Product Description:

The MSK100C-0300-NN-S3-AG0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it provides closed-loop torque and speed control for indexing tables, gantry axes, and packaging stations where precise positioning is required. Within an automation line, it integrates with compatible drive controllers to convert electrical command signals into regulated mechanical rotation for accurate and dynamic motion sequencing.

The motor relies on natural convection for heat dissipation, so its housing transfers thermal energy to surrounding air without forced airflow. An integrated SICK encoder communicates over the Hiperface interface, allowing absolute position feedback to the drive with 16 signal periods per revolution. This resolution supports tight velocity loops during rapid reversals. The stator and connection box are sealed to an IP65 rating, preventing dust ingress and guarding internal windings against water jets encountered during washdown cleaning. Rated operation is allowed in ambient temperatures from 0 to 40 °C, ensuring full torque delivery in factory environments without derating calculations. The power connector is positioned on the A-side of the endbell, and a plain shaft simplifies mounting to gearboxes or timing pulleys.

The unit follows the standard mechanical design and is supplied without a holding brake, while its Class 155 insulation system supports extended duty cycles. The winding identified by code 0300 sets the voltage constant and current rating for mid-power axes, while the frame size 100 provides a larger stator diameter for higher torque density. Length designation C extends the magnetic stack so continuous output can be achieved without forced cooling. Position sensing is based on a single-turn scale that reports one absolute revolution, and its capacitive scanning principle tolerates vibration and oil mist better than optical discs.
