POWER GENERATOR

PROBLEM TO BE SOLVED: To provide a power generator which can suppress cogging sufficiently without adopting a complex structure.SOLUTION: A power generator 1 comprises: a rotor portion 2 consisting of a plurality of projections 8U, 9, 8L arranged at predetermined pitches in a straight line at positions separated from one another with permanent magnets 7U, 7L sandwiched therebetween; and a stator portion 3 in which a stator member consisting of stator yokes 12U, 12L, permanent magnets 15U, 15L facing the permanent magnet 7U, 7L, and projections 16U, 16U, 16L, 16Lmore projecting to the side of the rotor portion 2 than the permanent magnets 15U, 15L and arranged at predetermined pitches in a straight line at positions separated from one another with the permanent magnets 15U, 15L sandwiched therebetween is disposed with respect to an adjacent stator member thereof such that the two stator members deviate from each other by a half pitch. Not in the side of the stator portion 3, in the side of the rotor portion 2, above described deviation by a half pitch may be realized.
