Rexroth MSK076C-0450-NN-M1-UG1-NNNN Synchronous Servo Motor
The Rexroth MSK076C-0450-NN-M1-UG1-NNNN is a high‑power‑density synchronous servo motor from the IndraDyn S MSK series, engineered for precision motion control in demanding industrial environments. As a size 76 frame, length C model with winding code 0450, the Rexroth MSK076C-0450-NN-M1-UG1-NNNN delivers robust torque performance while maintaining a compact, space‑saving design. It features a plain shaft with sealing rings for reliable mechanical connection and IP65 protection, ensuring resistance to dust and water ingress in harsh conditions. The Rexroth MSK076C-0450-NN-M1-UG1-NNNN is equipped with a multiturn absolute optical encoder (Hiperface interface, 128 signal periods) for high‑accuracy position and speed feedback, supporting closed‑loop control with exceptional repeatability. Its natural convection cooling design simplifies installation while maintaining stable thermal performance, and the 240° rotatable power connector enhances flexibility in system layout. With insulation class EN 60034‑1 (F), the Rexroth MSK076C-0450-NN-M1-UG1-NNNN meets stringent safety and reliability standards for continuous operation.
