The invention provides a switched reluctance motor comprising an external rotor; an internal rotor which is arranged in the internal part of the external rotor and coaxially rotates with the external rotor; and a stator which is arranged between the external rotor and the internal rotor, wherein the internal surface of the stator is provided with multiple stator internal teeth which are convex along the radial direction of the stator, and the external surface of the stator is provided with multiple stator external teeth which are convex along the radial direction of the stator. The two sides of the tooth top end of each stator internal tooth are convexly provided with stator internal pole shoes which are arranged along the circumferential direction of the internal rotor, the two sides of the tooth top end of each stator external tooth are convexly provided with stator external pole shoes which are arranged along the circumferential direction of the internal rotor. Windings are wound on the stator yoke parts of the stator. The stator comprises pole shoe structures so that winding safety can be enhanced under the premise that salient pole ratio of the motor is not reduced and performance of the motor is not reduced, and performance of the motor can also be enhanced. Therefore, the switched reluctance motor is simple in structure and great in performance and efficiency.
