10,900 mH smooths current ripple, enhancing control accuracy and limiting electrical noise.
Engineers benefit from the servomotor’s plug-and-play compatibility with IndraDrive controllers and programmable motion platforms, enabling rapid system deployment. The unit’s reliable braking mechanism and high overload margin ensure uninterrupted operation in packaging, assembly, and robotics applications. With its precision feedback, compact footprint, and maintenance-free cooling, the MSK071C-0300-NN-S3-UG1-NNNN sets a benchmark for dependable, high-precision motion solutions.

Frequently Asked Questions
Why is the 10,900 mH winding inductivity of the MSK071C-0300-NN-S3-UG1-NNNN valuable to servo current loops?
The higher phase inductance attenuates PWM ripple for reducing dI/dt and electromagnetic emissions while smoothing torque at low speed. It increases current-loop stability margins, permitting higher effective switching frequencies without undue heating or acoustic artifacts.
How does the electrically released 23 Nm holding brake function on vertical axes or suspended loads?
The brake disengages for motion, on power loss or command. It clamps the shaft up to its rated torque to resist back-driving. This aids safe stops, fixture changes and maintenance positioning on Z-axes and gantries.
What do the 14.0 Nm / 8.5 A continuous-at-standstill and 44.0 Nm / 32.9 A peak ratings of the MSK071C-0300-NN-S3-UG1-NNNN mean for cycle design?
The sizing of holding/low-speed segments needs the use of continuous values, while reserve peak torque for short acceleration bursts within thermal limits. It is important to configure the drive’s torque limits and monitor temperature models to maintain margin during index-hold-return profiles.
How does the plain-shaft interface simplify coupling and gearbox selection on the MSK071C-0300-NN-S3-UG1-NNNN?
The cylindrical shaft accepts zero-backlash couplings and inline gearheads for reducing misalignment forces into the bearings. Its radial/axial loads against Rexroth shaft-load charts and bearing-life criteria needs to be confirmed to preserve service life and sealing integrity.
What advantages does the 240° rotatable encoder connector provide in tight cabinets or moving carriages?
It lets clocking the plug away from obstructions to ease bend radii and minimizing cable stress or EMI coupling. Its cleaner service loops improve compliance with wiring best practices and reduce enclosure depth requirements.
