Product Description:

The MSK075E-0200-NN-S3-UG1-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed as a compact drive element, it converts electrical power into precisely controlled mechanical motion so that positioning, contouring, or feed axes in industrial automation systems run with close torque and speed tolerances. Its brushless construction and sealed housing make it suited for integration into machine tools, packaging lines, and material-handling gantries where feedback-based accuracy is required.

Heat is removed through natural convection, so only ambient airflow around the housing is required. A rotatable 240° connector allows the feedback plug to be aligned without twisting cables, and the signaling travels over the Hiperface interface so drive controllers receive absolute position data. Internal position sensing relies on a capacitive single-turn encoder that delivers 16 signal periods per revolution, providing coarse resolution that the controller interpolates for fine commutation. When motion stops, an electrically released holding brake supplies 23 Nm of static torque to secure vertical or inertially loaded axes. The enclosure carries an IP65 rating, which blocks dust and low-pressure water jets from reaching the windings and encoder in typical shop-floor environments.

The drive end uses a plain shaft, simplifying coupling to gearboxes or belt pulleys and avoiding keyway-induced stress concentrations. The motor uses class 155 insulation, and size code 075 indicates the frame dimension used for this model, while motor length E and winding code 0200 determine its active stack and electrical setup. All ratings apply at ambient temperatures of 0–40 °C, which keeps brake operation, encoder performance, and convection cooling within the intended operating range.
