Explosion-proof ultrahigh-efficiency three-phase asynchronous motor with cast copper rotor

The utility model relates to an explosion-proof ultrahigh-efficiency three-phase asynchronous motor with a cast copper rotor. The explosion-proof ultrahigh-efficiency three-phase asynchronous motor with the cast copper rotor comprises a rotor, a stator, outer bearing covers, bearings, inner bearing covers, end covers, a pedestal and a terminal box, wherein two ends of a rotating shaft in the rotor are installed on the end covers through bearings; the inner bearing cover and the outer bearing cover are arranged on two sides of each bearing respectively; the rotor is a cast copper rotor; a rotor iron core in the cast copper rotor is formed by laminating rotor laminations with the same size and shape; guiding strip holes are uniformly distributed at the periphery of the each rotor lamination; the guiding strip holes in each rotor lamination are laminated to form a guiding strip slot in the rotor iron core; a copper guiding strip is cast in the guiding strip slot; copper end rings are arranged at two ends of the
