Flat wire motor stator assembly, flat wire motor and automobile

The invention provides a flat wire motor stator assembly, a flat wire motor and an automobile, and relates to the field of motors, the flat wire motor stator assembly comprises a U-phase winding, a V-phase winding and a W-phase winding which are arranged in a staggered manner along the circumferential direction of a motor stator, each phase winding comprises a winding body and a leading-out wire, and at least one end of the winding body along the current flowing direction is connected with the leading-out wire. The leading-out wire comprises a leading-out wire body located in a slot of the motor stator and a supporting foot located on the hairpin side of the motor stator. At the same end parts of the U-phase winding, the V-phase winding and the W-phase winding, leading-out wire bodies of the U-phase winding, the V-phase winding and the W-phase winding are sequentially arranged at intervals along the circumferential direction of the motor stator, and a supporting foot of the U-phase winding and a supporting fo
