MSK100A-0450-NN-S1-AG0-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0450-NN-S1-AG0-NNNN is part of the renowned MSK IndraDyn S Synchronous Motors series and represents a high-precision Product Type IndraDyn S Synchronous Servomotor engineered for demanding servo applications. This standard design motor features a compact Motor Size 100 frame combined with a Motor Length A profile, ensuring compatibility with a wide range of drive systems. Its robust Shaft Type Plain shaft construction delivers reliable torque transmission without the complexity of keyed or flanged variants. The absence of a Holding Brake Without holding brake further streamlines installation where dynamic braking or external brake modules are preferred.
The motor integrates cutting-edge feedback with an Encoder Technology Optical system and Encoder Turn Type Singleturn capability, interfacing seamlessly via a Encoder Interface Hiperface protocol. Fine position tracking is enabled by Encoder Resolution 128 signal periods, providing sub-micron accuracy in high-speed loops. The power stage connects through a dedicated Power Connector A-Side, reducing cabling errors and simplifying maintenance. Heat dissipation relies on Natural convection cooling, eliminating moving parts for silent operation and minimized upkeep. At a Rated Speed Code 0450, the unit offers a balanced compromise between velocity and torque, supported by a winding design with Winding Inductivity 7,800 mH for smooth current commutation.
Electrically, the motor sustains a Continuous Current at Standstill 100 K 13.6 A and delivers a Continuous Torque at Standstill 100 K 17.0 Nm for sustained holding tasks. For dynamic loads, its Maximum Current 54.0 A rating allows brief torque peaks up to Maximum Torque 54.0 Nm without derating. With its combination of optical feedback, high torque density, and maintenance-free cooling, the MSK100A-0450-NN-S1-AG0-NNNN is ideal for precision machine tools, robotics, and automated assembly lines where consistent performance and low lifecycle cost are essential.

Frequently Asked Questions
How does the S1 encoder on MSK100A-0450-NN-S1-AG0-NNNN aid precision, and what do 128 signal periods imply?
The optical single-turn Hiperface (S1) scale provides finely interpolated commutation and position data for enabling tight velocity and position loops. Its 128 signal periods support granular interpolation for reducing quantization error in machine-tool and robot axes.
Why choose natural-convection “NN” cooling on MSK100A-0450-NN-S1-AG0-NNNN, and when consider fan or liquid options?
Its natural convection eliminates fan wear, reduces acoustic emissions and simplifies maintenance. For elevated continuous torque or confined enclosures, surface-ventilated or liquid-cooled MSK variants lower thermal resistance to extend duty at speed without exceeding winding temperature limits.
What installation advantages come from the A-side power connector on MSK100A-0450-NN-S1-AG0-NNNN?
The A-side flange socket streamlines cable routing and strain relief on machines with left-hand cable channels for helping minimize bend radius violations. It also separates power from feedback paths predictably for aiding EMC practices and service accessibility.
Does the plain-shaft interface limit torque transfer on MSK100A-0450-NN-S1-AG0-NNNN compared to keyed hubs?
The precision cylindrical (plain) shaft works excellently with shrink-fit or clamp couplings for providing concentricity and low backlash. Its DIN keyway option can be specified, while torque capacity depends on hub geometry and locking method.
How do 13.6 A standstill current and ~7,800 mH inductance affect servo behavior on MSK100A-0450-NN-S1-AG0-NNNN?
The rated standstill current defines thermal headroom for holding torque and stiffness at zero speed. Its higher phase inductance attenuates current ripple for easing current-loop tuning and enabling smooth torque production under rapidly changing loads.
