MSK076C-0300-NN-S1-UP1-NNNN
MSK IndraDyn S Synchronous Motors
MSK076C-0300-NN-S1-UP1-NNNN, manufactured by Bosch Rexroth Indramat, is a high-performance member of the MSK IndraDyn S Synchronous Motors series. The Product Type features a robust Design with a compact Motor Size 076 and a versatile Motor Length C, optimizing it for space-constrained installations. An integrated Holding Brake offers immediate locking, while Natural convection Cooling ensures maintenance-free operation without external fans. Its standard-shaft configuration and electrically released brake provide broad compatibility across automation platforms.
Equipped with an optical Encoder Technology and rotatable Encoder Connector 240° interface, the motor delivers high-resolution feedback via the Hiperface Encoder Interface supporting 128 signal periods per revolution. It generates 13.5 Nm continuous torque at standstill (100 K) under 8.1 A continuous current, while sustaining peaks up to 43.5 Nm maximum torque and 32.4 A maximum current for dynamic acceleration. A substantial 12,600 mH winding inductivity smooths current ripple and enhances low-speed stability, and the keyed shaft ensures secure coupling to downstream loads. The Rated Speed Code 0300 further aligns motor performance with precise velocity and positioning requirements.
Designed for seamless integration, the MSK076C-0300-NN-S1-UP1-NNNN pairs effortlessly with standard servo drives and industry PLCs via its standardized encoder interface and brake control terminals. Its rugged construction and fanless cooling scheme deliver exceptional reliability in continuous-duty applications, reducing downtime and service costs. Ideal for machine tools, robotics, and packaging equipment, this motor excels where precise torque control and compact form factor are essential.

Frequently Asked Questions
Why is the 12,600 mH winding inductivity valuable on MSK076C-0300-NN-S1-UP1-NNNN for low-speed operation?
The higher inductivity attenuates PWM ripple for smoothing phase current and reducing torque ripple. It also broadens current-loop stability margins to aid precise creep moves and contouring under high inertia loads.
How does the singleturn optical Hiperface encoder in MSK076C-0300-NN-S1-UP1-NNNN enhance commutation and position fidelity?
The hybrid Hiperface scheme combines analog sine/cosine tracks with a digital RS-485 channel for enabling fine interpolation and parameter readout. Its architecture reduces quantization noise and preserves phase accuracy at low speeds.
How does the electrically-released 11 Nm holding brake on MSK076C-0300-NN-S1-UP1-NNNN support vertical axes?
The brake engages when de-energized to lock the shaft for preventing unintended motion during power loss. An electrical release signal frees the rotor to enable controlled homing and gravity-axis hold.
How does the 240° rotatable power/feedback connector on MSK076C-0300-NN-S1-UP1-NNNN aid tight machine builds?
Its adjustable orientation eases cable routing to meet bend-radius constraints and minimize strain near moving carriages. It also helps segregate motor and feedback paths to manage EMC coupling.
What coupling guidance applies to the keyed shaft on MSK076C-0300-NN-S1-UP1-NNNN in backlash-critical drives?
The keyway prevents hub slip under transient torque; use zero-backlash couplings and fit tolerances per ISO H7/k6. It is important to verify permissible radial/axial loads against the Rexroth shaft-load charts before sizing.
