MSK100A-0300-NN-M2-LG0-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0300-NN-M2-LG0-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor engineered for precision motion control. It features Natural convection cooling and a Left-Side power connector for streamlined cabinet layouts. The motor incorporates Optical encoder technology with a Multiturn Absolute turn type, an EnDat2.1 interface, and 2048 signal periods resolution for exceptional position feedback. Its Motor Size 100 frame and Motor Length A designation ensure compatibility across standardized mounting patterns.
With a Continuous Current at Standstill 100 K of 11.6 A and a Continuous Torque at Standstill 100 K of 17.0 Nm, this servomotor delivers reliable holding performance under static loads. Peak demands are met by a Maximum Current rating of 45.9 A and a Maximum Torque capacity of 54.0 Nm, facilitating rapid acceleration and deceleration. The Winding Inductivity of 11,200 mH supports smooth current transitions and contributes to low electrical noise. Designed with Increased concentricity and a Plain shaft configuration, the motor achieves balanced rotation and simplifies coupling.
Maintenance requirements are minimized thanks to the omission of a holding brake (Without holding brake) and the inherent reliability of the natural convection system. The robust optical encoder and high-resolution feedback pave the way for closed-loop control with minimal drift. With its optimized form factor, the MSK100A-0300-NN-M2-LG0-RNNN is ideally suited for packaging machines, CNC equipment, and robotic applications where precise torque delivery and compact installation are critical.

Frequently Asked Questions
How does the 11,200 mH winding inductance influence current ripple and EMC behavior in the MSK100A family?
The inductance moderates di/dt for reducing current ripple into the inverter and smoothing torque production. It helps with conducted emissions and allows current controllers to run stable with modest switching frequencies and typical cable lengths.
What benefits come from the “increased concentricity” and plain-shaft configuration on MSK100A-0300-NN-M2-LG0-RNNN?
The tighter rotor/runout tolerances minimize radial vibration for easing alignment with bellows or clamp couplings. Its plain shaft broadens coupling choices and simplifies assembly when backlash and compliance must be tightly controlled in precision axes.
How do the 17.0 Nm continuous @ 100 K and 54.0 Nm max torque ratings on MSK100A-0300-NN-M2-LG0-RNNN translate to motion profiles?
The continuous torque sets sustained feed forces without exceeding thermal limits, while 54 Nm accommodates bursts for acceleration, cornering or tool approach. Its drive parameterization should constrain duty cycles to avoid cumulative heating beyond the 100 K benchmark.
How does the left-side (LG0) power connector orientation on MSK100A-0300-NN-M2-LG0-RNNN aid cabinet and machine layout?
Its routing aligns cable exits with left-hand raceways in many gantries for reducing bend radii and strain at the motor head. It also helps segregate power from feedback harnesses to improve EMC margins.
Why choose natural-convection cooling on MSK100A-0300-NN-M2-LG0-RNNN for machine enclosures with acoustic limits?
The convection eliminates fans for reducing acoustic emissions and particulate ingress paths while simplifying maintenance. Its thermal design still supports significant continuous torque when paired with proper mounting surfaces and ambient derating in sealed cabinets.
