Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a low-noise generator. Background Art

[0002] A generator is a device that converts mechanical energy into electrical energy. It is mainly composed of components such as a rotor, a stator, a winding, and a magnetic field. The rotation of the rotor generates a change in the magnetic field, induces an electric potential in the stator, and outputs electrical energy through the circuit. Generators are widely used in power plants, factories, buildings, ships, vehicles, and other fields. They are often used to provide emergency backup power to generate electricity.

[0003] But the following problems still exist:

[0004] When construction is underway at night, in order to prevent sudden power outages and not affect the progress of construction, generators are generally used to generate electricity to provide lighting for the construction site so that construction can be carried out. However, when the generator is running, it will generate a lot of noise and spread to the surrounding environment, which not only affects the rest of other construction workers around, but also affects the physical health of the construction workers. The ears are easily affected by the noise for a long time, which makes tinnitus easy to occur, and thus there are certain safety hazards.

[0005] Therefore, we propose a low-noise generator to solve the above problems. Utility Model Content
