Explosion-proof three-phase disc brake asynchronous motor

The invention discloses an explosion-proof three-phase disc brake asynchronous motor, and belongs to the technical field of explosion-proof equipment. Comprising a shell, an explosion-proof cover, a front end cover, a main shaft, a rotor, a stator core with a winding and a brake pad, the rotor and the stator core with the winding are connected with the main shaft; a brake pad is arranged between the rotor and the inner wall of the cavity of the shell; a first threaded hole and a second threaded hole are formed in the end face of the shell, a brake release screw is connected into the first threaded hole in a matched mode, a steel ball is movably connected into one side of the inner end face of the first threaded hole, the two sides of the steel ball make contact with the brake release screw and the brake pad respectively, and an anti-explosion screwed plug is connected into the second threaded hole in a matched mode. By designing the brake release device and the observation structure for observing the abrasion
