Product Description:
Bosch Rexroth Indramat manufactures the MSK050C-0450-NN-S1-UG0-NNNN as part of the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it delivers closed-loop torque and speed for indexing tables, gantry axes, and material-handling stations in automated lines such as carton formers and labeling cells. The compact frame and standardized mounting pattern allow the motor to be coupled directly to gear stages or belts, which helps conserve space in densely packed machines. This layout also suits servo-driven axes that need repeatable starts, stops, and direction changes during continuous production.
It dissipates heat through natural convection, so the machine cabinet need not include forced-air ducts or liquid manifolds. The mechanical design is standard, avoiding custom flanges or housings. Position feedback is provided by an optical encoder whose connector can be rotated 240°, allowing cable exit to match panel layouts and avoid awkward bends. Communication to the drive occurs through Hiperface, and the sensor resolves rotor position into 128 signal periods per revolution; because the system is single-turn, the controller receives absolute position only within one mechanical turn. The housing meets IP65 protection, and the motor is supplied without a holding brake, so any load that must remain fixed at standstill needs external holding force.
The motor is intended for ambient temperatures from 0–40 °C, allowing placement near process equipment without auxiliary climate control. A hardened plain shaft transmits torque without keyways and is suited for shrink-fit or clamp couplings that favor low backlash and accurate alignment. Coil insulation rated to Class 155 permits elevated internal temperature before derating. Winding code 0450 matches the current and voltage characteristics expected by compatible drive modules for this C-length stator. In the 050 frame size, that combination supports compact axis layouts where responsive motion and consistent servo control are required.
