Product Description:
The MSK100B-0450-NN-S1-BP1-NNNN is a three-phase AC servomotor manufactured by Bosch Rexroth Indramat and listed in the MSK IndraDyn S Synchronous Motors series. It functions as an electromechanical actuator that delivers tightly regulated position and speed for industrial axes driven by Rexroth drive controllers. By combining a permanent-magnet rotor with an integrated optical encoder, the unit supplies real-time feedback required for coordinated motion in assembly cells, pick-and-place modules, and other automated equipment.
The motor relies on natural convection to move heat away from its stator, so cabinet airflow or external fans are not required when mounting space allows free air circulation. Position data is transmitted through the Hiperface interface, and the optical scale inside the encoder produces 128 signal periods per mechanical revolution; this resolution supports fine velocity loops and tight positioning tolerances. During power-off events, an electrically released brake applies 32 Nm of static holding torque to keep vertical or suspended loads from drifting. The housing carries a sealing classification of IP65, which blocks dust ingress and resists water jets, allowing direct installation on machinery without additional protective covers.
A single-turn measuring system is used, meaning the encoder reports absolute rotor angle within one revolution, which simplifies homing routines when power resumes. Torque is transmitted through a balanced shaft with a keyway, giving installers a standardized method to lock pulleys or couplings. Rated operation is specified for ambient temperatures between 0–40 °C, so continuous duty outside that window requires derating or supplemental cooling. The windings employ Class 155 insulation to tolerate internal hotspot temperatures generated by dynamic cycles. Additional mechanical parameters include size 100 laminations, a B-length stator stack, a 0450 winding code chosen for medium base speed, and a power connector positioned on the motor’s B-side to streamline routing in multi-axis assemblies.
