Title:
振動発電機
Document Type and Number:
Japanese Patent JP5921005
Kind Code:
B2
Abstract:
Provided is a vibration power generator configured to enhance an electromotive force generated through relative movement of a permanent magnet and a coil. The vibration power generator includes: a plurality of permanent magnets (1, 2) integrated together to have given inter-magnet gaps under a state in which the same poles of the permanent magnets are opposed to each other; and a plurality of coils (3, 4) arranged on respective outer peripheries of the plurality of permanent magnets so as to have a distance from the plurality of permanent magnets, and is configured to generate an electric power through relative movement of the plurality of permanent magnets and the plurality of coils. A relationship between a length of the opposed coils and a length of the permanent magnet is set so that the length of the coils is larger than the length of the permanent magnet and equal to or smaller than a sum of the length of the permanent magnet and a length of the inter-magnet gap.
