Problems solved by technology

However, when the adhesive fails or the adhesive force is insufficient, the centrifugal force generated by the high-speed operation of the rotor will cause the magnetic tiles to be thrown out, and the gap between the two magnetic tiles and the air will generate a certain amount of noise.

Abstract

The invention discloses a DC brushless motor, which comprises a stator, a rotor and at least one annular heat-shrinkable tube, wherein the rotor is arranged inside or outside the stator in a rotatable manner, and the rotor comprises a rotor core and a plurality of magnetic tiles arranged on the outer surface of the rotor core; and the heat-shrinkable tube sleeves the plurality of magnetic tiles. According to the DC brushless motor provided by the invention, the magnetic tiles can be effectively fixed on the outer surface of the rotor core, and the noise generated by the air and a gap between every two adjacent magnetic tiles can be reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a DC brushless motor. Background technique [0002] In the related art, the magnetic tiles in the motor and the rotor core are pasted and fixed by an adhesive. However, when the adhesive fails or the adhesive force is insufficient, the centrifugal force generated by the high-speed operation of the rotor will cause the magnetic tiles to be thrown out, and the gap between the two magnetic tiles and the air will generate a certain amount of noise. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a DC brushless motor, which can effectively fix the magnetic tiles on the surface of the rotor iron core, and reduce the noise generated by the gap between two adjacent magnetic tiles and the air. [0004] According to the brushless DC motor according to the...
