POWER GENERATION SYSTEM IN LINEAR MOTION DEVICE

PROBLEM TO BE SOLVED: To provide technology for efficiently achieving continuous power generation with relative movement in a linear motion device.SOLUTION: In a power generation system, a linear motion device comprises a track member having a metallic surface section and a moving member. A rotary magnet section is arranged on the moving member so that a rotary axis of the rotary magnet section having a plurality of permanent magnets crosses a longitudinal direction of the track member at a prescribed angle, a part of a rotary peripheral face of the rotary magnet section faces the surface section and a distance between a part of the rotary peripheral face and the surface section becomes a prescribed distance for generating eddy current on the surface section by relative movement of the moving member to the track member. A coil member is disposed in proximity to the rotary magnet section rotating with the relative movement of the moving member to the track member, and power is generated by a change in magnetic flux passing the coil member with rotation of the rotary magnet section.SELECTED DRAWING: Figure 3 【課題】直動装置において、効率的に、その相対移動に伴って連続的な発電を可能とする技術を提供する。【解決手段】金属製の表面部を有する軌道部材と、移動部材と、を有する直動装置における発電システムであって、複数の永久磁石を有する回転磁石部の回転軸が、軌道部材の長手方向に対して所定角度で交差するように、且つ、該回転磁石部の回転周面の一部が表面部と対向し且つ該回転周面の一部と該表面部との距離が、該移動部材の該軌道部材に対する相対移動によって該表面部に渦電流を生成する所定距離となるように、該回転磁石部が移動部材上に配置される。そして、移動部材の軌道部材に対する相対移動に伴って回転する回転磁石部に近接してコイル部材を配置し、該回転磁石部の回転により該コイル部材を通過する磁束変化により発電が行われる。【選択図】図３
