Product Description:

The MSK071D-0450-FN-S3-AG0-NNAN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a high-precision rotary actuator, the unit delivers closed-loop torque and speed control for positioning axes and continuous-motion drives in automated machinery. This type of motor is used where stable speed regulation and accurate positioning must be maintained under changing load conditions. Its naming code indicates a frame size 071 housing and a D-length package, giving it a compact profile for medium-power applications while maintaining the reduced runout needed for accurate load coupling.

Thermal management is handled by liquid cooling, so waste heat is removed through a coolant circuit rather than by air, which helps keep stator temperatures low during extended duty cycles. Liquid cooling also reduces dependence on surrounding panel airflow. An IP65 enclosure protects internal components against dust ingress and water jets, and the Class 155 insulation system supports winding temperatures associated with continuous servo operation. The motor can run in ambient conditions from 0 to 40 °C without derating. A plain shaft supports direct coupling to external transmission elements. This design supports high torque density while keeping mounting dimensions consistent with the series.

The integrated feedback system uses the Hiperface digital interface with a 16 signal periods capacitive sensor, so absolute rotor angle data is delivered with strong resistance to electrical noise. This feedback arrangement supports accurate commutation and position evaluation during normal servo operation. Because the feedback element is single-turn, the position value repeats after each full revolution, which suits short-stroke axes that re-reference routinely. Power conductors exit on the A-side, which supports straightforward cable routing. The motor is assembled without a holding brake, so position holding must be provided by the drive or by external mechanics when power is removed. In the model code, 0450 corresponds to the electrical characteristics that must match the connected servo amplifier.
