The invention provides a motor used for a compressor of a turbo-refrigerator. The labyrinth sealing member is arranged or detached with respect to a rotary shaft of a motor of a turbo compressor, and the broken or damaged labyrinth sealing member can be prevented, and the integrity of the sealing mechanism can be guaranteed, and therefore the simplification of the assembly operation of the labyrinth sealing member can be prevented, and the assembly time can be reduced. The labyrinth sealing member is disposed in the motor of the compressor, and the labyrinth sealing member is provided with a labyrinth sealing body, which is opposite to the outer periphery of the rotary shaft of the motor for the shaft sealing, and is formed by the gear rows. The labyrinth sealing part is provided with a plurality of guiding parts in a separated manner,and the guiding parts are provided with the same internal diameter as the labyrinth sealing body, and a plurality of circular grooves are formed in the rotary shaft corresponding to the guiding parts. |
