Background

The generator is composed of a stator, a rotor and a shell, wherein the stator mainly comprises silicon steel sheets, coils and other parts and is fixedly assembled on the fixed disc. The rotor mainly comprises a rotating shaft, a magnet and the like. When external force acts on the rotating shaft, the coil cuts the magnetic field in rotation, so that the coil generates electric energy. Most of the current generators are of a single stator and rotor structure. For some places with large external force, such as wind power generators in high wind areas, the generator with larger power can be driven. However, the generator with a single stator and rotor can only generate a single set value, and it is difficult to improve the efficiency of the generator. In addition, the generator generally utilizes the air holes on the housing to dissipate heat naturally, which causes the heat energy generated during the operation of the generator to be difficult to dissipate. The poor radiating effect can lead to the generator efficiency to reduce, influence life's problem.
