Abstract
The invention discloses a power generating device. The power generating device comprises an engine and a generator. An output shaft of the engine is connected with a rotor shaft of the generator through a flexible coupling. The generator comprises the rotor shaft, iron cores and permanent magnets. The iron cores are composed of multiple stampings in an overlapping mode. An axle hole and mounting holes of the permanent magnets are arranged in the central sections of the stampings. The permanent magnets can be directly inserted into the iron cores on the rotor shaft composed of the stampings and therefore the quick and convenient installation can be achieved. More of the corner magnetic line of force of the permanent magnets can pass through the iron cores in a more even manner through communicated grooves. The boundary lines of the adjacent magnetic fields can be made clearer due to heat emission holes and concave grooves.
