Description
Technical field
The present invention relates to direct drive motor rotor technical field more particularly to a kind of band retainer direct-drive permanent-magnetism rotors.
Background technique
Traditional direct drive motor rotor structure, which is typically employed in, directly processes tooth socket in turntable patch permanent magnet surfaces or does not have
Tooth socket, directly attachment magnet structure；
However, above-mentioned direct drive motor rotor structure haves the shortcomings that following, either internal rotor or outer rotor, on turntable
The directly limited length of processing tooth socket processing is only suitable for short permanent magnet, and processing charges is high；If not processing tooth socket directly to paste
Permanent magnet needs separately to do limit tooth socket fixture and mounts, and between permanent magnet if without gap, will lead to the last one patch of permanent magnet
Gap is big under not, or after most what a patch, unevenly, influences motor performance, if there is gap attachment between permanent magnet, rotor exists
In operational process, alternately attachment permanent magnet can loosen for the pole NS, inhale together, motor-field is unevenly distributed, and will lead to rotor failure.
Therefore, existing to overcome in order to solve the above technical problems, it is necessory to provide a kind of band retainer direct-drive permanent-magnetism rotor
There is the defect in technology.
Summary of the invention
It is a primary object of the present invention to propose a kind of band retainer direct-drive permanent-magnetism rotor, it is intended to overcome in the prior art
Defect.
To achieve the above object, the present invention provides a kind of band retainer direct-drive permanent-magnetism rotor, including turntable, bracket component,
And permanent magnet assembly, wherein the bracket component includes circular first support and circular second support, turntable inner wall
Upper end is provided with the first card slot that the first support is set for card, and the lower end of turntable inner wall, which is provided with, sets described second for blocking
The inner wall of second card slot of bracket, the first support and second support has been evenly arranged several tooth sockets, the permanent magnet assembly
It is arranged on the tooth socket.
Wherein, the permanent magnet assembly includes the pole several permanent magnet N and permanent magnet S grade, the pole the permanent magnet N and permanent magnet
S grades of alternatings are attached at the inner wall of the turntable, and the both ends of the pole each permanent magnet N and permanent magnet S grade are fastened on corresponding tooth respectively
On slot.
Wherein, the turntable is tubbiness.
The beneficial effects of the present invention are:
1, compact-sized stability small in size is high, and processing cost is low, easy for installation；
2, keep bracket easy to process, plastic part can be used in sectional production, and precision is high；
3, two retainer angles are staggered, it can be achieved that the attachment of permanent magnet rake angle, optimizes magnetic field structure.
Detailed description of the invention
Fig. 1 is the perspective view of the invention with retainer direct-drive permanent-magnetism rotor；
Fig. 2 is the present invention with the perspective view with retainer turntable in retainer direct-drive permanent-magnetism rotor.
Fig. 3 is explosive view of the band of the present invention with retainer direct-drive permanent-magnetism rotor.
Fig. 4 is the perspective view of bracket component.
The embodiments will be further described with reference to the accompanying drawings for the realization, the function and the advantages of the object of the present invention.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
In view of the limited length of the turntable processing tooth socket processing of current direct drive motor rotor, it is only suitable for short permanent magnetism
Body, and processing charges is high, will lead to permanent magnet without processing tooth socket, the last one is not pasted, or gap is big after most what a patch,
Unevenly, motor performance is influenced, in order to solve the above technical problems, the present invention proposes a kind of band retainer direct-drive permanent-magnetism rotor.
The technical solution adopted in the present invention is mainly: including turntable, bracket component and permanent magnet assembly.Wherein, institute
Turntable patch permanent magnet surfaces both ends are stated with card slot；The bracket component has tooth socket, can be full circle, and also sectional splices,
It is bumped into the both ends card slot of turntable patch permanent magnet surfaces, front and back tooth socket is corresponding, then permanent magnet is alternately pasted into turntable sheet by the pole NS
Face, permanent magnet both ends are stuck on bracket tooth socket, will not be loosened, and a circle rotor structure is formed.The compact stability of structure of the invention is high,
The processing is simple for turntable, does not need processing tooth socket, and permanent magnet assembly does not need separately to match fixture installation, and stent section is easily installed；Tool
Have that structure is simple, it is easy for installation, it is reliable and stable, the features such as save the cost.
Specifically, please referring to Fig. 1 to Fig. 4, band retainer direct-drive permanent-magnetism rotor proposed by the present invention includes turntable 1, bracket
Component 2 and permanent magnet assembly 3, wherein the turntable 1 is tubbiness.
The bracket component 2 includes circular first support 201 and circular second support 201, the upper end of 1 inner wall of turntable
It is provided with the first card slot that the first support 201 is set for card, the lower end of 1 inner wall of turntable, which is provided with, sets described second for blocking
The inner wall of second card slot of bracket 201, the first support 201 and second support 201 has been evenly arranged several tooth sockets, and described
First support 201 is identical with the structure of second support 201, and the permanent magnet assembly 3 is arranged on the tooth socket.
The permanent magnet assembly 3 includes the pole several permanent magnet N 301 and permanent magnet S grade 302,301 He of the pole the permanent magnet N
Permanent magnet S grade 302 is alternately attached at the inner wall of the turntable 1, the both ends point of the pole each permanent magnet N 301 and permanent magnet S grade 302
It is not fastened on corresponding tooth socket.
Compared with prior art, the invention has the following advantages:
1, compact-sized stability small in size is high, and processing cost is low, easy for installation；
2, keep bracket easy to process, plastic part can be used in sectional production, and precision is high；
