MSK075E-0450-FN-S2-UG2-RNNN

The Bosch Rexroth Indramat MSK075E-0450-FN-S2-UG2-RNNN synchronous servomotor delivers high dynamics and robust design in the MSK IndraDyn S Synchronous Motors series. Manufactured by Bosch Rexroth Indramat, this part_number features an IP65 protection class for reliable operation in harsh environments and is built with Class F insulation to ensure thermal endurance. The servomotor includes an electrically released holding brake with 30 Nm holding brake torque for secure stopping and fail-safe applications. A liquid cooling mechanism maintains optimal thermal management during continuous operation, making the unit suitable for demanding industrial use.

The MSK075E-0450-FN-S2-UG2-RNNN is designed with increased concentricity and a plain shaft configuration, optimizing rotational accuracy and reducing mechanical run-out. The motor utilizes an optical encoder with EnDat2.1 encoder interface, 2048 signal periods resolution, and a rotatable 240° encoder connector for flexible installation. Its winding code 0450 corresponds to a motor size 075 and length designation E, enabling straightforward identification and compatibility. The device requires cooling constraint FN and supports singleturn encoder technology, ensuring precise position feedback and minimal drift.

Operational performance is characterized by a continuous torque at standstill of 23.0 Nm and a continuous current at standstill of 15.6 A at 100 K. Peak demands are met with a maximum torque of 88.0 Nm and a maximum current of 63.9 A, while the winding inductivity of 4,460 mH governs current rise time and dynamic response. The unit withstands radial and axial forces under any mounting orientation, including B5 flange installation, and must be grounded correctly before commissioning. The Class F insulation rating, combined with an explosion-protected design compliant with 2014/34/EU directives, ensures operational safety in potentially explosive atmospheres.

Integration into motion control systems is achieved through compatibility with Bosch Rexroth drive controllers, guaranteeing coordinated performance and safety interlocking. The servomotor is UL Listed and CSA Certified, facilitating global deployment in sectors such as chemical processing, petrochemical plants, and hazardous material handling. Its precise encoder feedback, robust brake system, and liquid cooling make it ideal for robotic arms, rotary indexing, and high-speed packaging equipment. The MSK075E-0450-FN-S2-UG2-RNNN combines high torque density and environmental resilience for critical industrial automation applications.
