Method for embedding flat copper wire by using split stator core

Abstract

The invention discloses a method for embedding a flat copper wire by using a split stator core. The method comprises the following steps of: bending and forming the flat copper wire to form a hairpintype flat copper wire; sequentially inserting the welding ends of a plurality of hairpin type flat copper wires into the wire inserting holes of the base tool; arranging a winding on a base tool whileinserting tool sectioning structures into the arranged winding, and completing pre-arrangement of the winding when a plurality of tool sectioning structures are spliced into a full-circle tool sectioning above the base tool; inserting all the stator sectioning structures into a pre-arranged winding according to a mode of taking down one tool sectioning structure and then inserting one stator sectioning structure, and splicing the stator sectioning structures into a whole-circle stator sectioning of an embedded wire after the stator sectioning structures are inserted into the pre-arranged winding. According to the invention, the winding is inserted into the stator iron core after the whole forming process is completed, so that the flat copper wire is prevented from being formed in the stator iron core, the possibility of short circuit between the stator iron core and the winding is reduced, the percent of pass of the coil inserting stator can be improved, and the material cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a method for embedding flat copper wires by using a split stator core. Background technique [0002] At present, the flat copper wire embedded stator generally adopts the form of inserting from above along the cross section of the iron core punching sheet, and the inserted flat copper wire is subjected to other processes such as forming of the winding welding end. At present, this method needs to continue the forming process after the core and winding are assembled, so it may cause mutual movement between the winding and the iron core in the subsequent forming process. Once the movement exceeds the expected value, it is easy to cause winding damage. A short circuit caused by interference with the iron core. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for embedding flat copper wires using split...
