R911299891
The product is Bosch Rexroth's IndraDyn S servo motor, R911299891 (MSK070C-0450-NN-M2-UP1-RNNN), which forms part of their advanced IndraDrive drive system. This compact, powerful motor falls under the MSK series and stands out for its high dynamics, high torque density, and versatility. It significantly exceeds the standard performance of regular servo motors. The R911299891 (MSK070C-0450-NN-M2-UP1-RNNN) model uses natural convection to cool itself, effectively transferring heat from operation to the surrounding air and machine body.
The R911299891 (MSK070C-0450-NN-M2-UP1-RNNN) servo motor employs a multiturn absolute optical encoder with an EnDat 2.1 interface to allow the drive controller to monitor rotor position, which is crucial for speed and position control. The motor’s shaft is designed with a DIN 6885-1 compliant keyway and a shaft sealing ring. An electrically-released holding brake provides 23Nm of torque. With 6 pole pairs, the motor achieves a maximum torque of 33Nm and has a rotor with a moment of inertia of 0.00291 kgm2. The motor is rated IP 65 according to IEC 60529, ensuring that it can withstand dust, solid objects, and water jets. The exterior housing boasts a durable black 2K epoxy resin coating (RAL9005), resistant to dilute acids/alkaline solutions, seawater, sewage, and current mineral oils.
