Abstract

The present invention provides a kind of compound disc-type energy-saving motor stator core, stator core is folded sieve by annular silicon steel sheet and is made, subtract whirlpool hole in the heat dissipation that the centre of annular silicon steel sheet is provided with annular array, heat dissipation, which subtracts to be provided with arc between the hole of whirlpool and radiate, subtracts whirlpool seam, and punching has winding coil caulking groove in the inner circle of annular silicon steel sheet and foreign aid.The double winding stator motor made of compound disc-type energy-saving motor stator core, one can replace two conventional motors, with small in size, consumptive material is few, it is light-weight, power of motor density is big, and structure is simple, magnetic vortex can be effectively reduced, and reduces the features such as the motor feels hot leads to electric energy loss.

Description

Compound disc-type energy-saving motor stator core
Technical field
The present invention relates to a kind of brushless permanent magnet motor technical field, specifically a kind of compound disc-type energy-saving motor stator Iron core.
Background technique
That there are weight during production and application is big for traditional brush-less permanent magnetic electricity generator stator core, consumptive material is more, electric current is close The deficiencies of small and complex process service life is short, the especially stator core of ventional disc magneto are spent due to material and design Defect, motor often has when working generates serious magnetic vortex, my presence stayed of magnetic will lead to wire winding fever and increase conducting wire Impedance so that power consumption increase, in order to which radiating motor also wants peripheral hardware heat dissipation ventilation mechanism, cause electric machine structure complicated, cost Increase, thus does not meet current energy-saving and environmentally protective requirements of the times.
Summary of the invention
The purpose of the present invention is to drawbacks described above of the existing technology, provide a kind of high power density, low-material-consumption, The compound disc-type energy-saving motor stator core of magnetic vortex is effectively reduced in low power consuming.
The purpose of the present invention is what is realized by following scheme: compound disc-type energy-saving motor stator core is by annular silicon steel Piece is folded sieve and is made, and subtracts whirlpool hole in the heat dissipation that the centre of annular silicon steel sheet is provided with annular array, heat dissipation, which subtracts, is provided with arc between the hole of whirlpool Heat dissipation subtracts whirlpool seam, and punching has winding coil caulking groove in the inner circle of annular silicon steel sheet and foreign aid.
The compound disc-type energy-saving motor stator core, the width of the winding coil caulking groove of annular silicon steel sheet inner circle outer circle It matches with the diameter of winding coil solid conductor.
The beneficial effects of the present invention are: the double winding stator motor made of compound disc-type energy-saving motor stator core, one Platform can replace two conventional motors, therefore, have it is small in size, consumptive material is few, light-weight, generator power density is big, structure letter List reduces the features such as the motor feels hot leads to electric energy loss,.
Detailed description of the invention
Fig. 1 is the planar structure schematic diagram of compound disc-type energy-saving silicon steel sheets of motor stator core;
Fig. 2 is the A-A of Fig. 1 to section structure diagram;
Fig. 3 is the implementation result figure that compound disc-type energy-saving motor stator core turns to annular generator stator.
Description of symbols: iron core 1;Winding coil caulking groove 2;Heat dissipation subtracts whirlpool seam 3;Heat dissipation subtracts whirlpool hole 4.
Specific embodiment
Compound disc-type energy-saving motor stator core of the invention is further described in conjunction with attached drawing:
As shown in Figure 1-Figure 3, compound disc-type energy-saving motor stator core is folded sieve by annular silicon steel sheet 1 and is made, in annular silicon The heat dissipation that the centre of steel disc 1 is provided with annular array subtracts whirlpool hole 4, and heat dissipation, which subtracts to be provided with arc between whirlpool hole 4 and radiate, subtracts whirlpool seam 3, in ring Punching has winding coil caulking groove 2 on the inner circle of shape silicon steel sheet 1 and foreign aid.
The compound disc-type energy-saving motor stator core, the width of the winding coil caulking groove 2 of annular 1 inner circle outer circle of silicon steel sheet Degree matches with the diameter of winding coil solid conductor.
Embodiment
Compound disc-type energy-saving motor stator core making step is as follows:
Annular stator silicon steel sheet is gone out using conventional stamping method, then sieve is folded into motor annular stator according to regulation thickness, uses Rivet or bolt, which are inserted in heat dissipation and subtract in the hole of whirlpool positioning, is made annular stator core finished product.
The preparation of annular stator winding is to be wrapped in winding coil in annular core inner circle and outer circle line embedding groove by snakelike, The heat dissipation for the annular array being arranged on annular core subtracts whirlpool hole and heat dissipation subtracts whirlpool seam for annular stator winding heat dissipation ventilation and subtracts Magnetic vortex is arrived less, is reduced impedance and is increased electrical efficiency, part heat dissipation subtracts whirlpool hole and is also used to bolt and annular stator disk and prime mover Body is consolidated.
It is the well-known technique of those skilled in the art in addition to the technology contents disclosed in the specification and claims.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its Equivalent thereof.
