PROBLEM TO BE SOLVED: To provide a power generator capable of generating power supplied to a battery with higher power generation efficiency.SOLUTION: A power generator comprises: a rotor 33 having a first permanent magnet 36 and a second permanent magnet 37 in a rotation direction of a rotation axis 32; a stator 35 surrounding an outer periphery of the rotor 33; a first field coil 41 which is positioned in a position confronting the first permanent magnet 36 and in which driving current flows around the rotation axis 32; a second field coil 51 which is positioned in a position confronting the second permanent magnet 37 and in which driving current flows in the same direction as the first field coil 41 around the rotation axis 32; and a control circuit for controlling the driving current of the first field coil 41 and the driving current of the second field coil 51. A positive electrode is set toward the stator 35 in the first permanent magnet 36, and it is positioned closer to the first field coil 41, and a negative electrode is set toward the stator 35 in the second permanent magnet 37, and it is positioned closer to the second field coil 51.SELECTED DRAWING: Figure 2 【課題】バッテリーに供給する電力をより高い発電効率のもとで発電することができる発電装置を提供する。【解決手段】発電装置は、回転軸３２の回転方向に第１永久磁石３６と第２永久磁石３７とを有するロータ３３と、ロータ３３の外周部を取り囲むステータ３５と、第１永久磁石３６に対向する位置に位置して回転軸３２周りに駆動電流が流れる第１界磁コイル４１と、第２永久磁石３７に対向する位置に位置して回転軸３２周りに第１界磁コイル４１と同じ方向に駆動電流が流れる第２界磁コイル５１と、第１界磁コイル４１の駆動電流および第２界磁コイル５１の駆動電流を制御する制御回路と、を備え、第１永久磁石３６はステータ３５に向けて正極が設定されて第１界磁コイル４１寄りに位置し、第２永久磁石３７はステータ３５に向けて負極が設定されて第２界磁コイル５１寄りに位置している。【選択図】図２
