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 winding slots and N circles of flat wires arranged along the radial direction of the flat wire motor, N is an integer greater than or equal to 2, each circle of flat wires comprises a plurality of pairs of flat wires arranged along the circumferential direction of the flat wire motor, each winding slot is used for accommodating one pair of flat wires in each circle of flat wires, and the winding slots are arranged in the winding slots. Each pair of flat wires comprises an outer-layer flat wire and an inner-layer flat wire. Wherein the N circles of flat wires comprise a first circle of flat wires, outer-layer flat wires in the first circle of flat wires comprise a first flat wire, a second flat wire and a third flat wire, and the first flat wire, the second flat wire and the third flat wire are respectively connected with the inner-layer flat wires correspondingly connected with the first flat wire, the second flat wire and the third flat wire through three cross-wire sections with different lengths. The first flat wire, the second flat wire and the third flat wire are respectively connected with the inner-layer flat wires correspondingly connected with the first flat wire, the second flat wire and the third flat wire through three cross-wire sections with different lengths, so that the winding can realize a continuous short-distance effect, and the NVH (Noise Vibration and Harshness) performance of the flat wire motor is improved.
