Product Description:
The MSK071D-0450-NN-S2-UG0-RNNN is manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This synchronous servo motor is built for closed-loop position and velocity control in automated assemblies, transfer systems, and processing lines. With motor size 071 and length D, it fits applications that need stable motion quality across varying loads. Increased concentricity in the mechanical design supports smooth rotation, and the motor is supplied without a holding brake, so static load retention must be provided by external hardware when power is removed. It is intended for servo axes that require repeatable starts, stops, and speed changes during regular machine cycles.
For thermal management, the motor relies on natural convection, eliminating the need for external fans while keeping the installation simple. A housing with an IP65 rating protects internal windings and the optical feedback hardware from dust ingress and low-pressure water jets. Position feedback is supplied through an EnDat2.1 interface, and the optical encoder produces 2048 signal periods for accurate interpolation in the controller. Cable routing is simplified because the encoder connector is rotatable through 240°, allowing the plug to be positioned away from adjacent machine panels and tight cable paths. This arrangement also helps preserve clearance around nearby guards, brackets, and cable runs.
The cylindrical output shaft is a plain shaft, permitting direct coupling with gearboxes or belt pulleys without keyways that could add imbalance. Rated operation is approved across an ambient range of 0–40 °C, making the motor suitable for common machine environments. Winding code 0450 identifies the electrical characteristics expected by the matching inverter, and insulation class 155 allows the winding system to withstand elevated internal temperatures during cyclic duty. The single-turn optical feedback and the improved concentricity support precise motion on axes that need repeatable positioning and stable speed control. This combination is well suited for machines that alternate between low-speed tracking and rapid indexing movement.
