R911308968
The R911308968 (MKE118B-024-BG0-KE4) is a four-pole synchronous servo motor manufactured by Bosch Rexroth Indramat, specifically designed for potentially explosive environments. It highlights features like high operational reliability, substantial performance data, and low-maintenance operations. Notably, it generates a maximum torque of 102.0 Nm, operated by a 128-step optical encoder with Singleturn EnDat2.1 mit 2048 increments, ensuring accuracy within ±20 angular seconds. The encoder even enables indirect and absolute position recording within a single mechanical rotation. Additionally, the unbraked motor, weighing approximately 44 kg, includes a plain shaft and sealing ring.
The R911308968 (MKE118B-024-BG0-KE4) has a peak velocity of 4000 RPM, a thermal time constant of 90 minutes, and a component release capacity rated at 10.3 nF. At 68 degrees Fahrenheit, the servo motor operates with a torque constant of 1.50 Nm/A, winding resistance of 7.60 mH, and a constant voltage of 130.0 V/min-1. It functions optimally within a 0 to 40-degree Celsius range with an ingress protection rating of 65. The servomotor also showcases features such as a power connection output direction at the top, a cable input diameter of 13–16 mm, a frame size of 118, a sound pressure level under 75 decibels during operation, and a moment of inertia of 0.01940 kgm2.
