Product Description:

The MSK071D-0450-NN-M1-UP1-NSNN is a servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a direct-drive rotary actuator, it supplies commanded torque and position feedback to tightly controlled axes in packaging machines, printing lines, and similar automated stations. The integrated optical encoder and keyed shaft arrangement support accurate closed-loop motion and repeatable power transmission in electric drive systems, including applications with frequent starts and stops.

This motor is cooled by natural convection, so heat is removed through the housing fins without external fans, which simplifies airflow requirements around the installation. An electrically released holding brake generates 23 Nm of static torque, providing load security when power is removed and disengaging automatically during motion. Position data is exchanged over the Hiperface interface, allowing motor feedback and electronic nameplate data to be transmitted to compatible drives. Inside the encoder, 128 signal periods per mechanical revolution are interpolated by the drive to support high-resolution speed control. Because the measuring system is multi-turn absolute, the shaft angle and revolution count are retained after shutdown, which reduces the need for homing after restart.

The feedback connector is rotatable through 240°, so the cable exit can be aligned within that arc to fit tight machine spaces and reduce torsion on the connector body. In hazardous areas, the motor uses a standard design with explosion protection for applications where ignitable atmospheres may occasionally be present. Torque is transmitted through a shaft with a keyway, which mates with keyed couplings and helps prevent angular slip under peak loads. The motor uses Length D within the MSK size 071 frame, and the 0450 winding code matches its voltage constant and current demand to medium-power IndraDrive controllers.
