Description
Technical field
This utility model relates to a kind of disk type electric machine stator, particularly to a kind of stator being applicable to Double-rotor disc motor
Winding support, belongs to design of electrical motor manufacturing technology field.
Background technology
At present, both sides are rotor, and centre is that the dual-rotor structure disc type electric machine application of stator is relatively broad.Its common determining
Minor structure has two kinds, and one is that stator core is formed by cold-reduced silicon sheet strip punching winding, slots respectively and be used for laying in both sides
Stator winding, or stator core do not slots, and stator winding is bonded on iron core, has the disc type electric machine effect of this stator structure
Rate is higher, but due to the existence of stator iron yoke, not only wastes material, and increase the volume and weight of motor；Another kind of
It is coreless stator structure, is formed by putting neat hollow winding coil insulant casting solidification.In latter configuration,
The magnetic resistance of main flux is relatively big, and the foundation of air-gap field needs to strengthen the thickness of permanent magnet so that permanent magnet consumption increases, and both increases
Motor volume also causes the motor cost to increase.
Summary of the invention
The purpose of this utility model is that and solves the problems referred to above that prior art exists, and proposes one and is applicable to birotor
The stator winding support of disc type electric machine, improves shortcomings and deficiencies of the prior art.
The technical scheme that this utility model is used is as follows.
The stator winding support of a kind of Double-rotor disc motor, between left rotor disk and right-hand rotation sub-disk, its feature exists
In by several shapes, equivalently-sized and separate stator winding carrier unit around the evenly distributed structure in disc type electric machine axle center
Becoming, the agent structure of the most each stator winding carrier unit is a quadrangular, and bottom surface, two, left and right is fan-shaped or isosceles
Trapezoidal, fan-shaped or isosceles trapezoid bottom surface four edges stretches out respectively and forms eaves shape structure, radially observes in agent structure
The widest I-shaped, constitutes disc type electric machine after the centralized winding of stator winding support assorted that the Steel material of employing magnetic conduction is made
Stator winding assembly.
Eaves shape structure serves the effect of constraint to stator winding coil, simultaneously because there is no stator yoke, and motor
Axial length is less.Space between the stator winding carrier unit that each two is adjacent is fixed as one of Double-rotor disc motor
Pilot trench.
The grooved of stator slot is generally parallel slot and symmetrical, and due to the existence of eaves shape structure, can close notch has
It is beneficial to increase air gap flux density and improve air-gap field waveform, benefits raising motor performance.
Compared with prior art, the beneficial effects of the utility model are: the stator winding carrier unit that permeability magnetic material is made
Agent structure, play support stator winding effect while, reduce again the magnetic resistance of main flux magnetic circuit, permanent magnetism can be reduced
Body thickness, is conducive to shortening disc type electric machine axial length, and the assembling of stator structure and part exchanging is more flexible, coordinate collection
Chinese style winding, stator winding roll off the production line and easier for installation fast.

Detailed description of the invention
Below in conjunction with description figure and embodiment, this utility model is illustrated in greater detail.
Fig. 1 is Double-rotor disc electric machine structure schematic diagram, and stator winding support 1 is constituted with left rotor disk 2 and right-hand rotation sub-disk 3
Rotor agent structure.
Fig. 2 is the axonometric chart of a stator winding carrier unit, and the agent structure of each stator winding carrier unit 4 is one
Individual quadrangular 5, two bottom surfaces of quadrangular 5 are isosceles trapezoid or sector, two, the left and right of quadrangular 5 isosceles trapezoid or sector-shaped bottom
The four edges in face stretches out one fixed width respectively, is formed and has certain thickness (fan-shaped bottom surface) eaves shape structure 6 or (isosceles ladder
Shape bottom surface) eaves shape structure 7, radially observe stator winding carrier unit 4 in I-shaped.
The agent structure quadrangular 5 of stator winding carrier unit 4 and there is certain thickness (fan-shaped bottom surface) eaves shape structure 6
Or (isosceles trapezoid bottom surface) eaves shape structure 7 is made up of permeability magnetic material, while playing support and constraint stator winding effect, again
Reduce the magnetic resistance of main flux magnetic circuit, permanent magnet thickness can be reduced, be conducive to increasing air gap flux density, disc type electric machine can be shortened
Axial length, eaves shape structure can be closed notch to improve air-gap field waveform, benefit raising motor performance.
The change of the agent structure of stator winding carrier unit 4 radially width, will meet and make two adjacent stators windings
The gap of carrier unit constitutes parallel winding space groove, to improve the utilization rate of winding space groove.Equally, eaves shape architecture
After adjustment coiling the to be made assembling of size, winding space groove is well closed.Four inclines of agent structure quadrangular 5
It is fit to do fillet when processing to process, the beneficially direct coiling of winding.
Fig. 3 is the axonometric chart of adjacent two stator winding carrier units, and wherein, adjacent two stator winding carrier units are formed
Closing space is parallel slot for winding 8.
When stator winding rolls off the production line, can directly each through the stator winding carrier unit 4 of insulation processing carry out around
Line, constitutes centralized winding.After coiling completes, by the most evenly distributed for the stator winding carrier unit winding line, then with absolutely
The casting solidification of edge material.
Fig. 4 is the integrally-built axonometric chart of stator winding support.
The foregoing is only a kind of embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
