An explosion-proof motor is disclosed according to one embodiment of the present invention. The motor comprises a rotation axis which is fixed on the motor; a motor frame; and a labyrinth seal which is sealed between the rotation axis and the motor frame; maintains a gap with the rotation axis in order not to generate abrasion when the rotation axis is rotated; and has a mirror structure which blocks spreading the flames, which are generated by explosion when the motor explosion is tested, to the outside of the motor frame. The rotation axis is penetrated through the motor frame. The labyrinth seal is combined with the rotation axis by threads and heat. |
