MSK100A-0300-NN-S1-BP1-NNNN
MSK IndraDyn S Synchronous Motors
The MSK100A-0300-NN-S1-BP1-NNNN synchronous servomotor by Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series, engineered to deliver precise motion control in industrial automation applications. With a high Winding Inductivity of 11,200 mH and a Maximum Current rating of 45.9 A, this motor provides robust performance under varying load conditions. Designed as a standard IndraDyn S product, it excels in applications requiring consistent speed and torque with minimal electrical noise.
Incorporating Natural Convection cooling, the MSK100A model maintains optimal operating temperatures without auxiliary fans, reducing maintenance and improving reliability. The built-in Hiperface optical encoder interface supports 128 signal periods per revolution and singleturn resolution, enabling high-precision feedback for demanding servo loops. At a Continuous Torque at Standstill (100 K) of 17.0 Nm and a Continuous Current at Standstill (100 K) of 11.6 A, the motor ensures smooth startup and accurate positioning. Its Maximum Torque of 54.0 Nm and four pole pairs deliver exceptional dynamic response for high-performance motion tasks.
Equipped with a With holding brake, electrically-released system providing 32 Nm of brake torque, the motor secures loads during power loss or standstill, enhancing safety and integration flexibility. The shaft with keyway design simplifies mechanical coupling and ensures reliable power transmission. The standard housing and B-side power connector facilitate installation in diverse machine architectures. Overall, this MSK100A synchronous servomotor offers exceptional durability, precise control, and efficient operation, making it an ideal choice for advanced industrial drive solutions.

Frequently Asked Questions
How does the Hiperface singleturn optical encoder (128 signal periods) in MSK100A-0300-NN-S1-BP1-NNNN enhance closed-loop positioning?
Its sine/cosine tracks enable fine interpolation and an immediate absolute reference within one revolution, cutting homing time and phase lag. Stable feedback increases servo stiffness and minimizes low-speed limit-cycle oscillations.
Why specify natural-convection cooling on MSK100A-0300-NN-S1-BP1-NNNN instead of adding an auxiliary fan?
Passive thermal dissipation reduces moving parts and maintenance, preserving the IP65 sealed envelope. Maintain vertical airflow clearance in the cabinet to achieve rated data across duty cycles and ambient limits.
What does a winding inductivity of 11,200 mH on MSK100A-0300-NN-S1-BP1-NNNN imply for the drive setup?
Higher phase inductance filters PWM ripple and attenuates current harmonics, easing EMI and acoustic noise. Tune current-loop bandwidth accordingly to maintain response while respecting voltage limits at speed.
How does the electrically-released 32 Nm holding brake support machine safety on MSK100A-0300-NN-S1-BP1-NNNN?
The spring-applied torque locks the axis at power-off or E-stop, preventing back-driving on vertical or overhauling loads. Its release is controlled electrically for enabling safe clamping during commissioning and emergency routines.
How do the 17.0 Nm continuous torque and 11.6 A continuous current (100 K) affect axis sizing?
They define sustained stall capability for static hold and low-speed cut. Its matching gearbox ratios and drive current margins to these values prevents thermal overload and preserves positioning repeatability.
