MSK101C-0450-NN-M1-BG2-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK101C-0450-NN-M1-BG2-NNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor designed for precision motion control. This Product Type features a compact Motor Size 101 frame with a Motor Length C configuration and a Rated Speed Code 0450, delivering consistent speed stability. Built to the Standard Design specification, it integrates seamlessly into automated systems and supports a Plain shaft interface for direct coupling. Crafted under the stringent quality standards of Bosch Rexroth Indramat, this servomotor meets demanding industrial requirements while maintaining a user-friendly footprint.
Cooling and environmental resilience are assured with Natural convection technology, although the unit Requires Cooling FN for extended high-power operation. The motor’s Holding brake is electrically released and rated at 70 Nm of Holding Brake Torque to secure loads instantly on power loss. Power delivery is handled through the robust B-Side Power Connector, ensuring fail-safe current supply under dynamic load changes. Precision position feedback comes from Optical Encoder Technology with a Multiturn Absolute Encoder Turn Type, featuring the high-speed Hiperface Encoder Interface and 128 signal periods for fine resolution. The stator’s Winding Inductivity of 3,300 mH supports smooth current transitions and minimizes torque ripple.
At standstill and 100 K, the motor sustains a Continuous Current of 28.6 A and produces a Continuous Torque of 36.5 Nm, enabling reliable holding capacity under thermal stress. Peak performance delivers a Maximum Current of 113.0 A and a Maximum Torque of 110.0 Nm, ensuring powerful acceleration and dynamic load response. Together, these specifications make the MSK101C-0450-NN-M1-BG2-NNNN an optimal choice for precision robotics, packaging machinery, and servo-driven production lines.

Frequently Asked Questions
How does the 3.3 mH winding inductivity in MSK101C-0450-NN-M1-BG2-NNNN influence current slew rates and torque ripple?
ts higher inductivity smooths phase-current transitions for reducing ripple and cogging-induced speed modulation under tight velocity loops. It benefits precision contouring and servo stiffness in multi-axis machines operating at variable loads.
What continuous-duty capability is available at 100 K, and when is “Cooling FN” advisable on MSK101C-0450-NN-M1-BG2-NNNN?
It delivers 36.5 Nm with 28.6 A that is suitable for moderate thermal loading and intermittent cycles. It is important to add forced-ventilation (FN) blowers where sustained torque density is required to avoid thermal limiting and increase continuous output.
What dynamic headroom do 113 A (Imax) and 110 Nm (Mmax) give MSK101C-0450-NN-M1-BG2-NNNN?
The high peak current/torque margins support fast acceleration and transient load rejection without saturating the drive. It combined with the rotor inertia listed for 101C frames yields responsive yet controllable axis behavior.
Why specify a Hiperface multiturn optical encoder (128 signal periods) on this motor?
The Hiperface multiturn encoders provide absolute position over multiple revolutions and fine sine/cosine interpolation from 128 periods per rev for enabling accurate commutation and low-jitter speed control. It simplifies homing and improves restart reliability after e-stops.
What bearing lifetime should users expect under prescribed load limits?
The IndraDyn S motors are calculated for an L10h bearing life of ~30,000 operating hours when radial/axial loads remain within catalog limits. Its proper coupling alignment and load modeling are essential to achieve this figure.
