Problems solved by technology

[0005] 1. Use tight fit to combine the rotating shaft 10 with the magnet 20: there is a tight fit between the rotating shaft 10 and the shaft hole 21 of the magnet 20, so that the magnet 20 can be combined with the rotating shaft 10 and rotate synchronously, but because the magnet 20 itself The material is fragile, so this combination method can easily cause the magnet 20 to break. If the tight fit is not tight enough, the magnet 20 will not be able to drive the rotating shaft 10 to rotate synchronously.
[0006] 2. Use an adhesive to combine the rotating shaft 10 and the magnet 20: an adhesive is coated between the rotating shaft 10 and the shaft hole 21 of the magnet 20, so that the magnet 20 can be fixed and rotate synchronously with the rotating shaft 10, but the adhesive The adhesive itself has a certain lifespan, and the rotor structure is in a high-temperature and high-speed rotating environment for a long time, so the adhesive is easy to deteriorate and lose its adhesive effect

Abstract

The invention relates to a motor rotor which is characterized in that a magnet and two fixing seats are arranged around a rotation axis, and the two fixing seats are respectively located at both ends of the magnet, wherein the magnet and the rotation axis can be assembled in a light tight or loose state, and the two fixing seats and the rotation axis are matched in a tight fit state. The motor rotor is structured by limiting the clamp of the magnet in the preset position of the rotation axis and preventing the magnet from breaking. The two fixing seats are respectively provided with a butt surface tightly close to the two end surfaces of the magnet, wherein the butt surface can be a rough surface or is provided with a slot and a locating part for providing a stable jointing effect.

Description

technical field [0001] The invention relates to a motor rotor, in particular to a motor rotor which has a stable combination effect between a rotating shaft and a magnet and which can prevent the magnet from breaking. Background technique [0002] Such as figure 1 As shown, the existing DC brushless motor rotor includes a rotating shaft 10 and a magnet 20; [0003] Wherein, the magnet 20 is in the shape of a cylinder, and a shaft hole 21 is formed in the center so that the rotating shaft 10 can pass through the shaft hole 21 . [0004] In the existing motor rotor, there are two ways of combining the rotating shaft 10 and the magnet 20: [0005] 1. Use tight fit to combine the rotating shaft 10 with the magnet 20: there is a tight fit between the rotating shaft 10 and the shaft hole 21 of the magnet 20, so that the magnet 20 can be combined with the rotating shaft 10 and rotate synchronously, but because the magnet 20 itself The material is fragile, so this combination met...
