Title:
FLAT-WIRE ELECTRIC MOTOR STATOR AND FLAT-WIRE ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/247273
Kind Code:
A1
Abstract:
Disclosed in the present application are a flat-wire electric motor stator and a flat-wire electric motor. The stator comprises a stator core and a stator winding, wherein a stator winding of each phase comprises N parallel branches; star point connecting ends of all parallel branches are led out from different winding grooves on a connecting side, all the star point connecting ends, which are connected to a first star point connecting wire, in three-phase windings are led out from adjacent winding grooves on the connecting side, and all the star point connecting ends, which are connected to a second star point connecting wire, in the three-phase windings are led out from adjacent winding grooves on the connecting side; and N power source lead-out ends of windings of the same phase are led out from the same winding groove on the connecting side and are electrically connected by means of a power source lead-out wire, or the N power source lead-out ends of the windings of the same phase are led out from N adjacent winding grooves on the connecting side and are electrically connected by means of the power source lead-out wire, or some of the N power source lead-out ends of the winding of the same phase are led out from the same winding groove on the connecting side, and the remaining power source lead-out ends are led out from a winding groove adjacent to the same winding groove on the connecting side, and the N power source lead-out ends of a winding of the same phase are electrically connected by means of the power source lead-out wire.
