Abstract:
1. An electric generator, comprising: at least a magnet, each having more than two poles; at least a claw-pole set, each being composed of an inner claw-pole and an outer claw-pole; an iron core, connected to each inner claw-pole for enabling loops of the inner claw-poles and the outer claw-poles to be conducted; a solenoid coil, winding on the outside of the iron core; and at least a back panel, each back panel having: an iron back, arranged at a side of the magnet opposite to that proximate to the claw-pole set, for enabling the closing of magnetic lines; a fixation cap, axially arranged at the center of the iron back and the magnet while enabling an end of the fixation cap to abut against the iron core; a bearing, ensheathing the fixation cap; and a bearing cap, wrapping the bearing, wherein the bearing cap is screw-fixed to the iron back by screws, and thus the magnet, the iron back, the bearing, the bearing cap, and the fixation cap are assembled, and wherein, the inner claw-pole and the outer claw-pole are interlaced arranged and used for guiding magnetic flux.
