Abstract

The invention discloses a noise reduction motor. The noise reduction motor comprises a motor shell; a mounting base comprising a stator cavity and a rotor cavity, wherein the mounting base is locatedin the motor shell, so that an air flow channel is formed between the mounting base and the motor shell; a plurality of obliquely arranged air deflectors, wherein the mounting base is fixedly connected with the motor shell through the plurality of air deflectors; a rotor bearing mounted in the rotor cavity; a stator arranged in the stator cavity; a rotor with a blade, wherein one end of the rotorpenetrates through the rotor bearing and extends into the stator; and a damping rubber sleeve arranged outside the motor shell in a sleeving manner. When airflow flows through the air flow channel internally provided with the multiple air deflectors, rotational flow can be generated, the stability of air pressure fluctuation is enhanced, and air noise generated when the airflow flows through the air flow channel is effectively reduced. In addition, the damping rubber sleeve can weaken vibration generated when the motor works, and the noise reduction performance of the motor is further improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a noise reduction motor. Background technique [0002] Although the existing motors used for hair dryers or vacuum cleaners have the advantages of high speed and small size, they can generate relatively high decibel noise during work, which seriously affects the life and study of people around them. In view of this, it is necessary to improve the existing motor to solve the above problems. Contents of the invention [0003] The invention aims to solve at least one of the technical problems in the prior art. For this reason, the invention proposes a noise reduction motor, which can effectively reduce the noise generated during operation. [0004] A noise reduction motor according to the first embodiment of the present invention includes: [0005] Motor housing; [0006] The mounting base includes a stator cavity and a rotor cavity, the stator cavity communicates with the roto...
