一种减少电机涡流损耗的定子、电机及压缩机
By staggering the six weld seams of the stator core and incorporating a notch design, the problem of increased eddy current losses caused by excessively long weld seams in traditional stator cores is solved, thereby reducing motor eddy current losses and improving efficiency.

Abstract
Claims
1. A stator for reducing eddy current losses in an electric machine, comprising a stator core of a plurality of silicon steel sheets stacked together, characterized in that: The outer contour of the stator core has six welds, with two diagonally arranged welds forming a group. In the first group, weld A is located between the first silicon steel sheet and the middle silicon steel sheet, and weld B is located between the middle silicon steel sheet and the last silicon steel sheet. In the second group, weld C is adjacent to weld A and is located between the middle silicon steel sheet and the last silicon steel sheet, while weld D is located between the first silicon steel sheet and the middle silicon steel sheet. In the third group, both welds are located on the silicon steel sheet in the middle section.
2. A stator for reducing the eddy current loss of an electric machine according to claim 1, characterized in that: Each silicon steel sheet has a notch corresponding to each weld joint.
3. A stator for reducing the eddy current loss of an electric machine according to claim 1, characterized in that: The ratio of the length of each weld to the total height of the stator core is 1 / 3 to 1 / 2.
4. An electric machine characterized by: Includes the stator as described in any one of claims 1-3.
5. A compressor characterized by: Includes the motor described in claim 4.
