Product Description:

The MSK071D-0450-NN-M2-UG1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. Designed as a rotary actuator for CNC axes and automated handling stations, the motor converts drive-controller commands into precise torque and position output for industrial machinery that demands accurate velocity control. Its frame size 071 and length D create a compact form factor suitable for medium-power tasks on packaging equipment, pick-and-place modules, and printing lines.

Its cooling relies on natural convection, so heat leaves the aluminum housing without added fans, which affects allowable mounting density and continuous-duty current. The stator carries winding code 0450, and an optical encoder transmits feedback through the EnDat2.1 interface, supporting single-cable solutions and electronic identification. Each mechanical revolution is divided into 2048 signal periods, supplying fine interpolated position data to the servo loop. An electrically released brake supplies 23 Nm of holding torque to secure vertical loads when drives are disabled. The enclosure is sealed to IP65, blocking dust and water jets so the unit can be mounted outside a cabinet when required.

Assembly and wiring flexibility are improved by the feedback plug, which is rotatable through 240°, permitting cable egress in four quadrants without twisting conductors. Power is transmitted through a plain shaft, suited for backlash-free clamp couplings that match the motor’s increased concentricity design. Continuous operation is specified for ambient temperatures from 0 to 40 °C, and an insulation system rated to class 155 endures elevated winding temperatures produced by fast cyclic moves. The multi-turn absolute measuring system preserves position data through power loss, while the natural-convection thermal path and D-length stator balance inertia against torque for responsive mid-range motion axes.
