Stator assembly and motor

Abstract

The present invention discloses a stator assembly and a motor. The stator assembly comprises a stator iron core, a plurality of square copper wires and a plurality of special-shaped switching metal pieces, the stator iron core is annularly provided with a plurality of wire grooves extending in the axial direction of the stator iron core, and each wire groove is provided with an opening communicating with the two axial ends of the stator iron core; the square copper wires enter the wire grooves through an opening, and the wire grooves are at least provided with the square copper wires in a penetrating manner; the special-shaped switching metal pieces are arranged at the axial end parts of the stator core, and the two opposite ends of each special-shaped switching metal piece are connected to the two square copper wires respectively, so that the plurality of square copper wires are electrically conducted. According to the technical scheme, the slot fullness utilization rate of the stator core is guaranteed, and meanwhile the manufacturing and mounting efficiency of the stator assembly is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a motor using the stator assembly. Background technique [0002] In the related art, the motor stator usually includes a stator core and a thin round copper wire wound in the slot of the stator iron core, but there is a large gap between two adjacent thin round copper wires, resulting in the stator core The utilization rate of the wire slot is low. In order to ensure the full rate of the slot, it can be replaced with a square copper wire with a square cross-sectional area. However, in the stator core of a small motor, there are technical difficulties in the winding process of the square copper wire. It relies heavily on manual operations by workers, resulting in slow installation efficiency. [0003] The above content is only used to assist in understanding the technical solution of the present application, and does not mean that the above content is admitte...
