PROBLEM TO BE SOLVED: To provide a rotary discoid generator employing permanent magnets and a coil.SOLUTION: The rotary discoid generator includes: an annular body 11 of which the inside is punched out in a disk shape partially or entirely; and a disk body 12 which enters a disk-shaped cavity inside the annular body while keeping a fixed gap from an inner peripheral surface of the annular body 11. A plurality of permanent magnets 14 are disposed and fixed within the annular body 11. The permanent magnet 14 is disposed in such a manner that one magnetic pole (defined as a pole A) opposes an outer peripheral surface of the disk body 12. A plurality of permanent magnets 13 are disposed and fixed within the disk body 12. The permanent magnet 13 is disposed in such a manner that one magnetic pole (defined as a pole B) opposes the inner peripheral surface of the annular body. The pole A and the pole B are reversed poles and between the poles A and B, a coil 15 is disposed around which a lead wire is wound. An axial direction of the coil 15 is a radial direction and the annular body 11 or the disk body 12 are rotated with respect to the disk body 12 or the annular body 11, such that power is generated by generating an induction voltage in the coil 15. |
