Rotary energy recovery device based on electromagnetic induction principle

摘要: The invention discloses a rotary energy recovery device based on an electromagnetic induction principle. comprises outer ring component and inner located in the component. are coaxially arranged installed mode that can rotate relative to along axis. A coil is fixed side of component, magnet connected side, close coil, ringin axial direction, when rotates magnetic flux changes generate electric energy. free intermediate mechanical transmission parts, links simplified, loss avoided, structure simple, size small, spatial arrangement easy, be achieved simply effectively through rotating speed difference between ring.
