Generator (1), især til en vindmølle, omfattende en rotor (2), som er roter-bart monteret i forhold til en stator (3), og et støtteelement (10) til stationær montering af statoren (3), hvor statoren (3) omfatter mindst en not, som er anbragt på en overflade af statoren (3), som er afgrænset af en overflade af støtteelementet (10), således at der dannes mindst en ledning (9) til at lede et kølemiddel, kendetegnet ved, at støtteelementet (10) er hult og omfatter to ringformede endevægge (13), som begrænser et indvendigt rum, hvor hver af endevæggene (13) omfatter en flerhed af åbninger (14), som er anbragt i omkredsen i regelmæssige afstande.
2. Generator (1) ifølge krav 1, kendetegnet ved, at statoren (3) omfatter en flerhed af noter, som er anbragt i regelmæssige afstande omkring en omkreds af statoren (3), således at der dannes en flerhed af ledninger (9) til at lede kølemidlet.
3. Generator (1) ifølge krav 1 eller 2, kendetegnet ved, at den i det mindste ene not strækker sig i en aksial retning defineret af en rotationsakse af rotoren (2) i forhold til statoren (3).
4. Generator (1) ifølge et af de foregående krav, kendetegnet ved, at statoren (3) er samlet af en flerhed af statorsegmenter, hvor hvert statorseg-ment omfatter mindst en not.
5. Generator (1) ifølge et af de foregående krav, kendetegnet ved, at der er anbragt kølefinner i den i det mindste ene ledning (9).
6. Generator (1) ifølge et af de foregående krav, kendetegnet ved, at en yderligere skillevæg (15), der er anbragt mellem endevæggene (13), inddeler det indvendige rum af støttelementet (10) i to kamre, hvor skillevæggen (15) optager mindst en ventilator, således at der frembringes en strøm af et gasformigt kølemiddel inden i det indvendige rum af støtteelementet (10).
7. Generator (1) ifølge krav 6, kendetegnet ved, at den i det mindste ene ventilator er en aksial- eller en centrifugalventilator.
8. Generator (1) ifølge krav 6 eller 7, kendetegnet ved, at et varmevekslermiddel af en væskekølingsindretning er monteret på skillevæggen (15).
9. Vindmølle med en generator (1) ifølge et af de foregående krav.
