Embodiment
The purpose of present embodiment is to provide a kind of rotor, its magnet is magnetic preferably and magnetic distribution is equal
It is even, motor performance can be effectively improved.Moreover, present embodiment additionally provides the motor including the rotor.
Hereinafter, embodiment is illustrated referring to the drawings.In addition, embodiments illustrated below is not to described in claim
Utility model content rise any restriction effect.In addition, the full content of the composition represented by example below is not limited to conduct
Necessary to the solution of utility model described in claim.
- Fig. 7, a kind of rotor provided in this embodiment are please referred to Fig.2, including is provided with the rotor of multiple magnetic grooves 11
Iron core 15, is filled with magnetic powder in each magnetic groove 11.It should be noted that the magnetic powder in the present embodiment is connected as by sintering processing
One entirety, this is integrally magnet 12.
It should be noted that in technical solution provided in this embodiment, magnetic powder sinters the magnet 12 of formation certainly from carrying magnetic
Band magnetic pole orientation, is not required to carry out magnetization treatment again, saves process.Rotor core 15 is stacked by rotor punching to be formed, and is turned
Sub- punching is as shown in Figure 7.
Such magnet 12 can be full of whole magnetic groove 11, gap be not present between magnet 12 and magnetic groove 11, motor performance is more
It is good.Moreover, do not deposit by the magnetic pole of magnet 12 it is anti-loaded in assembling process the problem of, and production efficiency is higher.
The rotor formed relative to injection molding manner of the prior art, rotor provided in this embodiment, magnet
The material such as mixed plastic or sizing material, relatively high magnetism are not required in 12, and Distribution of Magnetic Field is uniform, substantially increases motor performance.
In the preferred solution of the present embodiment, can also the axial direction of rotor core 15 be provided at both ends with magnetic end ring 13, with
Magnet 12 is sealed.
Magnetic 13 one side of end ring is used to magnet 12 being sealed in the magnetic groove 11 of rotor core 15, another aspect magnetic end
Ring 13 has magnetism, can reduce magnet 12 as the height used in sensing hall signal, reduce production cost.
It should be noted that in the present embodiment, magnetic end ring 13 also can by the way of magnetic powder is sintered with rotor core 15
The formula that links into an integrated entity structure.Such as in order to save process, while magnet 12 in magnetic groove 11 are sintered, by magnetic end ring 13
Also sinter in the lump at the both ends of rotor core 15.The height of rotor core 15 can specifically be set according to actual conditions, herein not
Specifically limited again.
