Description
)中の流速は、通常、同じ大きさであるが、10−15m/sまで急速に増加する場合がある。
ードはより明確で安定した位置をとる。さらに、負荷支持構造物が、はるかに単純になるとともに、他の理由のために存在する成分から大部分が成るという事実により、アセンブリ全体の複雑さは軽減される。したがって、本発明のアセンブリは、大きなアセンブリが要求され、流れの条件が常に安定しているわけではない状況において、非常に有利になる。
方にかかる曲げ力により支持されるという事実によって、ブレードが対になって互いに安定するという利点が達成される。
される。したがって、便宜な方法で、発電機は海中環境で作用するように適合される。
E=−N・dφ/dt
の関係からファラデーの法則に従って決定される。式中、Nは巻線の数であり、φは電磁流量である。このことは、ゆっくり動いている回転子では、dφ/dtが小さくなり、結果として誘導される起電力は小さくなることを意味している。固定子も回転し、その回転方向が回転子の回転とは反対方向である事実により、回転子と固定子の間の相対運動はそれらの回転速度の合計になるだろう。このため、dφ/dtの項はそれに対応して増大する。したがって、固定子が回転子と同じ速度で回転する場合、dφ/dtの項は2倍になり、静止している固定子と比較して、誘導される起電力は2倍になる。
