Problems solved by technology

[0002] The waterproof and dustproof performance of the existing external rotor motor is average. After water droplets and dust enter the interior of the external rotor motor, they will directly contact the electronic components in the control box or the circuit board in the circuit board assembly, which will easily cause a short circuit. Therefore, the existing There is still room for improvement in the structure of the outer rotor motor

Abstract

The invention discloses a waterproof motor structure. The structure comprises an end cover, a control box, an outer rotor assembly, a stator assembly and a circuit board assembly, wherein the stator assembly is fixed on the front end side of the end cover; the control box is arranged on the rear end side of the end cover and is fixedly connected with the end cover through mounting screws; a secondseal ring is arranged between the end cover and the control box; the stator assembly is sleeved by the outer rotor assembly in a rotatable manner, and the outer rotor assembly is connected with the end cover through a mounting flange; the control box comprises a control box body with an opening, and a box cover arranged on the control box body; the box cover is used for closing the opening; wirethreading holes are formed in the control box body; and an electrical wire waterproof connector is arranged in each wire threading hole. The waterproof motor structure provided by the invention has the advantages of good waterproof performance and good use effects.

Description

technical field [0001] The invention relates to a waterproof structure of a motor, in particular to a waterproof structure of an outer rotor motor. Background technique [0002] The waterproof and dustproof performance of the existing external rotor motor is average. After water droplets and dust enter the interior of the external rotor motor, they will directly contact the electronic components in the control box or the circuit board in the circuit board assembly, which will easily cause a short circuit. Therefore, the existing There is still room for improvement in the structure of the outer rotor motor. Contents of the invention [0003] In view of this, the present invention aims to provide a motor waterproof structure with a reasonable structure, and the motor waterproof structure has a good waterproof and dustproof effect. [0004] The technical scheme that realizes the object of the present invention is: [0005] A motor waterproof structure, comprising an end cov...
