R911335346
The R911335346 (MSK070E-0300-NN-S2-UP1-RNNN) is a synchronous servomotor produced by Bosch Rexroth Indramat that complies with the DIN 42955 standard for improved concentricity and runout. It features a 23Nm holding brake that employs an electrical release mechanism. For safe maintenance and repair, it necessitates a 140-minute cooling period. Regular inspections are required to check for any damaged connection cables that need immediate replacement, while imbalances in coupling elements could lead to vibrations. Dust, chips and dirt could negatively affect its performance.
Constructed from materials like brass, copper, aluminum, steel, and other magnetic materials, this three-phase motor can function at up to 55°C. The DIN 6886-1 compliant keyway shaft is equipped with a radial sealing ring resistant to chemicals and oils. The bearings have a mechanical lifespan of 30,000 operating hours, provided the load limits are not exceeded and it is used as specified. The servomotor accommodates gearboxes with oil-proof or closed lubrication systems. However, it can face excessive bearing and shaft load due to radial force from very rigid mountings. Overloading permissible axial force can damage the fixed bearing on the B side. The controller and the brake release function are crucial for operation. An integrated KTY84 temperature sensor is embedded in the stator for monitoring purposes.
