Stator assembly with high power generation performance

Abstract

The invention relates to a stator assembly with high power generation performance, comprising a stator core; a plurality of wire slots are circumferentially arranged in the stator core three layers ofwinding sets are inserted into the plurality of wire slots, the three layers of winding sets are formed by connecting an even-number group of copper wire winding sets, each copper wire winding set iscomposed of an outer-ring copper wire winding set, a middle-ring copper wire winding set and an inner-ring copper wire winding set, the inner-ring copper wire winding set, the middle-ring copper wirewinding set and the inner-ring copper wire winding set are respectively composed of a plurality of bent flat copper wires with different numbers, the bottoms of the plurality of flat copper wires ofthe outer-ring copper wire winding set, the middle-ring copper wire winding set and the inner-ring copper wire winding set are sequentially welded and combined, the bottom of one flat copper wire of the outer-ring copper wire winding set is welded with the bottom of an input wire inserted into the wire slot, the bottom of one flat copper wire of the inner-ring copper wire winding set is welded with the bottom of an output wire inserted in the wire slot, the top ends of the input lines of the even-numbered group of copper wire winding sets form a group in pairs and are welded together, and thetop ends of the output lines of the even-numbered group of copper wire winding sets form a group in pairs and are welded together.

Description

technical field [0001] The invention relates to a generator stator, in particular to a stator assembly with high power generation performance. Background technique [0002] The stator is an important part of the automobile generator. It is composed of a stator core and a stator winding. The wires of the stator winding are embedded in the wire groove of the stator core. At present, most stator windings are composed of two-layer winding groups, but the stator with two-layer winding groups has poor power generation performance. Although there are stators with three-layer winding groups on the market, the winding process efficiency is low and time-consuming. The three-layer windings are formed by directly winding multiple round copper wires, and finally the heads of the multiple copper wires are welded together. , it takes a long time to complete the winding of a stator, and the use of round copper wires will cause the problem of low stator slot fullness, which will also cause ...
