Title:
POWER GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2017169328
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generation device capable of stably generating high power.SOLUTION: A power generation device comprises a rotating shaft 10, a rotating portion 20 connected to the rotating shaft 10, at least one permanent magnet 30 for generating a magnetic flux, at least one coil 40, and at least one magnetic yoke 50. The magnetic yoke 50 is a closed magnetic path including at least one permanent magnet 30 and at least one coil 40, and forms a closed magnetic path in which a magnetic flux occurring from the permanent magnet 30 and interlinking with the coil 40 returns to the permanent magnet 30. The rotating portion 20 includes at least one opening 21 for changing the magnetic flux occurring from each permanent magnet 30 and interlinking with each coil 40. The rotating portion 20, the permanent magnet 30, the coil 40, and the magnetic yoke 50 are arranged so that the opening 21 crosses the closed magnetic path when the rotating portion 20 rotates around the rotating shaft 10.SELECTED DRAWING: Figure 1
