Specific embodiment
It should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this
Utility model.
With reference to Fig. 1 and Fig. 3, a kind of permanent magnet machine rotor of the present utility model, including rotor core 1, tile-shaped magnet steel 2, magnetic
Steel bushing 3.The surface of rotor core 1 offers sipes along the direction around axis, and tile-shaped magnet steel 2 is along around the setting of the direction of axis
In described sipes.Magnetic steel sleeve 3 is cylindrical shape, is sheathed on described rotor core 1, and covers described tile-shaped magnet steel 2.
Magneto of the prior art, the mode that permanent magnet component is fixed on rotor core has varied, and structure is mostly
Extremely complex, lead to the manufacturing process of rotor loaded down with trivial details.This utility model adopts the highly developed shoe of manufacturing process
Magnet steel 2, and tile-shaped magnet steel 2 is arranged at the outer surface of rotor, accordingly, rotor only needs to open up sipes along the direction around axis
For arranging tile-shaped magnet steel 2, avoiding problems in prior art and complexity is carried out to rotor core 1 and sets to arrange permanent magnet component
The situation of meter, particular avoid the situation being arranged at permanent magnet component within rotor core 1.Tile-shaped magnet steel 2 is arranged in rotor
In the sipes on iron core 1 surface, for the laminating type between tile-shaped magnet steel 2 and rotor core 1, this utility model does not do concrete limit
Fixed, various ripe barbola works can be adopted in use as needed.
Tile-shaped magnet steel 2 mutual with rotor core 1 fit on the basis of, this utility model is also in the table of rotor core 1
Surface cover is provided with the magnetic steel sleeve 3 of cylindrical shape, further tile-shaped magnet steel 2 is fixed, and is ensureing the process in high-speed rotation for the rotor
The stability of middle tile-shaped magnet steel 2.This utility model is not specifically limited to the material of magnetic steel sleeve 3, using in can come as needed
Select, in the present embodiment, magnetic steel sleeve 3 is rustless steel magnetic steel sleeve.
In order to meet the needs of magneto power, permanent magnet machine rotor of the present utility model, including plurality of rows of shoe magnetic
Steel 2, multiple rows of tile-shaped magnet steel 2 is arranged in described sipes along the axial direction of motor shaft 6, and that is, above-mentioned rotor core 1 is around the side of axis
To the width of the sipes opening up, it is several times as much as the width of tile-shaped magnet steel 2, therefore can accommodate multiple rows of tile-shaped magnet steel 2.Concrete tile-shaped magnet steel
2 row, needs to determine according to power.In the present embodiment, tile-shaped magnet steel 2 is three rows.
Above-mentioned be designed as along the axle of motor shaft 6 be adjusted up arrange tile-shaped magnet steel 2 quantity, similar, according to permanent magnetism
The needs of power of motor, can also be adjusted up arranging the quantity of tile-shaped magnet steel 2 along motor shaft 6, that is, around the side of axis
In above-mentioned each row's tile-shaped magnet steel 2, multiple tile-shaped magnet steels 2 are arranged in order along motor shaft 6 around the direction of axis, multiple watts
Shape magnet steel 2, around one week of full rotor core 1, has certain gap between adjacent tile-shaped magnet steel 2.
The slot effect of magneto, can affect the efficiency of motor.When motor stator adopts tooth slot structure, tooth is used for guiding
The magnetic line of force, reduces magnetic resistance, and groove is used for inlaying winding and interlinking with the magnetic line of force in tooth, and tooth and the different magnetic conductivity of groove make rotor
Have, in diverse location, the magnetic line of force that quantity do not wait, in the position of the quasi- stator tooth of pole pair, ferromagnetic attracting so that hinder motor
The rotation of rotor, just creates slot effect.As can be seen here, the slot effect of magneto is to be produced by its Basic Design
, therefore can not possibly be completely eliminated.But it is because that slot effect can cause the starting reactance of motor so that motor operation is unstable
Fixed, efficiency reduces, so the design of magneto each several part should be optimized, to reduce the impact of slot effect as far as possible.
In the present embodiment, including three row's tile-shaped magnet steels 2, each row's tile-shaped magnet steel 2 has polylith tile-shaped magnet steel 2, Mei Yipai again
The gap being formed between adjacent tile-shaped magnet steel 2 in tile-shaped magnet steel 2, shape between adjacent tile-shaped magnet steel 2 in another row's tile-shaped magnet steel 2
The gap becoming does not line up in the axial direction.This design makes the magnetic pole on rotor produce certain inclination with respect to motor shaft 6, turns
Tiltedly pole is a kind of method reducing slot effect to son.The sineization of the winding counter electromotive force that skewed-rotor causes will increase electromagnetism
Torque ripple, selects suitable poles oblique angle to be effectively to suppress the key of slot effect.Therefore, this utility model is using
In, also should determine the size of each row's tile-shaped magnet steel 2 offset angular according to specific needs.Using this design it is possible to effectively subtract
The slot effect of small machine, so that motor smooth pivotal, reduces the vibrations of motor.
The rotor of magneto, in running, due to the non-uniform mass with respect to motor shaft 6 axis, can produce
The certain centrifugal force of life, can produce certain moment of inertia, make rotor have certain vector.This unbalanced power can be drawn
Play the vibrations of rotor, produce noise, and accelerate the isostructural abrasion of rotor bearing, have a strong impact on performance and the life-span of motor, because
Imbalance in this running of this rotor needs corrected ability normal work.
With reference to Fig. 2, this utility model to subtract trochantinian vector using dynamic balancing clay 4.Dynamic balancing clay 4 is arranged on
State two edges of rotor surface sipes.This design can effectively reduce the vibrations causing because of rotor unbalance dynamic.
With reference to Fig. 2 and Fig. 3, corresponding with the setting of above-mentioned dynamic balancing clay 4, this utility model takes measures to dynamic simultaneously
Balance clay 4 is fixed, i.e. the two ends shaping in magnetic steel sleeve 3 has chamfering or fillet 5, so that this chamfering or fillet 5 cladding is located at
The dynamic balancing clay 4 at sipes edge.Therefore, the diameter of magnetic steel sleeve 3 and length need to be adapted with rotor diameter and sipes width,
Meet the fixing tile-shaped magnet steel 2 and cladding needs positioned at the dynamic balancing clay 4 at sipes two edge simultaneously.
This utility model further relates to a kind of magneto, including motor shaft, stator and permanent magnet machine rotor；This Permanent Magnet and Electric
Machine rotor is permanent magnet machine rotor of the present utility model, including rotor core, tile-shaped magnet steel and magnetic steel sleeve；Rotor core is sheathed
In motor shaft, the surface of rotor core offers sipes along the direction around axis；Tile-shaped magnet steel sets along the direction around axis
It is placed in described sipes；Magnetic steel sleeve is cylindrical shape, is sheathed on described rotor core, and covers described tile-shaped magnet steel.According to need
Want, rotor and motor shaft 6 can be cast in integration.
In sum, the utility model proposes permanent magnet machine rotor, tile-shaped magnet steel is fixed on the mode phase of rotor core
To simple, manufacturing process simplicity；Reduce the vector of rotor by dynamic balancing clay；Each row's tile-shaped magnet steel staggers certain angle
Degree, makes rotor magnetic pole tilt, reduces the slot effect of motor；Magnetic steel sleeve simultaneously works as solid to tile-shaped magnet steel and dynamic balancing clay
It is set for using.
