Claims (11)

1. Elektrisk maskine med en stator (1), der omfatter en statorlaminering (2), der i det mindste delvist omslutter flere statorviklinger (3), en rotor (14) og et kølemiddel, i hvilket et gasformigt kølemedium cirkulerer, kendetegnet ved, at den indre stator (1) omfatter kølemidlet, hvor kølemidlet er en lukket kølekanal (4), der er anbragt radialt inden i statorlamineringen (2) og er udformet langs hele omkredslængden af statorlamineringen (2), og statorlamineringen (2) i det mindste delvist er udformet som finner (5), der rager radialt indad fra statoren ind i kølekanalen, som fungerer som et optagelsesmiddel for finnerne.
2. Elektrisk maskine ifølge krav 1, hvor finnerne (5) er anbragt langs omkredsen i aksial retning på en ringlignende måde.
3. Elektrisk maskine ifølge et af de foregående krav, hvor kølekanalen (4) er udstrakt aksialt for at omfatte statorviklingernes ender (3).
4. Elektrisk maskine ifølge krav 3, hvor gascirkulationsmidler (12), som tilvejebringer gascirkulation gennem statorviklingernes ender (3), er anbragt inden i de aksialt udstrakte dele af kølekanalen (4), hvilket giver det gasformige kølemedium mulighed for at cirkulere igennem statorviklingernes ender (3).
5. Elektrisk maskine ifølge et af de foregående krav, hvor mindst en indvendig varmeveksler (6) er anbragt inden i kølekanalen (4).
6. Elektrisk maskine ifølge krav 5, hvor mindst en ventilator (7) er knyttet til den indvendige varmeveksler (6).
7. Elektrisk maskine ifølge krav 5 eller 6, hvor den indvendige varmeveksler (6) er forbundet termisk med en udvendig varmeveksler (10).
8. Elektrisk maskine ifølge krav 7, hvor den udvendige varmeveksler (10) er en passiv køler.
9. Elektrisk maskine ifølge et af kravene 5, 6 eller 7, hvor den indvendige varmeveksler (6) er en vand-/luftvarmeveksler.
10. Elektrisk maskine ifølge et af de foregående krav, hvor rotoren (14) er anbragt uden for statoren (1).
11. Elektrisk maskine ifølge et af de foregående krav, hvor det gasformige kølemedium er luft.
