The invention relates to a switched reluctance motor of a cast-aluminum rotor structure. The switched reluctance motor comprises a shell, a rotary shaft, a stator iron core, a stator winding and a rotor iron core. The rotary shaft penetrates through the shell and is rotatably connected with the shell. The stator iron core is fixedly mounted in the shell. The stator winding is an integral pitch winding and mounted in a forming groove of the stator iron core. The rotor iron core is fixedly mounted on the rotary shaft, located in the shell, aligned with the stator iron core, and provided with motor air gaps along the radial direction of the stator iron core. By the switched reluctance motor, power output density of the switched reluctance motor is improved, effective material utilization rate and power factors are improved, vibration, noise, weight and cost of the switched reluctance motor are reduced, competitive advantages of the switched reluctance motor in the field of speed regulating especially in application filed of direct drive wind power generation, and accordingly traditional switched reluctance motors can be replaced widely, and the switched reluctance motor is applicable to the fields of speed regulating and power generation, especially direct drive wind power generation.
