The Bosch Rexroth's R911308686 (MSK030B-0900-NN-S1-UP1-NNNN) belongs to the MSK series of motors. It's designed to function optimally at an ambient temperature range of 0 to 40 degrees Celsius, and elevation up to 1000 meters above sea level. Performance decreases by 20% at 55 degrees Celsius and by 30% at elevations of 3000 meters. Ideally, it should be used within the parameters of class 3K4, with relative humidity between 5 and 95% and absolute air humidity ranging from 1 to 29 grams per cubic meter, with a maximum temperature change rate of 0.5 degrees Celsius per minute. Its housing boasts an IP65 rating, upgradeable to IP67 via a sealing air kit. The motor, which is seawater, sewage, mineral oils, and acid-resistant, employs natural convection cooling, features a singleturn optical encoder with 128 signal periods, has a keyway shaft with a sealing ring, and an integrated 1 Nm electrically releasing brake. Its flange mounting design allows installation with the drive side up or down.
