The invention relates to a cooling system for highly utilized rotating electrical machines, comprising a laminated stator and rotor core consisting of partially laminated cores. The aim of the invention is to provide a cooling system that evacuates the heated cooling medium as fast as possible from the machine, ensures a constant temperature distribution and prevents additional heating of the machine bearings. To achieve said aim, the laminated stator core (1) and laminated rotor core (19) respectively comprise several partially laminated cores having the same length. The partially laminated cores are located at a distance from one another by means of guiding devices and spacer segments. Axial inflow channels (2) and axial outflow channels (3) are distributed over the circumference at the back of the laminated stator core (1). The outflow channels (3) have a closed configuration on both sides. The number of the inwardly directed webs of the guiding device and spacer segments (4) corresponds to the number of inflow (2) and outflow channels (3). Partially laminated stator cores having closed channels (7) are in a combined arrangement with partially laminated stator cores having open and closed channels (8) so that each of the closed channel sections continuously form inflow channels (2) and outflow channels (3). With respect to the design of the housing of the cooling system, radial outflow openings (16) are arranged in positions of the partially laminated stator core (1) where the open channels are located. According to the invention, the cooling system can be used for highly utilized rotating electrical machines. |
