A supper-efficient 1,500-watt 2-pole three-phase asynchronous motor comprises a stator and a rotor; the loss of a stator winding, a rotor winding and an iron core is greatly reduced, as the inner diameter and the outer diameter of both the stator and the rotor, the length of the iron core, and the amount, size and shape of the punching grooves are reasonably designed. Under the condition that the output power is 1,500 watt, compared with similar products, the motor provided by the invention has the advantages that the rotational speed is up to 2,911 r/min from 2,851 r/min, by 60 r/min; the total power loss is reduced to 237.8 W from 359.3 W, by 33.82 percent; the energy conversion efficiency is improved to 86.3 percent from 80.7 percent, by 5.6 percent and is about 2.1 percent higher than the highest international level standard, and the energy conversion efficiency is greatly improved; and meanwhile, a stator buckling piece groove center line is designed to pass through every two stator buckling piece grooves, so that radial electric magnetic waves in an air gap are weakened, the electromagnetic vibration is reduced and the electromagnetic noise is lowered.
