ABSTRACT:
An electric generator is disclosed, which comprises: at least a magnet, each having more than two poles; and at least a claw-pole set, each being composed of an inner claw-pole and an outer claw-pole; wherein, the inner claw-pole and the outer claw-pole are interlaced arranged and used for guiding magnetic flux; the inner claw-pole is connected to an iron core whose outer diameter is smaller than the magnet and thus the loop of the inner claw-pole and the outer claw-pole is conducted; the core is winded by a solenoid coil; the number of claws of the inner claw-pole is the half of the pole number of the magnet while the outer claw-pole is the same, so that, as the magnet is move relative to the claw-pole set, the magnetic flux passing through the solenoid coil will change continuously and thus an induction electromotive force is generated.
