Product Description:

The MSK100A-0450-NN-S1-BP0-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a standard-design rotary actuator, it converts regulated electrical energy from a drive into precise mechanical rotation. This supports positioning and velocity control in automated machinery, packaging lines, and material-handling stages. With a compatible controller, it can be used on axes that require repeatable starts, stops, and speed changes.

The motor is cooled by natural convection, so heat leaves the frame through surface radiation and ambient airflow without fans or liquid circuits. Feedback is delivered through a Hiperface interface that carries both position data and electronic nameplate information to the drive. Inside the encoder, light-grid scanning of a coded disk implements optical sensing, reducing hysteresis-related measurement error. For vertical or safety-critical axes, an external brake must be used because the unit is supplied without a holding brake. Torque is transferred through a shaft with keyway, giving positive mechanical engagement to pulleys or couplings while maintaining repeatable phasing. Connections for power are placed on the B-side of the housing, which helps route motor cables away from the encoder side.

The position sensor resolves one revolution into 128 signal periods, and because it is a single-turn device, absolute position information resets after each full rotation. Frame code 100 indicates the stator diameter, giving the motor the thermal mass used in this size class. Motor length A shortens the stack to reduce axial footprint when the application favors compactness over peak power. The electromagnetic characteristics follow winding code 0450, which sets the coil resistance and inductance so the matched drive can supply current without oversaturation and maintain smooth torque across the speed range. This layout is useful in compact machine sections where installation space is limited but controlled servo motion and stable feedback are still required.
