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.

    本申请提供一种扁线电机、动力总成及电动车,扁线电机的电机定子包括多个绕组槽和沿扁线电机径向排列的N圈扁线,N为大于等于2的整数,每圈扁线包括多对沿扁线电机周向排列的扁线,每个绕组槽用于容纳每圈扁线中的一对扁线,每对扁线包括外层扁线和内层扁线。其中,N圈扁线包括第一圈扁线,第一圈扁线中的外层扁线包括第一扁线、第二扁线和第三扁线,第一扁线、第二扁线和第三扁线和与其各自对应连接的内层扁线之间分别通过三种长度互不相同的跨线段连接。第一扁线、第二扁线和第三扁线和与其各自对应连接的内层扁线之间分别通过三种长度互不相同的跨线段连接,可以使绕组实现连续短距的效果,改善扁线电机的NVH性能。
