Product Description:

The MSK100B-0300-NN-M2-LG1-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides rotary actuation for positioning and speed control in automated machinery where closed-loop accuracy is required. The motor couples directly to drive axes, translating commanded current into proportional torque for conveyors, packaging tables, or gantry modules. Because it operates in a closed-loop system, the connected drive can correct speed and position errors as load conditions change during motion.

Thermal management is handled by natural convection, so the housing must be oriented to allow free airflow instead of relying on forced fans. Feedback is processed through the EnDat2.1 interface, and the integrated optical encoder supplies 2048 signal periods. This fine resolution lets the drive calculate position and velocity corrections with very small movement increments. An electrically released brake delivers 32 Nm of holding torque to secure vertical loads when power is off. The sealing system meets IP65, which helps block dust ingress and water jets during washdown cleaning. The rotor and stator geometry use an increased concentricity design that reduces cogging and supports smoother motion.

The output shaft has a plain shaft finish, allowing use with clamp or shrink-fit couplings without factory keyway machining. Operation is permitted at ambient temperatures from 0 to 40 °C, and the windings use class 155 insulation to withstand the related internal heat rise. Size code 100 and length code B describe the active core dimensions, while winding code 0300 corresponds to electrical values matched to this torque range. The encoder has Multiturn Absolute capability, so it retains position information across power cycles without external batteries. A left-side power connector simplifies cable routing along machine frames and supports installations where cable entry is limited to one side of the motor.
