Abstract

The invention relates to the field of an electric tool, and discloses a stator mounting apparatus, a stator mounting structure and a fan system. The stator mounting apparatus (40) comprises a barrel-shaped shell (41) and a connecting piece (42) mounted on the inner wall of the shell; the connecting piece comprises a first part (421) connected to the shell and a second part (42) which extends from the first part (421) towards the inner side of the shell; a stator (50) is mounted on the second part; a radial positioning part (421a) for radially limiting the mounting position of the stator is arranged on the first part; and a circumferential positioning part (43) used for circumferentially limiting the mounting position of the stator is arranged on the shell. By virtue of the stator mounting apparatus disclosed in the invention, the mounting position of the stator can be accurately positioned, thereby ensuring the mounting precision of the stator; and therefore, accurate mounting of a rotor can be matched, and higher air gap uniformity can be obtained, thereby lowering motor noise.

Description

technical field [0001] The invention relates to an electric tool, in particular to a stator installation device, a stator installation structure and a fan system. Background technique [0002] High-speed motors have the advantages of small size, high power density, direct connection with high-speed loads, and improved system transmission efficiency. They are widely used in household appliances and machine tools. The speed of high-speed motors is usually higher than 10,000 r / min, and the speed of some small household vacuum cleaners is even as high as 110,000 r / min. The motor runs at a high speed, and the vibration noise is relatively large. At present, the noise of the motor can be reduced by the uniformity of the air gap between the stator core and the rotor magnetic ring. But this requires more precise control of the mounting accuracy of the stator and rotor. Contents of the invention [0003] The object of the present invention is to provide a stator installation dev...
