Product Description:
The MSK040C-0450-NN-M2-UG1-NNNK is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it converts commanded current from a drive controller into rotational motion for compact tooling axes, indexing tables, or feed drives that demand high positioning accuracy and repeatability. Its design suits servo applications that need quick response, stable torque delivery, and reliable motion control in limited installation space.
This motor uses natural convection as its cooling method, so heat is removed through the housing surface without external fans or liquid circuits. Position data is returned to the control loop through an EnDat2.1 serial interface that supports error-checked communication and automatic parameter transfer. The integrated optical encoder resolves movement into 2048 signal periods, and because its scanning principle is optical, it maintains fine incremental tracks with low hysteresis over the speed range. Its feedback device is a multiturn absolute unit, so it counts complete revolutions internally and reports absolute shaft position even after power loss. The encoder connector can be rotated relative to the stator shell, allowing cable exit to align more easily with machine routing.
An electrically released brake provides a holding torque of 4 Nm to secure vertical loads when the drive is de-energized. The feedback connector is rotatable through 240°, which reduces strain on leads inside tight enclosures and supports flexible cable routing. Motion is transferred through a plain shaft that avoids keyway stress concentrations and suits clamp couplings. The motor uses winding code 0450, which sets the electrical values expected by compatible drive sizing tools. Motor size 040 and length C place the unit in a compact frame for installations where mounting space is limited.
