Product Description:

The MSK071E-0300-NN-S1-UG1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and positioned within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts electrical energy into precisely controlled rotary motion for automated positioning, indexing, and speed-regulated tasks in industrial machinery. When paired with a compatible drive, the motor supports accurate speed control and repeatable positioning in machines that cycle frequently and require stable motion response.

This model relies on Natural convection for thermal dissipation, so it can be mounted without external fans when surrounding airflow is sufficient. A rotatable 240° encoder connector simplifies cable routing when the motor is installed in confined spaces or near adjacent machine components. Feedback is transferred over the Hiperface interface, and the optical encoder produces 128 signal periods per mechanical revolution, allowing tight velocity and position loops. The Optical sensing principle improves repeatability by reducing drift and avoids the wear associated with mechanical tachometer elements. The plain shaft design suits clamp or coupling fixtures that do not require a keyed interface, and the housing follows the standard construction style used for this size range.

Position data are absolute over one turn because the encoder is a Singleturn device, which simplifies homing routines in applications with short travel ranges. An electrically released holding brake provides 23 Nm of static torque, preventing back-driving when power is removed from vertical or load-bearing axes. The motor has length code E and frame size 071, which correspond to the active stack height and flange geometry used for this version. Its winding code is 0300, which allows compatible drive controllers to use the expected current and voltage values for the motor.
