The invention discloses a double-stator magnetic suspension switch reluctance starting/power generation machine which sequentially comprises an inner stator, a rotor and an outer stator from inside to outside, the inner stator, wherein the rotor and the outer stator are in the salient pole type and are nested in a concentric mode; M main winding poles are arranged on the outer stator at equal intervals, and each main winding pole is provided with a main winding which achieves starting and power generation functions; N rotor salient poles are arranged on the rotor at equal intervals; O suspension poles are arranged in the inner stator at equal intervals, and each suspension pole is provided with a suspension winding which achieves a rotor suspension function; magnetic flow paths of the main windings are independent of magnetic flow paths of the suspension windings, the coupling problem between the starting/ power generation function and the suspension function is solved, aligning areas of the suspension poles and the rotor are equal to pole widths of the suspension poles, and radial suspension performance is improved. The machine integrates the starting and power generation functions and the rotor self-suspension function, the structure of an engine can be more compact, and the engine is convenient to maintain and control.
