WIND POWER GENERATION SYSTEM, ARRANGEMENT CONFIGURATION OF PERMANENT MAGNET AND ELECTRICITY-FORCE CONVERSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a wind power generation system efficiently generating electric power without stop of rotation of an impeller even in a breeze.

SOLUTION: The wind power generation system 10 comprises a frame, the impeller 12 rotatably supported by the frame, a plurality of permanent magnets 31 provided on the impeller 12 and arranged at equal distances from its rotation center, and a coil group 32 provided on the frame and annularly arranged. The permanent magnets 31 and the coil group 32 are close to each other and move relatively and the coil group 32 generates electric power under the action reverse to a linear motor. The coil group 32 is attached to a ring provided on the frame and the permanent magnets 31 are provided on lower ends of vertical blades 26 of the impeller.
