Document Type and Number:
WIPO Patent Application WO/2024/021885
Kind Code:
A1
Abstract:
A stator assembly (100), a motor (1000), and a vehicle (2000). The stator assembly (100) comprises: a stator iron core (10), each stator slot (101) having M layers; and a stator winding (20), each phase of winding comprising at least one branch, each branch comprising two first conductors (21), a plurality of second conductor groups and a plurality of third conductors, each second conductor group comprising at least one second conductor (22), and every two adjacent second conductor groups being connected in series by means of the corresponding third conductor (23). The first conductors (21) are I-type conductors, and in-slot portions of the first conductors (21) are disposed on the innermost layers or the outermost layers of the stator slots (101); both the second conductors (22) and the third conductors (23) are U-shaped conductors, two connecting portions (33) of each second conductor (22) are close to each other and extend, two in-slot portions (31) of each second conductor (22) are located on adjacent layers of different stator slots (101), two connecting portions (33) of each third conductor (23) are bent in a same direction, and two in-slot portions (31) of each third conductor (23) are located on the innermost layers or the outermost layers of different stator slots (101).
