Product Description:
The MSK100B-0300-NN-M2-LG0-RNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servo motor intended for precise position and speed control in automated machinery. The unit has a size 100 frame and length code B, giving it the physical envelope needed for mid-range torque applications while keeping installation dimensions consistent within the MSK family.
Heat is removed by natural convection, so the housing must be mounted where free airflow can carry thermal energy away without fans or liquid circuits. Rotor feedback comes from an optical encoder that communicates with the drive through the EnDat2.1 interface; the signal is produced at 2048 signal periods per mechanical turn, allowing fine interpolation inside the controller. The encoder is a multiturn absolute device, meaning the actual shaft angle and the number of complete revolutions are retained even after power loss, which simplifies homing routines. A protection rating of IP65 seals the stator against dust ingress and low-pressure water jets, enabling cabinet-free mounting in standard industrial areas. The motor uses an increased concentricity design, which minimizes radial runout and improves coupling accuracy with gears or belt pulleys.
The power connector is arranged on the left side, so routing of the main cable can match machines that place drives on the motor’s left. Continuous duty is specified for ambient temperatures between 0 to 40 °C; operation outside this window would require derating or extra cooling. The motor has a plain shaft, which permits backlash-free clamping hubs or shrink-fit couplings in servo loops that cannot tolerate keyway play. Thermal class 155 insulation supports winding temperatures up to 155 °C under cyclic loads. The 0300 winding code matches electrical characteristics to converters intended for high-response motion, and the motor is supplied without a holding brake when static load retention is handled by the drive or external mechanics.
