ABSTRACT:
A claw-pole electric generator has a circumferentially arranged permanent magnet, a ring-shaped coil, a yoke and a cover member. The yoke surrounds an external periphery of the coil. The yoke has a stator yoke portion and a core yoke portion. The stator yoke portion is disposed between the coil and the permanent magnet. The core yoke portion is magnetically linked to the stator yoke portion. The core yoke is disposed on the external periphery of the coil. The coil and the yoke are rotatably disposed in relation to the permanent magnet. The stator yoke portion includes a plurality of first and second yoke sections having a plurality of plate-shaped pieces in a stacked arrangement on opposite sides of the coil in an axial direction. The cover member covers at least part of an external peripheral surface of the yoke section.
