High-rotating-speed motor and assembling method thereof

Abstract

The invention discloses a high-rotating-speed motor and an assembling method thereof. The high-rotating-speed motor comprises a machine shell, a rotating shaft and a bearing sleeve, wherein the machine shell is of an annular structure with the left end and the right end open, an installation ring coaxial with the machine shell is arranged in the machine shell, the outer diameter of the installation ring is smaller than the inner diameter of the machine shell, the length of the installation ring in the left-right direction is smaller than the length of the machine shell in the left-right direction, a plurality of air guide pieces are evenly distributed between the installation ring and the inner wall of the machine shell, a stator installation cavity and a bearing installation cavity are sequentially formed in the installation ring from left to right; an annular protruding part is arranged in the middle of a stator installation cavity of the installation ring, the outer wall of the right portion of the bearing sleeve is matched with the inner wall of the left portion of the machine shell, the outer wall of the right portion of the bearing sleeve is inserted into the inner wall of the left portion of the machine shell, the rotating shaft is inserted into the bearing sleeve and the machine shell in the left-right direction, the middle of the rotating shaft is sleeved with a magnetic ring, and a stator assembly is mounted in the stator mounting cavity. The high-rotating-speed motor has the advantages of being not prone to resonance, low in noise and the like.

Description

technical field [0001] The technical field of motors of the present invention specifically relates to a high-speed motor and an assembly method thereof. Background technique [0002] Because of the high speed, the volume of the high-speed motor is much smaller than that of the ordinary dry motor, and the high-speed motor cancels the deceleration mechanism of Chuanrong. The high-speed motor has high power density, effectively saves materials, high transmission efficiency, and fast dynamic response. However, the electrical appliances used by consumers on the market, such as fans, hair dryers, vacuum cleaners and other electrical appliances, are prone to resonance when running at high speed, and the operating noise is large. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a high-speed motor with low resonance and low noise and an assembly method thereof. [0004] In order to solve the problems of the tech...
