The R911274745 (KDA 3.3-150-3-AYI-W1) Main Spindle Drive by Rexroth Indramat is specifically engineered to manage and control various parameters of the 2AD asynchronous motor and the 1MB frameless spindle motor, ranging from speed and position to power and torque output. This 22-kilowatt powerhouse operates with impressive rigidity and empowers attached industrial motors to function over a wide speed spectrum, making it optimal for highly specialized industrial equipment such as numerically controlled, printing, and packaging machines. Thanks to its feedback loop control system, the R911274745 (KDA 3.3-150-3-AYI-W1) can autonomously rectify any motor deviations from the set operational specs. This drive supports remarkable resolution, controlling servo motors efficiently even at extremely low rotation speeds. However, it delivers its best performance when operating in ambient temperatures of +5 to +45 degrees Celsius. With a rated current of 150 Amps and a 300-volt DC bus voltage, this main spindle drive marries efficiency and technological sophistication.
