Problems solved by technology

At present, most of the mass-produced generators in the domestic automobile industry use the stator assembly of enamelled round copper wire. The automatic production technology of this structure is basically mature, but the round copper wire has a low slot full rate and long and irregular end windings, which make the power generation The problems of high copper consumption, poor cooling effect and high noise

Abstract

The invention relates to an automobile generator stator assembly employing a three-phase multi-slot flat copper wire. The automobile generator stator assembly comprises a stator core and three phase windings A, B and C, wherein the automobile generator stator assembly is characterized in that inner and outer two layers of winding positions are arranged in each winding slot of the stator core; the three phase windings A, B and C are alternately arranged in the stator core; each phase winding comprises two split-phase windings which are adjacent in circumferential direction; each split-phase winding comprises a layered winding I and a layered winding II, which are adjacent in radial direction in the same slot and are opposite in direction and are arranged in a wave form; the layered windings I of the two split-phase windings are parallel in winding direction; and the layered windings II of the two split-phase windings are parallel in winding direction. The wire inserting design of the structure significantly improves the copper wire spacer factor of the stator assembly; the usage amount of the copper wire at the end part of the stator assembly is reduced; the material cost is reduced; meanwhile, the volume of a generator is reduced; the power density of the generator is improved; the copper loss is reduced; and the generator efficiency is improved.

Description

technical field [0001] The invention relates to a three-phase multi-slot flat copper wire automobile generator stator assembly. Background technique [0002] The stator assembly of the automobile generator is a very important electromagnetic component in the generator. Whether its design is reasonable or not directly affects the comprehensive technical indicators such as the performance, efficiency, heat generation and noise of the generator. At present, most of the mass-produced generators in the domestic automobile industry use the stator assembly of enamelled round copper wire. The automatic production technology of this structure is basically mature, but the round copper wire has a low slot full rate and long and irregular end windings, which make the power generation The problems of high copper consumption, poor cooling effect and high noise. Contents of the invention [0003] The purpose of the present invention is to provide a three-phase multi-slot flat copper wir...
