The utility model relates to a permanent magnet type switch reluctance motor, more specifically a spiral permanent magnetic field motor. The utility model comprises a machine seat, a bearing, a control system, a rotor, a stator and a winding. The utility model is characterized in that the rotor is composed of an annular permanent magnet, a rotor core and a rotary shaft which are fixedly arranged to form a whole from outside to inside, wherein an N pole and an S pole on the axial annular column surface of the annular permanent magnet mutually fit so as to form a spiral shape; the stator is composed of a roofing pole and an annular seat, wherein the annular seat is provided with an inner wall bulge; the roofing pole is fixedly connected with the inner wall bulge, and the annular seat is fixedly connected with the machine seat; the inner wall of the roofing pole corresponds to the outer wall of the annular column surface of the annular permanent magnet; the winding is sheathed on the inner wall bulge of the annular seat; the control system provides electricity for the winding intermittently. The utility model can adopt the manufacturing process and the material of a traditional motor, the prior art is fully used for making and the utility model has an obvious energy saving effect.
