Three-phase asynchronous motor

The utility model discloses a three-phase asynchronous motor, relates to the technical field of three-phase asynchronous motors, and is used for solving the technical problems of low efficiency and high long-term operation cost of the existing three-phase asynchronous motor. In the three-phase asynchronous motor, a stator core with a winding is pressed in a base, and a junction box is assembled at the top of the base; the stator core with the winding comprises a stator and a stator coil; a rear end cover and a flange end cover are assembled in the base, a first framework oil seal is mounted at an oil seal position of the rear end cover, and a second framework oil seal is mounted at an oil seal position of the flange end cover; the rear end cover and the flange end cover form a bearing chamber, the wave spring is assembled in the bearing chamber of the rear end cover, meanwhile, a rotor is installed in the bearing chamber, and a bearing is installed on the rotor in a pressing mode; the rotor comprises a cast-a
