Abstract

The stator assembly comprises a stator iron core, a stator winding and a leading-out wire assembly, the stator winding is arranged on the stator iron core, and the stator winding is provided with m * n leading-out ends; the leading-out wire assembly is arranged on one side of the stator winding in the axial direction of the stator core, the leading-out wire assembly comprises an insulating supporting piece and m * n wire bodies, the m * n wire bodies are electrically connected with the m * n leading-out ends in a one-to-one correspondence mode, a plurality of wire passing channels are formed in the insulating supporting piece, a wire body is arranged in each wire passing channel, and the wire bodies of different phases are arranged at intervals. According to the stator assembly provided by the invention, the function failure of the stator assembly caused by mutual contact of wire bodies of different phases can be avoided; moreover, the processing is easy, the material and processing cost can be saved, and the batch production is also convenient; in addition, the stator assembly is compact in structure and small in radial occupied space, so that arrangement of the stator assembly in the motor is facilitated.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a motor having the same. Background technique [0002] In the field of motor technology, most of the lead wire connection methods are very complex in structure, which increases the difficulty of processing, leads to high processing costs, wastes more materials, and is not conducive to mass production; moreover, the structure occupies axial and The radial space is relatively large, resulting in a waste of motor space layout; in addition, due to the complex structure, insulation treatment is difficult. Contents of the invention [0003] The invention provides a stator assembly, which has the advantages of good insulation, low cost and small volume. [0004] The present invention provides an electrical machine having a stator assembly as described above. [0005] According to the stator assembly of the embodiment of the present invention, the stator assembly...
