The present application discloses a stator, a flat wire motor, a powertrain, and a vehicle. The stator comprises: a stator core, of which the inner wall is provided with a plurality of stator slots uniformly distributed in the circumferential direction of the stator core; and phase windings each comprising a plurality of parallel branches rotational and symmetrical in the circumferential direction, each parallel branch comprising a plurality of hair-pin coils which are connected by means of connecting wires and have different pitches, N layers of hair-pin coils being arranged in any stator slot, and the hair-pin coils of each parallel branch traversing N slot layers in different stator slots, wherein When N=(2n+1)×2, the combination of the total number of slot layers occupied by each parallel branch in each stator slot is 2n, or 2n, 2n-1, 2n-2; When N=2n×2, the combination of the total number of slot layers occupied by each parallel branch in each stator slot is 2n, 2n-1, or 2n, 2n-1, 2n-2; and when N=2n+1, the combination of the total number of slot layers occupied by each parallel branch in each stator slot is n, n-1, or n, n-1, n-2. In this way, the stator provided by the present application can avoid generation of a current loop, reduce the manufacturing cost, and improve the processing and manufacturing efficiency.
