Description

Technical Field

[0002] The automobile generator is the main power source of the automobile. Its function is to supply power to all electrical equipment (except the starter) and charge the battery when the engine is running normally. On the basis of the three-phase stator winding of the ordinary AC generator, the number of winding turns is increased and the terminal is led out, and a set of three-phase bridge rectifier is added. At low speed, the output is connected in series by the original winding and the increased winding. Automobile generators can be divided into DC generators and AC generators. When the external circuit energizes the excitation winding through the brush, a magnetic field is generated, and the claw poles are magnetized into N poles and S poles. When the rotor rotates, the magnetic flux changes alternately in the stator winding. According to the principle of electromagnetic induction, an alternating induced electromotive force is generated in the three-phase winding of the stator. This is the power generation principle of the AC generator.

[0003] The waterproof sealing device mainly covers and wraps the outer surface of the automobile generator. The waterproof device is coated with waterproof paint and has good waterproof performance. The rubber sealing ring provided can seal it to prevent external moisture from penetrating into the waterproof shell. However, the automobile generator will gradually loosen during long-term use. Therefore, the interior of the device is not stable enough, and the installation of the device and the generator is not convenient enough. Therefore, an automobile generator with a waterproof sealing device is designed. Utility Model Content
