R911254847
The Bosch Rexroth Indramat R911254847 (MDD090B-N-030-N2L-110PA0) is an AC servo motor designed with a sensor, commonly referred to as an encoder, for speed and position measurements. The motor operates on a closed-loop control system, with the encoder transmitting these readings through a feedback cable to a controller for output adjustments. The motor's rated speed is set at 3000 RPM and it is naturally cooled through convection with a continuous torque and current at 7.2 Nm and 12.6 Amps respectively when at standstill. A cooling fan can be installed for surface cooling, raising the continuous torque and current to 10.5 Nm and 18.4 Amps respectively.
The servo motor's construction prioritizes durability, with the housing and power and feedback connectors fully sealed to achieve IP65 ingress protection. This ensures the motor is dustproof and protected against low-pressure water jets, though care should be taken to guard it from accumulated water when mounted with an upward-facing shaft. The R911254847 (MDD090B-N-030-N2L-110PA0) model is fitted with an output shaft that features a keyway and a power connection on side A of the housing. The motor has a centering diameter of 110mm and an approximate shipping weight of 18kg. It conforms to insulation class F and sports a prime black coat for added protection.
