A permanent magnet DC motor capable of dustproof, shockproof and moistureproof

Abstract

The invention relates to a dustproof, shockproof and moistureproof permanent magnet direct current motor, comprising a permanent magnet direct current motor, a mounting seat is installed on the bottom outer wall of the permanent magnet direct current motor, and mounting screw holes are provided on the top four corner outer walls of the mounting seat, An anti-vibration mechanism is arranged on the inner wall between the permanent magnet DC motor and the mounting seat, and an active turbine is installed on the top outer wall of the permanent magnet DC motor, and the rotating shaft of the active turbine is coaxially connected with the drive shaft of the permanent magnet DC motor; The rotation of the working drive shaft will drive the active turbine to work. The active turbine sucks air in the bottom tank through the suction pipe, and filters the dust in the external ambient air through the filter screen set on the bottom tank, and the filtered air enters the bottom tank By mixing with the internal drying block, the moisture vapor in the air is absorbed and eliminated, so that the dry and dust-removed air is input into the permanent magnet DC motor, and the permanent magnet DC motor is dust-proof and moisture-proof.

Description
