Summary:The utility model relates to a high efficient dual-stage single-phase capacitive asynchronous motor, which comprises a rotor, a stator and a stator winding, and is characterized in that: the stator winding adopts a time-space phase winding structure, and consists of a reference winding, a secondary winding and a middle winding, the space phase angle between windings is 120 degrees, and the time phase angle of winding is 60 degrees. The rotor is a deep slot high torque rotor, the slot length is higher than 1/3 of the radius of rotor. A specific time-phase phase is formed among the windings, the reference wave magnetic field of motor air gas is changed into a round magnetic field, the negative-order magnetic potential is overcome, and the negative order is ''0'', thereby ensuring the motor efficiency up to 83.07% with a low temperature rise; compared with the motor with the same power, the utility model can save copper for 14%, silicon steel sheet for 21%, and electric power for 23.58%. The utility model can be widely used for various small size machines and electrical household appliances.
