Abstract

The invention provides an automobile electric generator structure applied to the field of automobile parts. The automobile electric generator structure capable of reducing noise comprises a rotor and a stator, wherein the stator comprises a stator iron core (2) installed inside an electric generator shell (1); an anti-vibration pad I (7) is arranged between a front end cover (3) of the electric generator shell (1) and the stator iron core (2); an anti-vibration pad II (8) is arranged between a rear end cover (4) of the electric generator shell (1) and the stator iron core (2); the front end cover (3) and the rear end cover (4) are connected together through a plurality of fastening and penetrating bolts (5). The automobile electric generator structure can largely reduce pulse generated when electromagnetic force acts on a magnet yoke of the stator iron core, weaken the resonance generated when the inherent frequency of the stator iron core is close to the frequency of radial electromagnetic force wave, achieve the purpose of isolating the stator iron core from generating resonance wave, and reduce noise generated by the stator iron core, thereby reducing the noise of an automobile electric generator and improving the overall quality of the electric generator structure.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and more specifically relates to a vehicle generator structure capable of reducing noise. Background technique [0002] Automotive alternators have been widely used in high-end cars. The noise problem is a factor that affects the comfort of a car. The noise generated by the vehicle alternator is an integral part of the vehicle noise. Therefore, solving the noise problem of automotive alternators is a user requirement. From the noise mechanism of the vehicle alternator: electromagnetic noise, mechanical noise, air noise. For the generator, since the air gap magnetic wave acts on the teeth of the stator core, radial and tangential electromagnetic forces are generated. The radial electromagnetic force makes the stator core yoke stretch and deform, which makes the air pulsation cause noise—this is the main source of noise, and the tangential electromagnetic force makes the stator core teeth be...
