The Bosch Rexroth rotor system MPN R911246972 (1MR312B-A060) is engineered for integration within stators of 'B' frame length and motor size 312. It employs liquid cooling operating with a 3 bar pressure capacity, dissipating approximately one-third of the total generated heat. The rotor should be operated with coolant temperatures maintained between 10°C and 40°C. Installing flow, pressure, and temperature controls is recommended to prevent excessive temperature gradients and avoid operational failure. Coolant entry temperature must not fall below ambient to prevent condensation. The rotor is designed for use in environments from 0°C to 40°C, has insulation class F, and is rated for installation at altitudes up to 1000 meters.
