[0002] A generator is a device that converts mechanical energy into electrical energy. It is usually composed of a generator casing, rotor, stator, brushes and other components. Its working principle is to generate induced electromotive force by the rotation of the rotor in a magnetic field, thereby realizing the conversion of electrical energy. The casing of the generator usually plays the role of protecting internal equipment, isolating the external environment and dissipating heat. In order to ensure the normal operation of the generator and extend its service life, regular maintenance is required. Rust removal of the generator casing is a very important maintenance work, which can extend the service life of the equipment and ensure its normal operation.
