Problems solved by technology

[0002] In the related art, in the hairpin coils of the same layer used in the plug-in stator assembly, the U-shaped head is bent inwardly towards one of the legs to form a bending step, which will make The end of the U-shaped part of the hairpin coil (that is, the hairpin end) becomes higher; in addition, because the bending fillet of the bending step is too small, it is easy to damage the paint on the surface of the flat copper wire, resulting in poor insulation

Abstract

The invention discloses a stator assembly and a same-layer conductor section thereof and a motor. The same-layer conductor sections are adapted to be inserted into the same slot layers of different stator slots of the stator core; each same-layer conductor section is formed in a general I-shaped shape and comprises a bending part, a first groove inner part and a second groove inner part, wherein the bending part comprises a first layer section, a second layer section, and a connecting section connected between the first layer section and the second layer section; one of the first layer sectionand the second layer section one is radially twisted relative to the connecting section; the first groove inner part is connected with one end, far from the connecting section, of the first layer section; and the second groove inner part is connected with one end, far from the connecting section, of the second layer section. According to the same-layer conductor section provided by the embodiments of the invention, the structure of the stator winding is compact, and the insulation effect is good.

Description

technical field [0001] The invention relates to the field of motors, in particular to a conductor segment of a stator assembly, a stator assembly including the conductor segment, and a motor including the stator assembly. Background technique [0002] In the related art, in the hairpin coils of the same layer used in the plug-in stator assembly, the U-shaped head is bent inwardly towards one of the legs to form a bending step, which will make The end of the U-shaped part of the hairpin coil (that is, the hairpin end) becomes higher; in addition, because the bending fillet of the bending step is too small, it is easy to damage the paint skin on the surface of the flat copper wire, resulting in poor insulation. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the invention proposes a conductor segment of a stator assembly, which leads to a compact structure of the stator win...
