Stator, motor, compressor, vehicle and manufacturing method of stator

Abstract

The invention provides a stator, a motor, a compressor, a vehicle and a manufacturing method of the stator, and the stator comprises a stator core which comprises a tooth part and a yoke part which are connected with each other; and the stator also comprises a stator winding wound on the tooth part. The stator core is provided with a fracture, an overlapping gap is formed on the first side of the fracture of the stator core, an overlapping part is formed on the second side of the fracture of the stator core, the height of the part, firstly inserted into the overlapping gap, of the overlapping part in the circle closing process is smaller than the distance of the overlapping gap, and the overlapping part can be inserted into the overlapping gap. According to the stator provided by the invention, the height of the part, which is firstly inserted into the overlapping gap in the circle closing process, of the overlapping part is optimized, so that the overlapping part can be smoothly inserted into the overlapping gap in the circle closing process, and the condition of unsmooth splicing caused by defects such as manufacturing errors or burrs in the related technology is further solved.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a stator, a motor, a compressor, a vehicle and a manufacturing method of the stator. Background technique [0002] like figure 1 and figure 2 As shown, the stator core is spliced ​​by multiple segmented cores 302'. In the process of manufacturing the stator core, firstly, the stator core is unfolded for insulation treatment, and the stator winding is arranged on the stator core, and then it is rounded to form a complete stator core. In the process of joining circles, certain difficulties are often encountered. [0003] For example, due to the existence of tension in the process of winding the stator winding, the axial direction of the stator core will be tighter and denser after winding, and the height of the punching piece 304' at the protruding part of the first side of the fracture will exceed the second side of the fracture The height of the recessed overlapping g...

AI Technical Summary

Problems solved by technology

In the subsequent rounding, the height of the burr 306' plus the height of the punching piece 304' is greater than the height of the recessed overlapping gap, which will cause the failure of the rounding, or the force during the rounding process will exceed the yield limit of the material , resulting in serious deformation of the stator core after being rounded and unable to return to the original stamping shape, resulting in unqualified inner and outer diameters of the stator and their roundness dimensions
