Title:
STATOR, FLAT WIRE MOTOR, POWER ASSEMBLY, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/071456
Kind Code:
A1
Abstract:
The present application provides a stator, a flat wire motor, a power assembly, and a vehicle, for improving the flexibility of a design structure of a stator winding, and capable of changing wire inlet ends and wire outlet ends of parallel branches according to needs. The stator comprises a stator core and a stator winding; M winding grooves are formed on the inner wall of the stator core; the M winding grooves are evenly arranged on the inner wall of the stator core in the circumferential direction; any winding groove extends in the axis direction of the stator core; the stator winding comprises flat wire conductors inserted into the winding grooves; N layers of flat wire conductors are arranged in any winding groove; a phase unit of a first phase winding, a phase unit of a second phase winding and a phase unit of a third phase winding are sequentially and periodically arranged along the inner wall of the stator core; each phase winding comprises P parallel branches; any parallel branch is connected to M·N/3P layers of flat wire conductors, and any flat wire conductor in any parallel branch is connected to the same-phase flat wire conductor in the adjacent layer or the same layer in the winding groove of the adjacent span.
