Product Description:

The MSK071D-0450-NN-S1-UG2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, the unit supplies controlled torque and speed so axis drives can follow precise motion profiles without mechanical backlash. Integrated feedback supports closed-loop positioning, while the holding brake helps keep the axis secure when drive torque is removed. These features make the motor suitable for packaging lines, material-handling stages, and processing equipment that require repeatable motion and stable stopping behavior.

With frame designation 071, the motor uses the IEC mounting footprint associated with a 71 mm stator core diameter. The extended housing identified by D adds active length for higher continuous power density. Winding code 0450 indicates the copper fill and turns ratio, matching the motor to compatible drive voltage and current ranges. Heat is removed by natural convection, so installation space must allow free airflow instead of relying on forced fans. Position feedback is generated by an optical encoder assembly, which provides high resolution and strong immunity to magnetic interference during high-speed operation.

Signal exchange between the encoder and the drive occurs through the Hiperface serial interface, and the connector uses a design that is rotatable through 240° to help align cables in tight cabinets. The feedback element is single-turn, so it provides absolute position information for one mechanical revolution and suits many rotary axes that are homed at power-up. A holding brake rated at 30 Nm clamps the shaft when the drive disables torque, and because the brake is electrically released, it engages automatically during power loss. The plain shaft supports direct coupling to gearboxes or clamping hubs. Cooling class FN indicates that the housing depends on unobstructed natural airflow and should not be placed in a sealed enclosure that blocks heat dissipation.
