Title:
SELF ROTATING DYNAMO
Document Type and Number:
Japanese Patent JPS57193963
Kind Code:
A
Abstract:
PURPOSE:To make the rotor of a dynamo capable of rotating on its own without using external force by placing a coil with iron core in a magnetic field and placing another magnet near the iron core so that the iron core is positioned in the middle point of magnetic poles. CONSTITUTION:Rotor magnets 21 and 22, iron cores 31 and 32 round which coils are wound and magnets 41 and 42 which always give magnetic fields to the iron cores are provided. As the rotor magnets 21 and 22 get near the iron cores round which coils are wound, the magnetic fields given to the magnets 41 and 42 are cut and at this time the rotor magnets 21 and 22 are attracted to the direction of rotation by the temporary magnetization of the iron cores due to the influence of the current in the coil. With this arrangement the rotor of a generator can rotate on its own.
