R911247901
The R911247901 (MDD112B-N-040-N2L-130GA0) is an AC servomotor, produced by Bosch Rexroth Indramat, known for its high dynamic performance and precision. This motor operates optimally when stringent synchronism is required as it delivers high contouring accuracy at superior feed rates. Its operating mechanism is driven by permanent magnets, and its brushless design enhances its durability. With a nominal speed of 4,000min-1, the motor also incorporates both fixed and floating bearings. Among its notable features is the B5-design flange with through-holes for easy mounting. The motor is designed with an unkeyed shaft and has a size code of 112. The motor operates efficiently in ambient temperatures ranging from 0°C to 45°C.
Uniquely, the R911247901 (MDD112B-N-040-N2L-130GA0) can withstand harsh environmental conditions thanks to the robust housing which meets the DIN 40 050 specification. Its sturdy black prime coating also enhances its durability. The motor, which weighs 25 kg (excluding the blower), is designed to prevent liquid intrusion through the output shaft. The motor uses a combination of axial and radial surface cooling. The motor features multiple connection points, including a power cable, temperature sensor connecting cable, and a 12-pin flanged socket for the feedback connection. In instances where the motor is stored for more than two years, reseating is necessary. The servomotor is supplied in specialized, military-grade packaging to minimize damage during transportation.
