An integrated AC motor for a hybrid electric vehicle, including a stator, an inner rotor, an outer rotor, a solid shaft, a hollow shaft, a bearing, an end cover, and a casing, and the left end of the solid shaft is sequentially assembled with an inner bearing, a hollow shaft, an outer bearing, and a left end cover , the right end is equipped with a bearing and a right end cover in sequence, and the middle of the solid shaft is equipped with an inner rotor, a stator, an outer rotor, an outer rotor sleeve and a casing in sequence in the vertical direction, the inner rotor is fixed on the solid shaft, and a connecting piece is provided at one end of the stator. The part is connected with the right end cover, and the outer rotor sleeve is connected with the rotating part fixed on the hollow shaft through screws, and two structures of double-ended shaft extension and single-ended shaft extension can be used. The inner and outer walls of the stator have grooves for embedding winding coils, and two sets of independent three-phase symmetrical windings are respectively embedded in the grooves of the inner and outer walls; the inner and outer double rotors can be either squirrel-cage or Various permanent magnet rotor structures; the number of poles of the two sets of windings embedded in the inner and outer walls of the stator can be the same or different.
