The invention discloses an improved single-phase shaded pole asynchronous motor, and relates to the technical field of motor manufacturing. The motor comprises a main stator assembly, an auxiliary stator assembly, a rotor assembly 19, a front bracket 7, a rear bracket 6 and a pair of bracket fixing screws 5. The auxiliary stator assembly is inserted into the lower part of the main stator assembly; the rotor assembly 19 penetrates through the upper part of the main stator assembly, and two ends of the rotor assembly 19 are respectively provided with the front bracket assembly 7 and the rear bracket 6; the main stator assembly comprises a main stator iron core 4, a set of large-wire-diameter short circuit rings and a set of small-wire-diameter short circuit rings. The motor has the characteristics of improving the air gap flux density waveform of the main stator iron core, reducing the flux leakage amount, increasing the effective magnetic conduction volume of the middle part of the main stator iron core, incre
