Abstract

The invention discloses a micro digital air suction motor. The micro digital air suction motor comprises a motor shell, a stator assembly and a rotor assembly, wherein the stator assembly and the rotor assembly are arranged in the motor shell; a front end cover is fixedly arranged at the front end of the motor shell; the outer diameter of the front end cover is less than the inner diameter of the motor shell; two axially symmetric connectors are arranged between the outer peripheral wall and the inner wall of the motor shell; two diversion inclined surfaces are arranged at the upper ends of the connectors; the outer peripheral wall of the front end cover axially extends inwards to form an air deflection surface; the inner wall of the motor shell, the diversion inclined surfaces and the air deflection surface are enclosed to form a trumpet-shaped diversion channel; the lower ends of the connectors extend toward the rear end of the motor shell; and the stator assembly is fixedly arranged on the extension parts of the connectors.

Description

technical field [0001] The invention relates to a brushless motor for a vacuum cleaner, in particular to a miniature digital suction motor. Background technique [0002] With the improvement of the quality of life, the use of vacuum cleaners is becoming more and more common. According to the types of vacuum cleaners, there are dry vacuum cleaners and wet and dry vacuum cleaners, and the vacuum cleaner motor is the heart of the vacuum cleaner. The vacuum cleaner motor is mainly composed of two parts: the motor part and the fan part. Vacuum cleaner motors have high requirements on speed. With the development of motor technology, motors with brush structures cannot meet the requirements of existing vacuum cleaners. However, brushless motors have high speed, small size and easy maintenance, and are more and more widely used in vacuum cleaners. . [0003] Invention patent name: a brushless motor for vacuum cleaners, patent application number: 201310024896.2 discloses a brushle...
