Product Description:
The MSK071E-0450-NN-M1-AG1-NNAN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It functions as a torque-controlled rotary actuator in automated packaging lines, metal-cutting centers, and material-handling axes. The motor has size 071 and length E, and its reduced runout design supports precise shaft alignment where tight positional repeatability is required. This layout suits automated axes that need stable motion during repeated starts, stops, and directional changes.
Heat generated by the stator is removed through natural convection, so no external blower or liquid circuit is required, and clearance for free airflow should be reserved around the frame. An enclosure rating of IP65 helps protect the housing against dust ingress and water jets in demanding industrial settings. The electrically released brake provides 23 Nm of static holding torque, which helps keep a vertical axis in place when drive power is removed. For feedback, the motor uses the Hiperface serial interface, and its optical encoder provides 128 signal periods per mechanical revolution for smooth closed-loop control. The brake is intended to hold the axis at standstill rather than to perform repeated dynamic stopping.
The encoder is a multi-turn absolute device, so the drive retains the true shaft position across power cycles without external battery backup. A plain shaft with reduced runout helps minimize coupling vibration and supports accurate alignment with connected transmission components. The permitted ambient temperature range is 0–40 °C, and the insulation system is rated to 155 for continuous-duty operation at elevated internal temperatures. Power is routed from the A-side connector, which helps separate cable paths in compact machine layouts. Winding code 0450 and the housing style are used for the torque-speed curve applied during axis sizing.
