Title:
ELECTRIC POWER GENERATING DEVICE BY VIBRATION
Document Type and Number:
Japanese Patent JPS57193961
Kind Code:
A
Abstract:
PURPOSE:To obtain electro-motive force by means of making unnecessary to bear the rotating section with simple construction and without restriction for the place of installation by vibrating a magnetic pole that generates magnetic field by means of a vibrator and obtaining electro-motive force by means of changing the number of magnetic fluxes that cross the armature coil. CONSTITUTION:The iron core 2 of a stator that is cylindrical is installed projecting on a base plate 1, and many throttles 3 are pierced through the inner side of the iron core 2, and an armature coil 4 that is continuously lap winding and soon is put on the core and the inside face of the iron core 2 is covered with a cushioning material 5 such as rubber, and at the radial and symmetrical positions of the circumferential face a hole 8 is pierced at the central position of the upper face of a swinging piece 7 made of a permanent magnet consisting of N and S poles and so on, and the swinging piece 7 is inserted into the iron core 2 and the latter is supported by a spring 9. A bearing 10 is fastened tightly on the upper end of the hole 8 of the swinging piece 7 to support a rotating shaft 11, and at the lower end of the rotating shaft 11 an eccentric plate 12 for generating vibration is also installed to constitute an electric power generating device by vibration.
