Abstract
A stator assembly, a motor, and a vehicle are disclosed. The stator assembly includes: a cylindrical stator core, where multiple stator slots spaced out along a circumferential direction of the stator core exist on the stator core; and a stator winding, where the stator winding includes multiple conductor segments. Each conductor segment includes an intra-slot part disposed in a stator slot of the stator core, and a first end and a second end that are disposed outside the stator core. The intra-slot part is connected between the first end and the second end, and the second ends of the multiple conductor segments form a welding end. All lead-out lines of each phase of the stator winding are located on the welding end.
