MSK050C-0300-NN-M2-UG1-RNNN
MSK IndraDyn S Synchronous Motors
The MSK050C-0300-NN-M2-UG1-RNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors is a high-performance synchronous servomotor engineered for precision drive applications. It features a compact Product Type IndraDyn S design optimized for machine tools, robotics, and metal-forming equipment. The motor incorporates a robust Shaft Type plain shaft with increased concentricity per the Design DIN 42955 specification. An integrated Holding Brake ensures safe stops and holds loads without external hardware.
Built around a Motor Size 050 housing and a Motor Length C frame, this unit delivers a Maximum Torque of 15.0 Nm and continuous torque of 5.5 Nm at standstill 100 K. It draws a Continuous Current at Standstill 100 K of 3.4 A and spikes up to a Maximum Current of 12.4 A for rapid acceleration. The winding, coded Winding Code 0300, exhibits a high Winding Inductivity of 45,100 mH for smooth current transitions. Thermal management is handled via Cooling natural convection, while a multiturn absolute Encoder Interface EnDat2.1 provides Encoder Resolution of 2048 signal periods and a Encoder Connector rotatable 240° attachment.
Engineers will appreciate the MSK050C-0300-NN-M2-UG1-RNNN’s seamless integration into decentralized drives, leveraging its IP65-rated housing to withstand harsh factory environments. The electrically released brake with Holding Brake Torque of 6 Nm enhances safety without compromising cycle times. Rugged construction and precision encoder feedback ensure reliable, synchronized motion in printing machines, Cartesian robots, and high-speed machining centers.
