Product Description:

The MSK100C-0300-NN-S1-BP0-NNNN is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is built to deliver commanded torque and speed in industrial automation cells, allowing coordinated axis control for packaging lines, material handling modules, machining centers, and other servo-driven equipment. By responding quickly to drive commands, the unit translates electronic position requests into mechanical rotation, supporting closed-loop motion sequences that demand high repeatability during start, stop, and repeat-position cycles.

The motor uses a standard design with motor length C and winding code 0300, which set its overall stack height and electrical characteristics. Cooling relies solely on natural convection, so heat leaves the frame through surface radiation and ambient airflow without forced ventilation. Position feedback is provided by a Hiperface interface, and the optical sensor inside generates 128 signal periods per revolution. Because the scanning principle is optical, incremental and absolute tracks are read without physical contact, reducing wear. The feedback system is a single-turn arrangement, so absolute position is available for one mechanical revolution, which is sufficient for axes that home to a fixed reference after startup.

The motor is supplied without a holding brake, so external locking devices or drive torque must secure the load when power is removed. Frame designation 100 specifies the stator diameter, giving compatibility with gearboxes and flanges sized for this motor family. Power leads exit on the B-side, allowing cable routing away from the driven load when the motor is mounted in typical horizontal orientations. A shaft with a keyway simplifies torque transmission to pulleys or couplings while helping prevent slip during repetitive duty cycles and in coupling arrangements that require positive mechanical engagement.
