Product Description:
The MSK100D-0300-NN-M2-BP2-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Classified as a synchronous servomotor, it delivers closed-loop torque and position control to packaging lines, machining centers, and assembly gantries. Its rated frame, identified as motor size 100, allows it to drive mid-to-high inertia loads while maintaining smooth rotation in demanding automation cells.
The motor’s feedback system is based on the EnDat2.1 serial interface working with an optical sensor that produces 2048 signal periods per revolution; the multi-turn absolute format preserves position data through power cycles and eliminates homing routines. Increased concentricity of the rotor-stator air gap minimizes cogging and improves speed uniformity. Cooling is handled entirely by natural convection, so heat is dissipated through the housing without forced airflow. Length code D and winding code 0300 identify the active stack and electrical characteristics that match this unit to IndraDrive controllers of the appropriate current range. The power connector is installed on the B-side to simplify right-angle cable routing inside cabinets. The housing is sealed to IP65, preventing dust ingress and resistance to directed water spray.
An electrically released holding brake equips the unit for vertical axes. It delivers 70 Nm of static torque to secure the load whenever supply power is removed. The output shaft is a shaft with keyway, which transfers torque without slip and simplifies coupling alignment within gearboxes or pulleys. Thermal endurance matches class 155 insulation, allowing continuous service while windings remain below the designated temperature limit in ambient conditions of 0–40 °C. This arrangement suits axes that must remain stationary during stops.
