Product Description:

The MSK071D-0450-NN-M1-UP2-NSNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It occupies motor size 071 with length code D and serves as a torque-generating axis element that couples directly to precision machinery through its keyed shaft. In automated cells, its closed-loop feedback allows a drive controller to position loads accurately without external gear reduction.

This motor belongs to the Standard and Explosion Protection design line and uses Cooling FN, which removes heat through natural convection instead of forced airflow. The housing complies with IP65, so internal components remain sealed against dust and low-pressure water jets. An electrically released holding brake delivers 30 Nm of static torque for load retention whenever power is removed. Position data are transmitted over the Hiperface serial interface through a rotatable 240° connector, which helps simplify cable routing. The integrated optical encoder operates as a multi-turn absolute device, and the winding code supports compatible drive operation.

The encoder samples rotor movement in 128 signal periods per revolution using an optical scanning method, enabling fine velocity control without external sensors. A shaft with keyway provides positive mechanical locking to couplings, and the electrically released brake is disengaged during normal powered operation. Continuous operation is specified for ambient temperatures of 0 – 40 °C, aligning with typical control-cabinet climates. Thermal Class 155 insulation supports winding temperatures up to the class limit during cyclic duty. The multi-turn structure records full revolutions even when power is absent, and the 240° rotatable connector helps reduce strain on feedback wiring during installation or service work.
