MSK101C-0300-NN-S3-FG0-NPNN
MSK IndraDyn S Synchronous Motors
The MSK101C-0300-NN-S3-FG0-NPNN, manufactured by Bosch Rexroth Indramat, is part of the MSK IndraDyn S Synchronous Motors series. This high-performance IndraDyn S Synchronous Servomotor features a robust flange assembly (B5) design for direct mounting onto gearboxes or machine frames, delivering precision motion in a compact footprint. Its Plain shaft with standard keyway and compact Motor Size 101 profile streamlines mechanical coupling, while the integrated Terminal Box connector type allows straightforward power and feedback wiring. Passive Natural convection cooling eliminates the need for auxiliary fans or fluids, ensuring silent operation and minimal maintenance over long service intervals.
Operating at a Rated Speed Code 0300 (300 rpm nominal at standstill conditioning), the motor provides a continuous holding torque of 36.5 Nm under Continuous Current at Standstill 100 K of 21.3 A, ensuring secure positioning even when de-energized. Under dynamic conditions, it delivers up to 110.0 Nm Maximum Torque and tolerates currents up to 84.2 A Maximum Current for rapid acceleration and load changes. The onboard encoder utilizes Capacitive sensor technology in a Singleturn format, paired with a Hiperface interface to transmit 16 signal periods per revolution, enabling sub-micron resolution and deterministic feedback. A high Winding Inductivity of 6,000 mH smooths current transitions, reduces torque ripple, and improves low-speed stability in precision applications.
Engineered for seamless integration with Rexroth IndraDrive controllers and automation platforms, the MSK101C-0300-NN-S3-FG0-NPNN excels at synchronized multi-axis coordination and advanced motion profiles. Its maintenance-free cooling strategy and standardized connector layout greatly enhance system reliability, reducing downtime and lifecycle costs. Ideal for demanding environments such as CNC machine tools, packaging machinery, and robotic assembly lines, this motor guarantees reproducible performance and consistent throughput under continuous operation.

Frequently Asked Questions
How does passive natural-convection cooling on the MSK101C-0300-NN-S3-FG0-NPNN affect usable continuous torque and installation constraints?
Its natural convection relies on unobstructed airflow and clean surfaces, while contamination or enclosure crowding reduces heat dissipation and continuous rating. It is important to observe 0–40 °C ambient, IP65 conditions and provide thermal margins when sizing the axis.
What does a capacitive singleturn Hiperface encoder (16 signal periods) imply for control precision and tuning?
The S3 capacitive Hiperface system provides deterministic phase information and fine interpolated position for stable low-speed control and smooth commutation. It interprets 16 electrical periods per revolution for enabling accurate velocity loops and crisp contouring.
Why choose the plain keyed shaft and B5 flange on the MSK101C-0300-NN-S3-FG0-NPNN for gearbox coupling?
Its keyed plain shafts simplify torque transmission and service while the B5 flange centers the motor precisely on reducers or frames for minimizing misalignment. Its shaft/bearing force limits when selecting couplings and overhung loads.
How do 6,000 mH winding inductivity and 84.2 A maximum current influence drive selection and current ripple?
The higher inductivity damps di/dt and torque ripple, aiding low-speed smoothness but requiring adequate bus voltage and current-loop bandwidth for dynamics. It is important to ensure the selected IndraDrive current rating accommodates 84.2 A peaks during acceleration profiles.
What environmental ratings and basic limits apply, and how do they guide cabling via the terminal box?
The MSK101C tables indicate IP65 and 0–40 °C ambient; plan gland sizes, shielding and strain relief consistent with EMC practices in industrial environments. It is important to maintain clear airflow paths to preserve natural-convection performance.
