Abstract
Description
Claims (3)
- 전기적 에너지를 하나 또는 다수 플라이휠의 회전 운동에너지의 형태로 저장하는 플라이휠 에너지 저장장치에 있어서, 상기 에너지 저장장치는 플라이휠(21)을 설치 지지하는 회전축(22)이 중력방향에 수직방향인 수평축으로 이루어지며, 상기 수평 회전축(22)은 회전자에 일정한 하중이 작용할 경우에 강한 부상력을 발휘하도록 고온초전도 선재로 형성된 고온초전도자석을 회전축의 저어널로 하여 이루어진 고온초전도 자석저어널과; 상기한 고온초전도 자석저어널에 대향하여 자속고정에 의해 회전체에 작용하는 중력 등의 힘을 자기압력(magnetic pressure)으로 상쇄시켜 부상력을 제공하도록 하는 반원통형으로서 다수의 고온초전도체로 이루어진 고정자를 구비한 고온초전도 저어널 베어링(23)에 의하여 회전체의 하중을 지탱하도록 구성됨을 특징으로 하는 고온초전도 베어링을 이용한 수평축 플라이휠 에너지 저장장치.
- 제1항에 있어서, 상기 회전체는 플라이휠에 직접적으로 부착시키지 않고 베어링 부분과 상기 플라이휘일을 축으로만 연결시켜 플라이휠 형상을 다양하게 변형 가능하도록 함을 특징으로 하는 고온 초전도 베어링을 이용한 수평축 플라이휠 에너지 저장장치.
- 제1항에 있어서, 상기 수평 회전축에는 다수의 플라이휠과 고온초전도 저어널베어링을 직렬 연결하여 회전체의 회전 관성을 증가시켜 대용량화하도록 함을 특징으로 하는 고온초전도 베어링을 이용한 수평축 플라이휠 에너지 저장장치.
