Product Description:

The MSK075E-0300-FN-M1-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It combines the compact 075 frame with the E length to supply controlled rotary power for automated positioning and speed-regulated axes in packaging machinery, material handling, and general assembly equipment. As a closed-loop electromechanical actuator, the motor converts output from a compatible IndraDrive inverter into precise shaft motion, while the integrated optical encoder lets the drive monitor rotor position during operation. This makes the motor suitable for coordinated motion tasks that require repeatable acceleration, controlled speed changes, and accurate stopping at commanded positions.

Thermal management is handled through liquid cooling, so heat is removed directly from the stator jacket and higher continuous torque can be achieved without enlarging the housing. Because cooling does not rely on external air moving across the housing, the motor can fit machine layouts where space around the frame is limited. Position feedback is delivered over the Hiperface interface, and the optical sensor provides 128 signal periods per revolution together with absolute multi-turn data for immediate position availability at startup. The holding brake supplies 23 Nm of static torque and engages automatically when supply power is removed, helping prevent unintended axis movement. An enclosure rating of IP65 protects the windings and bearings against dust ingress and low-pressure water jets. The plain shaft design simplifies coupling to gears or pulleys without keyways or serrations.

The servo motor operates reliably between 0–40 °C, which suits typical machine-room conditions. Its insulation system is rated to Class 155, helping the winding withstand elevated internal temperatures during load peaks. The encoder connector can be rotated through 240°, giving more flexibility for cable routing in tight spaces, and the winding code 0300 matches the electrical characteristics used for this torque class. The rotatable connector also helps with cable routing when the motor is mounted near guarding or other machine structures.
