Detailed description of the invention
The core of the present invention is to provide a kind of magnetic shoe, to promote the adhesion of magnetic shoe and rotor core, and reduces whirlpool
Stream loss；
Another core of the present invention 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
Summary of the invention play any restriction effect.It addition, the full content of the composition represented by example below is not limited to as right
Necessary to the solution of the invention described in requirement.
Refer to the structural representation of the magnetic shoe that Fig. 4 and Fig. 5, Fig. 4 are provided by the embodiment of the present invention；Fig. 5 is bowing of Fig. 4
View.
Magnetic shoe in the embodiment of the present invention includes magnetic shoe body, and magnetic shoe body is solid for the surface fixing with rotor core
Determining surface, the fixing surface of magnetic shoe body offers groove 101, groove can increase the reserved of glue.
Magnetic shoe disclosed in the embodiment of the present invention, offers groove 101, it is ensured that magnetic on the fixing surface of magnetic shoe body
After watt bonding with rotor core, due to the existence of fluted 101, hence in so that one can be remained with between magnetic shoe and rotor core
Quantitative glue, and then improve the retentivity of magnetic shoe, improve the adhesion of magnetic shoe and rotor core.Magnetic shoe is at groove simultaneously
Cross-sectional area at 101 reduces, and can effectively reduce the eddy-current loss of magnetic shoe.
In the present invention one specific embodiment, groove 101 extend perpendicularly to the axial of magnetic shoe body；Certainly, recessed
The bearing of trend of groove 101 also can be parallel to the axial of magnetic shoe body；The bearing of trend of groove 101 also can axial with magnetic shoe body
Angle more than 0 ° and less than 90 °.The i.e. bearing of trend of groove 101 can be any with the angle at the axial right angle of magnetic shoe body,
As long as offering groove 101 on fixing surface, just so that remain with a certain amount of glue between magnetic shoe and rotor core, enter
And improve the adhesion of magnetic shoe and rotor core.
In the present invention one specific embodiment, the edge on fixing surface is run through at the two ends of groove 101.It should be noted that
The two ends of groove 101 also can will be arranged in the centre on fixing surface, this practicality by groove 101 not through the edge on fixing surface
The position of groove 101, shape, length are not limited by type.
In the present invention one specific embodiment, the cross section of groove 101 can be triangle, rectangle or arc, but not
It is confined 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 can be identical
Also can be different.Groove 101 can be spaced apart multiple, it is possible to only arranges one, the quantity of groove 101 and spacing distance,
Should determine with the size of magnetic shoe.The degree of depth of groove 101 does not lays down hard-and-fast rule, can be according to the physical dimension of magnetic shoe, motor
The factors such as rotating speed adjust.
Further, magnetic shoe is when having multiple groove 101, it is preferable that each groove 101 is arranged in parallel, each groove
101 are equally spaced, and the most also can arbitrarily arrange.
The invention also discloses a kind of rotor, including magnetic shoe, magnetic shoe is magnetic shoe disclosed in technique scheme.Due to
Above-mentioned magnetic shoe has the effect above, and the rotor with this magnetic shoe also has corresponding effect, and here is omitted.
The invention also discloses a kind of motor, including rotor, rotor is motor disclosed in technique scheme
Rotor.Owing to above-mentioned rotor has the effect above, the motor with this rotor also has corresponding effect, the most not
Repeat again.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
