Product Description:

The MSK040C-0450-NN-S3-UG1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It integrates into multi-axis automation cells where coordinated motion, fast positioning, and limited installation depth are required. By supplying regulated torque and speed feedback to a compatible controller, the unit converts electrical energy into rotary motion for conveyors, form-fill-seal actuators, or pick-and-place modules. This operating role makes it suitable for axes that must accelerate quickly, stop accurately, and repeat the same path over long production runs.

The motor is cooled solely by natural convection, so ambient air removes heat and no auxiliary fan or liquid circuit is necessary. Its housing is sealed to IP65, which helps protect internal components from dust and water jets in typical industrial settings. Position feedback relies on a Hiperface encoder; this bidirectional digital link transfers absolute rotor angle data to the drive for stable commutation and precise control. Internally, a capacitive sensor disc produces 16 signal periods, which the controller interpolates for finer position evaluation. The encoder connector can rotate 240 degrees to simplify cable routing, while the plain shaft mates directly with gearheads or pulleys. An electrically released brake clamps the rotor and can hold 4 Nm of static load for vertical or indexing axes.

The motor uses frame size 040 and stack length C, giving it a compact housing for installations with limited space. Thermal endurance corresponds to class 155, allowing the winding system to tolerate elevated operating temperature within the insulation limit. Reliable operation is permitted in ambient conditions from 0–40 °C, which covers normal factory environments without special cooling hardware. The compact envelope also helps when multiple axes must fit within a tightly packed machine layout.
