Product Description:

The MSK040B-0450-NN-M1-UP0-NSNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive power into tightly regulated torque and speed for positioning axes, pick-and-place heads, and packaging stations in automated lines. Configuration choices such as winding code 0450, a length B housing, and an integrated optical feedback system allow it to pair with Rexroth drive amplifiers for closed-loop motion tasks.

Heat is removed by natural convection, eliminating the need for fans. A sealed aluminum frame rated IP65 blocks dust and water jets so the unit can be mounted directly on machinery frames. Motion feedback travels through the Hiperface digital link, which transfers both position and diagnostic data. The embedded sensor delivers 128 signal periods per mechanical turn, and its multiturn absolute memory allows the control electronics to retain position information across power cycles. The motor also uses insulation class 155, which allows winding temperatures up to 155 °C at peak duty. Because it is supplied without a holding brake, the load must be secured by external clamping or drive torque when power is removed.

The encoder connector can be rotated through 240°, allowing cable routing to fit cramped enclosures or gantry channels. Position detection is based on an optical scanning principle that resists drift and preserves phase alignment over long service intervals. Continuous service is permitted in ambient temperatures from 0 to 40 °C, which matches typical factory floor conditions. Output torque is transmitted through a shaft with keyway, so pulley hubs or rigid couplings have a positive anti-slip drive interface. The motor includes a standard explosion-protection design option for use in automated lines that handle volatile media.
