MSK100A-0300-NN-M2-BG0-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0300-NN-M2-BG0-RNNN from the MSK IndraDyn S Synchronous Motors series by Bosch Rexroth Indramat combines precision engineering with high dynamic performance. This IndraDyn S Synchronous Servomotor features a compact Motor Size 100 frame and Motor Length A, optimized for reduced inertia and rapid acceleration. Designed with natural convection cooling, the motor operates without auxiliary fans, simplifying cabinet layouts and lowering maintenance. A robust plain shaft and increased concentricity design ensure smooth torque delivery and minimal vibration across the full speed range.
The integrated optical encoder employs a multiturn absolute turn type with an EnDat2.1 interface, providing 2048 signal periods of resolution for precise position feedback. Power connections are handled through a dedicated B-Side power connector, streamlining installation in densely packed drive systems. At standstill and 100 K, the motor delivers 17.0 Nm continuous torque with a continuous current of 11.6 A, ensuring reliable holding capability. Under peak conditions it reaches a maximum torque of 54.0 Nm driven by a maximum current of 45.9 A, making it suitable for high-demand cyclic applications.
Internal winding inductivity of 11,200 mH yields smooth current profiles and low torque ripple, enhancing control accuracy. The absence of a holding brake reduces complexity while maintaining high torque density, ideal for synchronized multi-axis systems. Compact dimensions, advanced encoder technology, and rugged design make the MSK100A-0300-NN-M2-BG0-RNNN a versatile choice for servo-driven machine tools, robotics, and precision assembly lines.

Frequently Asked Questions
Why specify a plain shaft with increased concentricity on MSK100A-0300-NN-M2-BG0-RNNN, and how does that influence coupling and vibration?
The higher concentricity reduces runout-induced radial forces, improving bearing life and minimizing torque ripple at speed. It also widens coupling choices (elastomeric, bellows, disc) for enabling stiffer drivetrains without exciting misalignment-related resonances.
How should the 11,200 mH winding inductivity be interpreted for current ripple, torque linearity, and loop tuning?
The phase inductivity filters PWM current ripple for flattening torque production and easing compliance with tight velocity ripple specs. Its control-loop tuning can exploit higher L to push current-loop bandwidth without overshoot if drive voltage headroom covers di/dt demands.
What effective positioning resolution results from 2048 signal periods with common interpolation, and why does that matter?
Its typical digital interpolation (e.g., ×1024 to ×4096) yields ~2–8 million counts/rev (≈21–23 bits) for enabling fine contouring and low cogging velocity control. It high count density also improves low-speed stiffness and feed-forward linearization for precision axes.
How does the B-side power connector orientation on MSK100A-0300-NN-M2-BG0-RNNN simplify cable management in dense multi-axis machines?
The B-side routing lets power leads exit away from feedback cabling and tool interfaces for easing segregation and bend-radius compliance. It shortens trunk runs in gantries and cells for reducing voltage drop and cabinet congestion for neater, serviceable harnessing.
What integration considerations exist between MSK100A-0300-NN-M2-BG0-RNNN and Rexroth IndraDrive controllers (feedback, safety, networking)?
The IndraDrive controllers natively support EnDat encoders and multi-Ethernet fieldbuses for enabling deterministic motion. It integrates safety functions and coordinated control across packaging, automotive assembly and printing cells.
