MSK101C-0300-FN-S2-AG0-RNNN
MSK IndraDyn S Synchronous Motors
MSK101C-0300-FN-S2-AG0-RNNN, manufactured by Bosch Rexroth Indramat, belongs to the MSK IndraDyn S Synchronous Motors series. This IndraDyn S Synchronous Servomotor features a compact Motor Size of 101 and carries the specific Winding Code of 0300 for high precision. Designed with a Plain shaft and specified as Without holding brake, it ensures a backlash-free, quiet operation under varied load conditions. The Increased concentricity design further reduces vibration and mechanical stress, extending the lifespan of the drive train.
The motor's thermal and power handling characteristics are optimized by Liquid cooling, efficiently dissipating heat during continuous operation. An integrated EnDat2.1 Encoder Interface with Optical Encoder Technology and Singleturn Encoder Turn Type delivers a resolution of 2048 signal periods per revolution for ultra-precise position feedback. A dedicated A-Side Power Connector streamlines installation and maintenance in high-density cabinet layouts. At 100 K, the unit can sustain a Continuous Current at Standstill of 21.3 A and deliver a Continuous Torque at Standstill of 36.5 Nm; under peak load it supports up to 84.2 A and generates a Maximum Torque of 110.0 Nm. Its low Winding Inductivity of 6,000 mH ensures fast current dynamics for rapid acceleration and deceleration.
Engineers leverage seamless integration with Bosch Rexroth IndraDrive control units to configure multi-axis motion sequences, ensuring synchronized operation across complex assemblies. The robust design and precision feedback enable reliable performance in demanding environments, from machine tools to robotics. This drive solution's combination of high torque density, precise encoder systems, and efficient liquid cooling makes it ideal for continuous start-stop processes and high-repetition-rate applications.

Frequently Asked Questions
What does “increased concentricity” change in MSK101C-0300-FN-S2-AG0-RNNN compared with standard rotor fits?
Its tighter rotor/stator concentricity lowers unbalance and air-gap variation for reducing radial force harmonics and bearing loads. It curbs mechanical vibration and acoustic emission to benefit contouring accuracy on precision axes.
Why is liquid cooling used on MSK101C-0300-FN-S2-AG0-RNNN, and what does it mean for continuous torque?
The liquid cooling evacuates winding and stator heat efficiently for preserving magnetic properties and keeping thermal drift low during continuous duty. It enables the quoted 100 K standstill ratings to be sustained in dense machines with repetitive cycles.
How does the EnDat 2.1 singleturn (2048 signal periods) in MSK101C-0300-FN-S2-AG0-RNNN improve positioning and diagnostics?
The EnDat 2.1 is a digital, bidirectional encoder interface that transmits precise position values and supports encoder data/diagnostic exchange over minimal lines. It reduces wiring complexity and enables early fault detection for stabilizing servo loops at higher bandwidths.
How does the A-side power connector benefit cabinet design for MSK101C-0300-FN-S2-AG0-RNNN?
Its fixed A-side orientation shortens cable runs and simplifies segregation from feedback lines for easing EMC routing rules. It also speeds service: power disconnect/replace tasks can be performed without disturbing encoder cabling.
What are the implications of “plain shaft” and “without holding brake” on MSK101C-0300-FN-S2-AG0-RNNN?
The plain shaft expects backlash-free couplings (e.g., bellows or elastomer) sized for the 110 Nm peak. Without a brake, the axis relies on drive-side holding torque or external mechanical locking for safe power-off conditions.
