MSK076C-0300-NN-M2-UP1-RNNN
MSK IndraDyn S Synchronous Motors
MSK076C-0300-NN-M2-UP1-RNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors series delivers precision motion control in a purpose-built, high-performance servomotor. This IndraDyn S Synchronous Servomotor combines compact design with advanced electromagnetic architecture to drive dynamic industrial applications. Engineered for resilience, it features an increased concentricity design that minimizes vibration and enhances long-term reliability. Its integrated shaft with keyway ensures positive torque transmission in demanding start–stop cycles.
The motor uses natural convection for maintenance-free thermal management, eliminating moving parts and reducing system complexity. Feedback is provided by an optical multiturn absolute encoder with a rotatable, 240° connector, delivering 2048 signal periods via the EnDat2.1 interface for sub-micrometer positioning accuracy. Rated for a continuous current at standstill 100 K of 8.1 A and a continuous torque at standstill 100 K of 13.5 Nm, it sustains peak demands up to a maximum current of 32.4 A and a maximum torque of 43.5 Nm. The holding brake, electrically-released applies 11 Nm of retention torque for instant load arrest, while a winding inductivity of 12 600 mH smooths current ripple and supports stable loop gains.
Seamless integration into Bosch Rexroth drive platforms is enabled by its standard rated speed code 0300, simplifying parameterization and reducing commissioning time. The motor’s robust construction and advanced encoder technology ensure high reliability in servo loops under continuous heavy loads. Ideal for pick-and-place systems, packaging machines, and CNC equipment, this servomotor maximizes throughput and uptime in precision automated processes.

Frequently Asked Questions
Why is the 11 Nm electrically-released holding brake advantageous for Z-axes in packaging or pick-and-place systems?
It clamps loads during power loss or servo disable to prevent drift and enables safe interventions. The 24 V coil (~0.71 A) releases quickly for supporting rapid cycles while maintaining retention capability.
How does 12,600 mH winding inductivity of MSK076C-0300-NN-M2-UP1-RNNN shape current ripple and crossover frequency in current controllers?
The high inductance attenuates PWM ripple for reducing torque pulsation and acoustic artifacts. It also expands stability margins to allow higher proportional gains before phase lag compromises loop bandwidth.
How does the increased concentricity mechanical design influence vibration spectra and bearing load in continuous start–stop duty?
Its reduced rotor runout cuts imbalance-driven harmonics to lower RMS vibration and fatigue stresses. Its result is steadier velocity at low speeds and improved bearing life under repetitive acceleration.
What are the implications of the 240° rotatable power/encoder connector in MSK076C-0300-NN-M2-UP1-RNNN for routing in compact machinery?
The selectable clocking angles enable cleaner cable exits and strain relief in tight panels. Its flexibility reduces EMI coupling risks and simplifies service access when re-terminating or swapping cables.
What torque/current margins should be considered between 13.5 Nm continuous and 43.5 Nm peak when sizing couplings and gear stages?
Its peak torque accommodates transient acceleration and disturbance rejection, not sustained duty. Its size mechanics for continuous thermal limits reserves peak for brief events within drive-configured time constants.
