Product Description:

The MSK070C-0450-NN-M1-UG1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it performs closed-loop torque and position control for automated machinery, positioning tables, and packaging axes. By integrating an optical encoder and an electrically released holding brake, the unit delivers repeatable motion while also locking the shaft at standstill when power is removed.

Thermal management relies on natural convection, so the housing must be mounted where unrestricted airflow can carry heat away without forced fans. Feedback signals are exchanged through the Hiperface interface, which allows digital position data and analog sine-cosine tracks to share one cable for drive compatibility. The optical reader resolves 128 signal periods per mechanical revolution; when the drive interpolates these signals, the fine subdivision supports very precise linear positioning. Because the scanning principle is optical, the encoder resists magnetic stray fields that could disturb inductive sensors. The motor follows a standard design format used within the MSK series.

Complementing the feedback chain, the encoder carries multi-turn absolute position tracking, so the drive powers up with exact angle and revolution information even after movement during power-off. Static axis clamping comes from a holding brake rated at 23 Nm. Drive torque is transmitted through a plain shaft, so coupling selection must rely on friction or shrink-fit connections. The 070 frame size gives a stator diameter that balances torque density with compact width, while winding code 0450 matches the copper layout and resistance to compatible inverters. Length code C and the rotatable 240° encoder connector support flexible routing in confined cabinets.
