Product Description:

The MSK100B-0300-NN-S2-AP0-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers precise torque and position control to automated axes, pick-and-place stations, and packaging machinery. By integrating a high-accuracy feedback encoder with carefully machined rotor components, the unit supports closed-loop motion tasks that demand consistent cycle times in industrial automation cells. It is suited for applications that require accurate response during repeated start-stop motion.

Its cooling relies on natural convection, so housing fins dissipate heat without fans, simplifying cabinet airflow design. Position data are transferred through the EnDat2.1 serial interface, allowing bidirectional communication between the drive and controller. The optical scale inside the encoder produces 2048 signal periods per revolution, and that fine pitch, together with the optical sensor path, yields very high interpolated position resolution. Because the element is a single-turn device, it reports absolute position within one revolution, while multirevolution tracking remains the task of the higher-level control system.

The housing is rated IP65, allowing installation in dusty or splash-prone zones while protecting internal components. Continuous operation is specified for ambient temperatures from 0 to 40 °C, and the windings use thermal class 155 insulation to tolerate internal hot-spot conditions encountered during dynamic duty cycles. Power and feedback connectors exit on the A-side to keep wiring clear of moving parts, and the shaft profile is a shaft with a keyway for rigid coupling to gearboxes or pulleys. Additional build details include motor size 100, length code B, winding code 0300, the increased concentricity machining option, and construction without a holding brake.
