Specific embodiment
Core of the present utility model is to provide a kind of magnetic shoe, to lift the adhesion of magnetic shoe and rotor core, and drops
Low eddy-current loss；
Another core of the present utility model is to provide a kind of rotor and motor.
Hereinafter, referring to the drawings embodiment is illustrated.Additionally, embodiments illustrated below is not to described in claim
Utility model content play 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 the utility model described in claim.
Refer to Fig. 4 and Fig. 5, the structural representation of the magnetic shoe that Fig. 4 is provided by this utility model embodiment；Fig. 5 is Fig. 4
Top view.
Magnetic shoe in this utility model embodiment includes magnetic shoe body, and magnetic shoe body is used for the surface fixing with rotor core
For fixation surface, the fixation surface of magnetic shoe body opens up fluted 101, groove can increase the reserved of glue.
Magnetic shoe disclosed in this utility model embodiment, opens up fluted 101, Ke Yibao in the fixation surface of magnetic shoe body
After card magnetic shoe is bonding with rotor core, due to fluted 101 presence, hence in so that can retain between magnetic shoe and rotor core
There are a certain amount of glue, and then the retentivity of raising magnetic shoe, improve the adhesion of magnetic shoe and rotor core.Magnetic shoe is recessed simultaneously
Cross-sectional area at groove 101 reduces, and can effectively reduce the eddy-current loss of magnetic shoe.
In this utility model one specific embodiment, the axial direction extending perpendicularly to magnetic shoe body of groove 101；When
So, the bearing of trend of groove 101 also can be parallel to the axial direction of magnetic shoe body；The bearing of trend of groove 101 also can be with magnetic shoe body
Axial direction angle be more than 0 ° and be less than 90 °.I.e. the bearing of trend of groove 101 is permissible with the angle at the axial right angle of magnetic shoe body
Arbitrarily, as long as groove 101 is opened up on fixation surface, just so that remaining with a certain amount of glue between magnetic shoe and rotor core
Water, and then improve the adhesion of magnetic shoe and rotor core.
In this utility model one specific embodiment, the edge of fixation surface is run through at the two ends of groove 101.Need explanation
It is that the two ends of groove 101 also can will be arranged in the centre of fixation surface, this reality by groove 101 not through the edge of fixation surface
With type, the position of groove 101, shape, length are not limited.
In this utility model one specific embodiment, the cross section of groove 101 can be triangle, rectangle or arc, but
It is not limited to above-mentioned three kinds, can be arbitrary shape.When groove 101 is a plurality of, the shape of cross section of each bar groove 101 is permissible
Identical also can be different.Groove 101 can be spaced apart multiple, also can only arrange one, the quantity of groove 101 and spacer
From it should to be determined with the size of magnetic shoe.The depth of groove 101 does not lay down hard-and-fast rule, can be according to the physical dimension of magnetic shoe, electricity
The factors such as machine rotating speed adjust.
Further, magnetic shoe when having multiple groove 101 it is preferable that each groove 101 is arranged in parallel, each groove
101 are equally spaced, and certainly also can arbitrarily arrange.
The invention also discloses a kind of rotor, including magnetic shoe, magnetic shoe is magnetic shoe disclosed in technique scheme.
Because above-mentioned magnetic shoe has the effect above, the rotor with this magnetic shoe also has corresponding effect, and here is omitted.
