Abstract

The invention relates to a motor of an outer-rotor blower. The motor comprises a main shaft, wherein a stator is installed on the main shaft fixedly; a rotor is arranged on the outer side of the stator; and a fan blade is fixed on the rotor coaxially. The motor is characterized in that the lower end of the main shaft is arranged in a first bearing; a rear end cover is arranged on the first bearing and fixed with the rotor; a support seat is arranged at the lower end of the rear end cover; the lower end of the main shaft is fixed in the support seat; a second waterproof and dustproof seal ring is arranged between the rotor and the rear end cover, a first waterproof and dustproof seal ring is arranged between the rear end cover and the main shaft; and a small shaft is arranged inside the rotor and in a second bearing. The motor provided by the invention has an ingenious, advanced, compact and reasonable structure and is repaired conveniently, thereby greatly reducing the cost. The motor has good stability performance, and filles up the blank of the outer-rotor blower motor (IP55) without waterproof and dustproof effects in China. In addition, the motor has excellent waterproof and dustproof effects, wherein the waterproof and dustproof level reaches up to IP55.

Description

technical field [0001] The invention relates to an outer rotor fan motor, in particular to an outer rotor fan motor whose protection level reaches IP55. Background technique [0002] The existing external rotor fan motor has the characteristics of compact structure, space saving, and exquisite design. The motor is installed in the middle of the impeller to achieve the maximum cooling effect on the motor itself. However, the dustproof and waterproof effects of the existing external rotor fan motors are relatively poor, and the existing external rotor fan motors with a protection level of IP44 cannot be maintained, resulting in relatively high costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an outer rotor fan motor with good dustproof and waterproof effects. [0004] According to the technical solution provided by the present invention, an outer rotor fan motor includes a main shaft,...
