The utility model discloses a voltage-multiplying three-phase asynchronous motor, which comprises a stator and a rotor, the stator consists of a base and a stator core with a winding, the stator corewith the winding comprises a stator core and a coil winding embedded in a groove of the stator core, and the rotor consists of a rotating shaft and a cast aluminum rotor. According to the utility model, the motor has two parallel circuits at low voltage and one parallel circuit at high voltage; generally, a 2Y/Y connection method (corresponding to low voltage/high voltage) is adopted for a motor with rated power less than 4kW; the motor with the rated power larger than or equal to 4 kW is connected in a 2/connection mode (corresponding to low voltage/high voltage). According to the utility model, the concentric unequal-turn distribution winding is adopted, the winding has more flexible design space compared with an equal-turn double-layer lap winding, and the design that the number of conductors in each groove is
