MSK103A-0300-NN-S2-UG0-NNNN

The MSK103A-0300-NN-S2-UG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servomotor intended for closed-loop position and velocity control in industrial automation, where precise torque delivery and feedback accuracy are critical for coordinated motion axes.

This model uses Natural convection as its cooling method, so thermal energy is carried away only through the surface of the housing instead of by forced air or liquid circuits. A Plain shaft transmits torque directly to couplings or gear stages without keys, reducing concentricity error and simplifying assembly. Feedback communication is handled through the EnDat2.1 digital interface, enabling absolute position data exchange with compatible drive controllers. The integrated optical encoder generates 2048 signal periods per mechanical revolution, giving the control system high-resolution information for smooth speed regulation. Mechanical holding is external because the motor is supplied without a holding brake; systems that require static load support must use alternate braking or clamping devices.

The feedback connector is Rotatable, 240°, allowing the cable outlet to be aligned during installation and helping maintain minimum bend radii inside crowded cabinets. Encoder scanning relies on an Optical principle, which uses a light source and code disc to achieve fine positional granularity with low electrical noise. Position data is absolute within one turn because the encoder is classified as Singleturn, simplifying homing routines in machines with limited travel. Electromagnetic characteristics follow winding code 0300; this designation fixes coil resistance and inductance so that drive sizing and peak current limits are predictable. Additional identifiers include motor size 103, length A, and a standard mechanical design, which together define the overall frame dimensions and mounting interfaces.
