MSK050C-0300-NN-M1-UG1-NNPN

The Bosch Rexroth Indramat MSK050C-0300-NN-M1-UG1-NNPN servo motor from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor with a Motor Size 050 and Motor Length C. It achieves a maximum speed of 4700 rpm while maintaining a thermal time constant of approximately 14 min. The winding is designated by code 0300, delivering consistent electromagnetic performance with a Winding Inductivity of 45,100 mH. Designed for reliability in Zone 2 and Zone 22 applications, it features a secondary ground conductor with a minimum cross-section of 4 mm2 to ensure safe equipotential bonding.

The motor integrates a robust Multiturn Absolute encoder system based on Optical Encoder Technology and a Hiperface Encoder Interface supporting 128 signal periods per revolution. A rotatable, 240° Encoder Connector provides flexible cable routing, while separate M23 circular connectors manage power and encoder signals. The output shaft employs a Plain shaft design with a radial shaft sealing ring for enhanced protection against contaminants and to preserve corrosion resistance. A frontal centering hole and DS thread simplify coupling alignment during installation.

With a continuous standstill performance of 3.4 A current and 5.5 Nm torque at 100 °C, the unit can handle peak demands up to 12.4 A and 15.0 Nm torque without derating. Natural Cooling by convection suffices for typical duty cycles, and a holding brake electrically released at 24 V ±10% delivers 6 Nm braking torque when energized. The motor’s compact 233 mm overall length and zero-to-1,000 m installation altitude rating streamline integration across automation setups, making it a versatile and durable choice for precision motion control.
