Abstract

The invention provides a stator core, a motor, a compressor and a vehicle. The stator iron core comprises a plurality of block iron cores, the plurality of block iron cores are sequentially connected end to end around the axis of the stator iron core, and each block iron core comprises a plurality of laminated punching sheets; each block iron core comprises a stator yoke and stator teeth which are connected with each other, the stator teeth are located between the axes of the stator yoke and the stator iron core, and the stator yokes and the stator teeth of any two adjacent block iron cores define a stator slot; the wall surface, facing the axis of the stator core, of the stator yoke is a splicing surface; and along the circumferential direction of the stator iron core, at least one part of the joint of any two adjacent splicing surfaces is in smooth transition. By reasonably arranging the structure of the block iron core, the size of the joint of the two adjacent stator yokes can be increased in the radial direction of the stator iron core, the situation that the use performance of the motor is affected due to the fact that the size of the joint of the two adjacent stator yokes is too small is avoided, and the running stability and the working efficiency of the motor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator core, a motor, a compressor and a vehicle. Background technique [0002] related technologies, such as Figure 14 to Figure 17 As shown, the stator core 100' includes a plurality of segmented iron cores 110', and each segmented iron core 110' includes a plurality of stacked punching pieces 120'. The wall surface of the stator yoke of the segmented iron core 110' facing the axis of the stator iron core 100' is inclined, so that the joint 130' of two adjacent stator yokes forms a sharp angle, so that along the radial direction of the stator iron core 100', The reduced size of the junction of two adjacent stator yokes affects the performance of the motor and interferes with the winding nozzle, affecting the winding effect. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art....
