The invention provides a flat wire motor, a power assembly and an electric vehicle, a motor stator of the flat wire motor comprises a plurality of groups of winding slots, each group of winding slots comprises a plurality of winding slots, and all flat wires accommodated in a first winding slot in each group of winding slots are used for transmitting first-phase alternating current in three-phase alternating current. The flat wires in the second winding grooves are used for transmitting the first phase alternating current or the second phase alternating current, and the number of the flat wires used for transmitting the first phase alternating current in the second winding grooves is not equal to the difference value of the number of the flat wires used for transmitting the first phase alternating current in every two adjacent second winding grooves. The flat wires in the third winding grooves are used for transmitting the first phase alternating current or the third phase alternating current, and the number of the flat wires used for transmitting the first phase alternating current in the third winding grooves is not equal to the difference value of the number of the flat wires used for transmitting the first phase alternating current in every two adjacent third winding grooves. Therefore, the connection of the cross-layer flat wire for transmitting the in-phase alternating current has different spans, and the continuous short distance of the winding is realized, so that the harmonic magnetic field of the motor is weakened, and the NVH performance of the motor is improved.
