Product Description:

The MSK071D-0450-NN-S1-BG0-NNAN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It serves as a drive element in industrial automation, supplying controlled torque and position feedback for axes that require precise motion control. Integrated feedback allows the connected drive to regulate position and speed with high accuracy during repeated machine cycles. A reduced runout mechanical design also supports stable coupling in applications that depend on smooth rotary motion.

Heat is removed solely by natural convection, so airflow around the frame is sufficient and no fan or liquid circuit is required. The enclosure carries a protection rating of IP65, which keeps dust out and protects internal components against water jets. Feedback is supplied through a Hiperface interface that connects the integrated optical encoder to the drive. That encoder resolves rotor position over 128 signal periods, giving the controller precise electrical angle information during operation. The motor uses a plain shaft, which avoids keyways and simplifies coupling to precision gearheads or clamp-style hubs.

The motor is intended for continuous operation in ambient air from 0–40 °C, making it suitable for typical machine installations. The encoder uses a single-turn configuration, so one mechanical revolution produces a complete absolute position value before it repeats. Thermal endurance corresponds to insulation class 155, which supports winding temperatures up to 155 °C. Electrical behavior matches winding code 0450, which the drive uses for the appropriate resistance and inductance values. The motor has size 071 with length D, the power connector is located on the B-side, and the unit is supplied without a holding brake.
