The invention relates to an ultra-energy-saving 5500wW six-pole three-phase asynchronous electric motor, which comprises a stator and a rotor. The inner diameter of the stator, the length of an iron core, the groove shape and the dimension of a stator punching sheet groove, the inner diameter and the outer diameter of the rotor, the length of the iron core and the groove shape and the dimension of a rotor punching sheet groove are optimized and reasonably designed, the consumption of a stator winding is only 277.4W, the consumption of a rotor winding is only 173.4W, and the consumption of the iron core is only 34.2W. On the premise that the output power is 5500W, the input power required by the existing similar products is 34.2kW, the energy conversion efficiency is 86.3 percent, while the input power required by the ultra-energy-saving 5500W six-pole three-phase asynchronous electric motor is only 6.087kW, the energy conversion efficiency is 90.4 percent, so the energy sources are greatly saved, the rotating speed is improved from 967r / min to 1164r / min, the speed acceleration is increased by 20.4 percent, meanwhile, the stator buckle sheet groove center line is designed to penetrate through a position between the two grooves of the stator punching sheet groove, the radial electromagnetic force waves in the air gap are weakened, the electromagnetic vibration is reduced, and the electromagnetic noise is reduced.
