Document Type and Number:
Japanese Patent JP2673878
Kind Code:
B2
Abstract:
PURPOSE: To provide the subject device designed to address such instability as to generate magnetic field variation through swinging magnets by making use of e.g. wind power and the device's complication and poor economy due to swinging all the magnets through driving a motor.
CONSTITUTION: This device is so designed that a main magnet device 1 equipped with a magnet subject to axial, rotation by driving a motor and a subordinate magnet device 2 equipped with a magnet subject to rotation around a freely revolving shaft 8 are collocated at such an interval that the magnet of the device 2 rotates around the freely revolving shaft 8 through tuning by the rotation of the magnet of the device 1.
