Wind power generator with internal cooling circuit

A wind power generator with a closed internal cooling circuit, said wind power generator comprising:

• a stator having a laminated core and a winding system which forms winding heads at end faces of the stator;
• a cooling jacket enclosing the stator at least in a region of the laminated core;
• a rotor having a magnet wheel jacket which is embodied as a hollow shaft, and permanent magnets which are disposed on the magnet wheel jacket;
• a support assembly for connecting the magnet wheel jacket at end faces thereof in a rotationally fixed manner to a shaft or shaft stub of a wind power plant;
• a first tube arranged in an interior of the hollow shaft which is the magnet wheel jacket of the rotor, and having a lateral surface area extending at an equidistant clearance from the magnet wheel jacket;
• and
• blowers provided with blower vanes and respectively mounted at end faces of the rotor and attached to opposite ends of the first tube arranged in the interior of the hollow shaft which is the magnet wheel jacket of the rotor.
