Product Description:

Bosch Rexroth Indramat produces the MSK100B-0400-NN-M2-BG1-RNNN as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor functions as a rotary actuator that provides precise torque output and position feedback for automated machine axes. By combining a compact housing with high-resolution feedback, the unit is used in packaging lines, metal-cutting centers, and material-handling stations where deterministic motion is required. Its synchronous design supports controlled acceleration and repeatable positioning on servo-driven equipment.

The stator windings are cooled by natural convection, removing heat through the housing without external fans. A housing protection rating of IP65 seals the frame against dust ingress and low-pressure water jets so the motor can be mounted near the working process. Position data are transmitted through the EnDat2.1 interface, and the optical sensor inside the encoder produces 2048 signal periods per revolution for fine incremental positioning. An electrically released holding brake supplies 32 Nm of static torque to lock the shaft during power-off conditions, and the power connector is arranged on the motor's B-side to keep cabling parallel with the machine bed. Increased concentricity machining minimizes radial runout and vibration.

The feedback device stores rotational count information in multi-turn absolute format, eliminating homing cycles after shutdown. A plain shaft transfers torque through a clamped coupling, and the dimensional code corresponds to motor size 100 with length class B for higher continuous power than shorter variants. The unit operates within 0–40 °C ambient limits, matching typical industrial conditions. Insulation system 155 permits winding temperatures up to 155 °C before thermal derating begins, while winding code 0400 indicates the electrical characteristics used by the matching drive to calculate current limits.
