R911318380
The R911318380 (MSK071E-0300-NN-S1-UP2-NNNN), developed by Bosch Rexroth Indramat, is a high-performance synchronous servo motor. Notable for its use in machine tools, metal forming machines, and robotics, it is part of the innovative MSK series included in the IndraDyn S family. This motor features maintenance-free operation for up to 30,000 operating hours when utilized within the manufacturer's recommended parameters. Equipped with a single-turn absolute encoder with the Hiperface interface, the motor offers highly accurate position detection and speed control within an accuracy of ±80 angular seconds. The encoder also incorporates a data memory to streamline the startup process and ensure compatibility with the drive controller.
Structurally, the R911318380 (MSK071E-0300-NN-S1-UP2-NNNN) comprises an output shaft designed with a keyway as per DIN 6885-1, providing consistent transmission of torques and reducing requirements for the shaft-hub connection. A shaft sealing ring designed following the DIN 3760 – Design A adds durability to the structure. Integral to the motor’s stator is the KTY84 thermal sensor, an inducible temperature monitoring system which prevents damage due to thermal overload. Performance-wise, at its peak, this motor can achieve an impressive 4,200 revolutions per minute, taking a maximum of 56.3A current and can reach a maximum torque of 84.0Nm, demonstrating its industrial capabilities.
