High-speed motor and blower

Abstract

The invention discloses a high-speed motor. The motor comprises a housing, a mounting part, a rotor assembly and a stator assembly, wherein the front end of the housing is an air inlet end, and the front end surface of the housing is provided with an undulating air inlet lip; the mounting part is located in the housing, a mounting cavity is formed in the mounting part, a plurality of air guide blades are fixedly connected between the mounting part and the housing, an air duct is formed between the housing and the mounting part, the housing is provided with a variable-diameter inner peripheral wall at the position of the air duct, and the inner diameter of the variable-diameter inner peripheral wall is gradually reduced from the two ends of the air duct to the middle of the air duct; the rotor assembly is mounted in the mounting cavity, the rotor assembly is provided with a rotating shaft, the rotating shaft is fixedly connected with a first fan blade in front of the mounting part, and one end, far away from the first fan blade, of the rotating shaft is fixedly connected with a magnetic ring; and the stator assembly is mounted in the mounting cavity, and the stator assembly is used for driving the magnetic ring to rotate. Compared with the prior art, the high-speed motor can better adapt to a high-rotating-speed state, so that the user experience of a blower is improved. Meanwhile, a blower applying the high-speed motor is further provided.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to high-speed motors and hair dryers. Background technique [0002] At present, most hair dryers are driven by brushless motors. Compared with brushed motors, brushless motors do not generate carbon brushes or electric sparks during high-speed operation, are safer and more reliable, and have a longer service life. [0003] With the continuous improvement of living standards, users gradually pay more attention to the wind speed and volume requirements of hair dryers. In order to meet the needs of users, only the speed of the brushless motor can be increased, but the increase of the speed of the brushless motor will produce greater wind noise. , and cause wind fluid to disperse and not gather. For this reason, it is necessary to improve the existing brushless motor so that it can better adapt to the state of high speed. Contents of the invention [0004] The purpose of the inventio...
