Problems solved by technology

[0003] In the prior art, the stator assembly includes a stator core and a stator winding. Taking the stator winding as an example, the stator winding is made of enamelled round copper wire, which makes the slot fill rate of the stator core relatively low, and the copper consumption of the manufactured motor is relatively high.

Abstract

The invention provides a stator assembly and a driving motor, and relates to the technical field of motors. The stator assembly comprises three-phase windings and a stator iron core with multiple wiring ducts; the three-phase windings are alternatively arranged on the stator iron core along a circumference of the stator iron; and each phase winding comprises multi-group of winding basic elements made of flat copper wires, two groups of cross-wire connecting elements, a group of phase leading-out terminal element and a group of phase wire-tying terminal element; multiple groups of winding basicelements form six open-loop first branch windings; two groups of cross-wire connecting elements connect the six branch windings as two paths of second branch windings; each phase comprises two pathsof second branch windings, one end of each second branch winding is connected with the corresponding phase leading-out terminal element, and the other end is connected with the corresponding phase wire-tying terminal element; and the various groups of phase wire-tying terminal elements are mutually connected. The stator assembly and the driving motor relieve the problems that the slot filling factor of the stator iron core is comparatively slow, and the manufactured motor is comparatively high in copper consumption ratio since the stator winding adopts enameled round copper wires.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a driving motor. Background technique [0002] The stator assembly is an important part of the motor, and whether its structure is perfect is directly related to the performance of the motor. [0003] In the prior art, the stator assembly includes a stator core and a stator winding. Taking the stator winding as an example, the stator winding is made of enamelled round copper wire, which makes the slot fill rate of the stator core relatively low, and the copper consumption of the manufactured motor is relatively high. . [0004] Therefore, it is urgent to design a new stator assembly to improve the above problems. Contents of the invention [0005] The first purpose of the present invention is to provide a stator assembly to alleviate the problem of using enamelled round copper wires for the stator windings in the prior art, so that the slot fill ratio of ...
