Problems solved by technology

During the operation of the existing motor 9, the rotating shaft 932 will rotate relative to the stator 92, so there must be a gap between the rotating shaft 932 and the first cover 911 or the metal shell 94 to avoid the first The cover body 911 or the metal shell 94 hinders the rotation of the rotating shaft 932; therefore, external moisture easily invades the interior of the existing motor 9 through the aforementioned gap, causing the moisture barrier effect of the motor 9 to be unsatisfactory, and it is difficult to improve the motor 9. Moisture-proof effect of existing motor 9

Abstract

A motor is used to solve the problem that the existing motor blocks the poor effect of water vapor. The motor of the present invention includes: a housing; a stator provided inside the housing; a rotor rotatably coupled to the stator; and a leakage preventing member disposed in the housing, wherein the rotor has a rotation shaft; at least one end of the rotation shaft protrudes outside the housing; the leakage preventing member is provided with a through hole for the rotation shaft to pass through.

Description

technical field [0001] The present invention relates to a motor, in particular to a motor capable of improving the moisture barrier effect. Background technique [0002] Please refer to figure 1 , it is a kind of existing motor 9, and this existing motor 9 can utilize a first cover body 911 of an isolation cover 91 and a second cover body 912 to cover the permanent magnet group 931 of its stator 92 or rotor 93 Thereby, the isolation cover 91 can isolate the internal components of the existing motor 9 from the outside to block moisture or foreign matter, and provide good moisture-proof or dust-proof effects for the existing internal components of the motor 9 . In addition, the conventional motor 9 also includes a metal shell 94, so that the isolation cover 91 can be further accommodated inside the metal shell 94, so that the metal shell 94 can provide better structural strength and protection effect. [0003] However, the rotor 93 of the existing motor 9 also includes a rot...
