Claims (3)
- 대형 프로펠러(20)가 설치되고, 상기 프로펠러(20)의 축에 발전기(30)가 결합된 풍력발전기에 있어서,상기 대형 프로펠러(20) 각각의 회전날개(22) 일측에는 영구자석(24)을 부착하되, 상기 영구자석(24)은 횡방향 양측 끝단에 각각 선단 영구자석(24)과 후단 영구자석(24a)이 설치되며,상기 대형 프로펠러(20)의 배면측에는 작은 크기의 소형 프로펠러(50)를 설치하되, 상기 소형 프로펠러(50)의 몸체에는 조정기를 구비하며,상기 회전날개(22)와 이격되어 원형의 고정대(40)가 구비되며, 상기 고정대(40)에는 전자석(44)이 다수 부착되며,상기 조정기는 회전날개(22)가 회전하여 회전날개(22)의 영구자석(24)이 고정대(40)의 전자석(44) 측에 가까워지면 고정대(40)의 전자석(44)에 전류를 공급하여 전자석(44)에 발생하는 자기장에 의해 회전날개(22)를 잡아당겨 회전력을 보강하고, 상기 회전날개(22)의 영구자석(24)이 고정대(40)의 전자석(44)을 지나는 순간 전류를 단전시켜 회전날개(22)의 회전력이 그대로 유지되도록 하는 것을 특징으로 하는 자력을 이용한 풍력발전기.
