MSK100A-0450-NN-M1-BG1-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0450-NN-M1-BG1-NNNN from the MSK IndraDyn S Synchronous Motors series is a IndraDyn S Synchronous Servomotor engineered for precision motion control in medium-duty automation systems. Built on a robust standard design, it features a motor size 100 frame and a compact motor length A that optimize cabinet real estate. Cooling is achieved through natural convection, eliminating the need for integrated fans and reducing maintenance points, while the power connector on the B-Side simplifies cable routing in confined installations. The servo’s feedback section employs optical encoder technology with a multiturn absolute turn type, a high-speed Hiperface interface, and 128 signal periods resolution, ensuring micrometer-scale positioning accuracy.
Performance at rest and under load is handled with ease: the MSK100A carries a continuous current at standstill 100 K of 13.6 A and generates a continuous torque at standstill 100 K of 17.0 Nm, providing reliable holding power. When motion demands spike, it supports a maximum current of 54.0 A and delivers up to a maximum torque of 54.0 Nm, enabling rapid acceleration and high dynamic response. The integrated holding brake, electrically-released for controlled activation, supplies a holding brake torque of 32 Nm to secure loads instantly upon power loss. A rugged plain shaft design ensures backlash-free coupling to gearboxes or load interfaces, and the winding inductivity of 7,800 mH contributes to smooth current transitions and fine-tuned torque control.
As a precision drive component, the MSK100A-0450-NN-M1-BG1-NNNN integrates seamlessly into existing MSK automation frameworks, sharing mounting dimensions and parameter profiles for rapid commissioning. Bosch Rexroth Indramat’s rigorous quality validation underpins every motor, from material selection to end-of-line testing, guaranteeing consistent performance across production batches. This servo motor’s blend of high torque density, advanced encoder feedback, and low-maintenance convection cooling makes it an ideal choice for packaging machinery, gantry systems, and other industrial applications demanding repeatable positioning and robust load holding.

Frequently Asked Questions
How does the M1 optical multiturn Hiperface encoder with 128 signal periods on MSK100A-0450-NN-M1-BG1-NNNN affect absolute accuracy and repeatability in micro-positioning tasks?
It provides absolute angle and turn count, avoiding homing and cycle-to-cycle drift. Its 128 periods and drive interpolation achieves fine quantization and stable repeatability for tight movements.
Why is the plain-shaft option on MSK100A-0450-NN-M1-BG1-NNNN preferred for precise gearbox coupling and backlash control?
The cylindrical shaft supports shrink-disc or clamp-hub couplings with concentric fit and minimal micro-play. It improves torsional stiffness and repeatability on reversing axes and precision linear stages.
How do the 13.6 A standstill current and 17.0 Nm continuous standstill torque translate to holding capability and thermal margins in static load cases?
The 100 K standstill point defines sustainable electromagnetic holding without overshoot. Its correct current limiting preserves insulation life while leaving headroom for short transients.
What functional role does the 32 Nm electrically-released holding brake play during emergency stop or power-loss events?
The MSK100A-0450-NN-M1-BG1-NNNN has spring-applied brake that engages automatically when power drops, locking the axis. Its 32 Nm secures vertical or inclined loads until controlled recovery.
How does the listed winding inductivity of 7,800 mH influence current ripple and torque smoothness under PWM drive control?
The MSK100A-0450-NN-M1-BG1-NNNN's higher phase inductance filters switching ripple for smoother torque at a given carrier frequency. It constrains current-loop bandwidth, so tuning must balance responsiveness and noise rejection.
