Product Description:
The MSK050C-0450-NN-S1-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated machinery, it delivers tightly regulated torque and speed so that axis modules, gantries, and packaging equipment can follow programmed motion profiles with minimal deviation. By combining precision feedback with an electrically released holding brake, the motor supports positioning tasks that require rapid cycling and secure standstill when power is removed. This arrangement suits servo axes that must start, stop, and hold position repeatedly during normal machine operation.
Heat generated in operation is removed by natural convection, eliminating the need for external blowers and simplifying cabinet layouts. The frame code 050 and the compact length code C keep the overall envelope small, while the standard mechanical design maintains compatibility with common MSK mounting flanges and connectors. A 6 Nm electrically released holding brake secures the load when the drive is disabled, which is useful on vertical axes or at controlled stops. The motor also has a plain shaft for connection to zero-backlash couplings or gear stages without a key seat.
The motor uses winding code 0450 for a balanced torque-to-current ratio in medium-inertia applications. Position data is supplied through a Hiperface optical encoder that produces 128 signal periods per revolution. Because the scan head is single-turn, absolute position is retained over one mechanical turn, while any additional turn counting is handled in the control system. The feedback plug is rotatable through 240°, allowing the cable to exit in a preferred direction during installation. Optical sensing also helps support stable position feedback on short-stroke and repetitive-motion axes.
