Document Type and Number:
WIPO Patent Application WO/2022/110378
Kind Code:

Abstract:
A stator (10), comprising an iron core (100) and windings (200). The windings (200) are wound on the outside of the iron core (100), and the iron core (100) comprises a plurality of laminated silicon steel sheets (110). Each silicon steel sheet (110) is provided with a plurality of over-cut notches (117); the over-cut notches (117) of the plurality of silicon steel sheets (110) are correspondingly arranged along the lamination direction of the plurality of silicon steel sheets (110) to form over-cut grooves (103); and both ends of each winding (200) abut against an over-cut groove (103). By providing over-cut grooves (103) at positions where both ends of each winding (200) and the iron core (100) are connected, the length of the windings (200) and the length of areas of the iron core (100) covered by the windings (200) are increased on the premise that the overall shape of the iron core (100) is unchanged, such that the performance of the stator (10) is enhanced.
