Cooling arrangement for the rotor of an electric machine
The invention discloses a cooling arrangement for the rotor of an electric machine with longitudinal slots having disposed therein exciter winding sections which must be cooled to a low temperature, the arrangement having a feed and discharge line, in which a multiplicity of individual cooling canals running in the circumferential direction and a multiplicity of individual radial coolant feed lines and/or discharge lines are provided for each winding section over its axial length so that the cooling arrangement can be optimized with regard to the thermodynamic pressure losses of the coolant, its temperature rise and the heat transfer conditions while at the same time achieving a favorable space factor of the conductor material within the slots.
