MSK101D-0300-NN-M2-LG0-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK101D-0300-NN-M2-LG0-RNNN is a high-performance motor from the MSK IndraDyn S Synchronous Motors series designed for precise motion control in industrial automation. It features natural convection cooling for reliable heat dissipation, an optical encoder technology with multiturn absolute turn type, and a plain shaft for versatile mechanical interfacing. As an IndraDyn S Synchronous Servomotor, its primary function is to deliver smooth, accurate torque and speed regulation in demanding production environments.
This servomotor delivers robust performance with a continuous current at standstill (100 K) of 34.9 A and a continuous torque at standstill (100 K) of 57.0 Nm, ensuring stable holding capability when idle. The maximum current rating of 137.7 A and maximum torque of 160.0 Nm provide exceptional dynamic response and overload handling. With a winding inductivity of 3,200 mH, the MSK101D-0300-NN-M2-LG0-RNNN maintains smooth current flow and low electrical noise even under fluctuating loads. The EnDat2.1 encoder interface supports high-precision feedback, while an encoder resolution of 2048 signal periods ensures accurate position detection for closed-loop control.
Designed for ease of integration, the motor includes a left-side power connector and a plain shaft design that simplifies coupling with gearboxes and couplings. The increased concentricity construction enhances rotor stability, reducing vibration and extending bearing life. Supplied without a holding brake, this servomotor offers flexibility in system design and reduces maintenance points. Suitable for a wide range of industrial applications—from robotics to CNC machinery—the MSK101D-0300-NN-M2-LG0-RNNN delivers reliable performance, high efficiency, and long-term durability, helping to optimize productivity and reduce downtime in automated production lines.

Frequently Asked Questions
What is the significance of the winding inductance being 3,200 mH for system design?
A high inductance helps filter current ripples and reduce switching noise, but also slows the current change rate (dI/dt), which must be balanced by the drive’s current control bandwidth. In aggressive motion profiles, too much inductance can limit how fast torque can respond, so the drive must be tuned accordingly.
What is the thermal time constant and why is it important for duty cycle planning?
The thermal time constant is 100 minutes for this motor, meaning the motor requires that duration to reach ~63 % of final temperature under step power
How does the motor’s design facilitate coupling to gearboxes, and what coupling precautions should I take?
The plain (smooth) shaft allows flexible mounting via clamping sets, sleeves or keyed couplings, but you must ensure proper centering and torque transmission without introducing excessive axial or radial loads
What are the bearings’ expected lifetime under typical industrial radial/axial loads?
If operating within the specified radial and axial limits and maintaining mean speeds per the grease lifetime curves, the L10h bearing life is 30,000 h by ISO 281 standards
What resolution and accuracy trade-offs come from the EnDat 2.1 encoder with 2048 signal periods?
2048 signal periods (per revolution) in combination with multiturn capability gives precise absolute positioning with a resolution of about 2000 steps per rev. But mechanical backlash, cable length, and interpolation errors in the drive may still dominate real-world accuracy.
