Claims (4)

1. Fremgangsmåde til at drive en vindmølle (2), der inkluderer en rotor med mindst en vinge (10), omfattende: at detektere (302) en risiko for isdannelse for den mindst ene vinge (10); og at bevæge (304) den mindst ene vinge (10) til en position for at reducere risikoen for isdannelse; hvor bevægelsestrinnet yderligere omfatter at gire rotoren i alt væsentligt i en solretning; og hvor bevægelsestrinnet omfatter at gire rotoren i alt væsentligt vinkelret på en vindretning; og hvor bevægelsestrinnet yderligere omfatter at pitche den mindst ene vinge (10) omkring 180 grader, således at hver side af den mindst ene vinge (10) modtager en bestemt rum tid vendende mod solen afhængigt af temperaturen, tid på dagen og/eller risikoforhold for isdannelse.
2. Fremgangsmåden ifølge krav 1, hvor bevægelsestrinnet omfatter at pitche den mindst ene vinge (10) til i alt væsentligt nul graders pitch.
3. Vindmølle (2), omfattende: et tårn (4), der bærer en transmission (8) med en gearkasse (12) og en generator (14); et nav (9) anbragt på en ende af transmissionen (8); mindst en vinge (10) anbragt på navet (9) til at rotere transmissionen (8); en sensor (402) til at detektere en risiko for isdannelse for vingen; og hvor et styresystem (16) er driftsbart til at bevæge den mindst ene vinge til en position til at reducere risikoen for isdannelse ved at gire transmissionen (8) i alt væsentligt i en solretning, og hvor styresystemet (16) er driftsbart til at gire transmissionen (8) i alt væsentligt vinkelret på en vindretning og til at pitche den mindst ene vinge (10) omkring 180 grader, således at hver side af den mindst ene vinge (10) modtager en bestemt rum tid vendende mod solen afhængigt af temperaturen, tid på dagen og/eller risikoforhold for isdannelse.
4. Vindmøllen (2) ifølge krav 3, hvor styresystemet (16) er driftsbart til at pitche den mindst ene vinge (10) med i alt væsentligt nul graders pitch.
