The Bosch Rexroth R911255294 (MDD093A-N-040-N2M-110PB1) is a globally recognized motion control AC servo motor offering consistent reliability, superior performance, and durability. Notably lightweight at 13 kilos, it delivers high rotation speeds up to 4000 revolutions per minute. It boasts low radio frequency interference and produces a consistent torque of 9.2 Nm with a 23.3 A cooling current during standby. Additional features include an N-class balance, 110 mm centering diameter, output shaft with keyway, and power connection on the B side. It also has a 0.36 winding resistance and 0.39 torque constant at 20 degrees Celsius. Success in operation requires strategic positioning in a machine, often coupled with a drive controller. Its holding brake produces 11 Nm of torque, with the entire motor meeting IP65 standards for dust and liquid resistance and a 40-micron coated surface for corrosion prevention. It features a maximum torque output of 28.6 Nm, 104.6 A current consumption, digital servo feedback, and an integrated multiturn encoder to precisely manage rotor speed and positioning.
