MSK101D-0450-FN-S1-AG2-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK101D-0450-FN-S1-AG2-NNNN servo motor from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor with a motor size of 101 and motor length of D. It delivers a continuous torque at standstill 100 K of 57.0 Nm and a maximum torque of 160.0 Nm at a maximum current of 187.7 A. Designed with liquid cooling and an A-Side power connector, it carries the Cooling FN constraint. The motor integrates optical encoder technology with a singleturn Hiperface interface offering 128 signal periods. An electrically-released holding brake provides 70 Nm torque, while the winding inductivity of 1,700 mH ensures dynamic response.

Frequently Asked Questions
Why is a 1,700 mH winding inductivity used in this servomotor?
The relatively high inductance smooths current ripple under PWM drive, reducing torque pulsation. It also provides filtering for drive voltage spikes in dynamic control loops.
Why is a singleturn optical encoder used instead of multiturn in this servomotor?
A singleturn encoder prioritizes simplicity, lower latency, and high reliability in applications with external absolute referencing. It avoids complexity and drift associated with multiturn gear mechanisms in compact servo axes.
What advantages does the 70 Nm holding brake bring in MSK101D-0450-FN-S1-AG2-NNNN servomotor?
The MSK101D-0450-FN-S1-AG2-NNNN servomotor brake secures the rotor during power-off or emergency stops, preventing unintended motion. It is electrically released, allowing smooth release when drive power returns without mechanical wear.
What is the function of the A-Side power connector in MSK101D-0450-FN-S1-AG2-NNNN servomotor?
The A-Side connector of MSK101D-0450-FN-S1-AG2-NNNN servomotor standardizes pinout for power, brake, and sensor signals in IndraDyn S systems. It ensures plug-and-play compatibility and simplifies wiring in modular multi-axis setups.
Why does the description require a “Cooling FN” constraint in this servomotor?
The “FN” denotes forced liquid cooling option in this motor, this constraint ensures correct coolant routing, sealing, and compatibility are respected in system integration.
