Title:
POWER GENERATOR
Document Type and Number:
Japanese Patent JP2017034836
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generator capable of improving an electromotive force while maintaining a low starting torque.SOLUTION: A power generator (1) comprises a housing (11), a shaft (12), a magnet (15), and four air-core coils (16). The shaft (12) is supported by the housing (11) freely rotatably. The magnet (15) is housed in the housing (11) and supported by the shaft (12), and rotates around a rotation axis (O) of the shaft (12), and is magnetized in a rotation direction. The four air-core coils (16) are housed in the housing (11), fixed to the housing (11), arranged so as to be opposed to the magnet (15), and arranged centering around the rotation axis (O) of the shaft (12).SELECTED DRAWING: Figure 1
