Background technology
Series motor is mainly made up of stator and rotor part, and stator produces magnetic field by electric current, and rotor also produces magnetic field by electric current and magnetic field induction rotates.But hot-wire coil on stator is under operating state for a long time, produce a large amount of heats, these heats can dispel the heat by stator chip, but the efficiency of depending merely on heat transmission heat radiation is far from being enough, existing a lot of motor arranges fan blade in one end of itself and rotor coaxial, in rotor action, fan blade is dried in the axial direction, reach the object of heat radiation, but because the outer surface of existing stator is all planar structure, in air-supply, air is to outdiffusion, can not effectively evacuate the heat of stator outer surface, the concentrated part of heat is the position between stator and rotor in addition, and space between stator and rotor is less, be difficult to pass into a large amount of air and carry out convection current, add air to outdiffusion, its heat dissipation just cannot guarantee more.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fan housing motor, it is simple in structure, and the space between stator stack and rotor is strengthened, the space of having improved Air Flow, by adding fan housing to converge air-flow directed flow, the air-flow passing through within the unit interval is increased in addition.
Be achieved through the following technical solutions above-mentioned purpose:
A kind of fan housing motor, comprise stator stack, rotor, stator coil and fan blade, described stator stack is by stator chip oriented stack, described stator coil is arranged in described stator lasmination, described rotor is coaxially set in described stator stack, described fan blade is arranged on one end of described rotor, a sheathed fan housing outside described fan blade, and described fan housing and described stator stack are fixed; Two relative arc turn of bilges in order to fixing described stator coil are set in described stator chip, and described arc turn of bilge both sides arrange respectively hides line hole, and the distance between two relative line holes, Tibetan is greater than the distance between two relative arc turn of bilge tail ends.
Preferably, described stator chip is square chip.
Preferably, described line hole, Tibetan comprises arc protuberance and smooth-going portion, and described smooth-going portion and protuberance are connected to form the line hole, Tibetan with cavity.
Preferably, described smooth-going portion is parallel with described stator chip periphery.
Preferably, four jiaos of described stator chip is fillet, and the angle of its fillet is equal to, or greater than 90 degree.
Preferably, between described arc protuberance and smooth-going portion, be fillet, the angle of this fillet is identical with the angle of described drift angle.
The beneficial effects of the utility model are: the line hole, Tibetan that the utility model has smooth-going portion and protuberance formation by design can meet the function of hiding line, simultaneously, the design of the square chip of this novel middle employing, its fillet angle strengthens, and hides the area compact of the utilization in line hole, as the contrast of accompanying drawing 2 and 3, the line hole, Tibetan of equal area, due to its structure difference, make two to hide distance increase between line hole, can effectively increase the volume of Air Flow.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is the structure of traditional stator chip;
Fig. 3 is stator chip structure of the present utility model;
Fig. 4 is wind direction flow schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As Figure 1-4, a kind of fan housing 5 motors, comprise stator stack 2, rotor 1, stator coil 3 and fan blade 4, described stator stack 2 is by stator chip 21 oriented stack, described stator coil 3 is arranged in described stator lasmination, and described stator stack 2 is interior coaxially arranges described rotor 1, and described fan blade 4 is arranged on one end of described rotor 1, at the outer sheathed fan housing 5 of described fan blade 4, described fan housing 5 is fixing with described stator stack 2; As shown in Figure 1, described fan housing 5 is hollow circuit cylinder body structure, and its one end arranges and the identical connection edge of stator chip 21 outward flange structure, links on edge and stator chip 21 fixed bit is all set, and can determine rapidly that position connects when installation.As shown in Figure 3, described stator chip 21 is interior arranges two relative arc turn of bilges in order to fixing described stator coil 3, described arc turn of bilge both sides arrange respectively hides line hole 22, distance B between two relative line holes, Tibetan 22 is greater than the distance C between two relative arc turn of bilge tail ends, due to old-fashioned stator chip 21, it is hidden line hole and presents strip, and the position of its setting extends to inner space, inner space is reduced, the structure of traditional stator chip inside is difficult to change, for conserve space, strengthen two distances of hiding between line hole 22 and can reserve many spaces for air current flow.Compare with the B distance in Fig. 3 as the A distance in Fig. 2, after improving, B distance is greater than A distance.
Preferably, described stator chip 21 is square chip, the fillet at traditional four angles of chip is comparatively straight as shown in Figure 2, the angle of fillet is too little, causes inner available volume less, and therefore outer rim is set to square chip, add the angle of Rouno Cormer Pregrinding Wheel, reduce the radius of fillet simultaneously, make the structure of the whole chip structure that is square, increase inner spatial volume.
Preferably, described line hole, Tibetan 22 comprises arc protuberance and smooth-going portion, and described smooth-going portion and protuberance are connected to form the line hole, Tibetan 22 with cavity.
Preferably, described smooth-going portion is peripheral parallel with described stator chip 21.
Preferably, the drift angle of described stator chip 21 is fillet, and the angle of its fillet is equal to or greater than 90 degree.
Preferably, between described arc protuberance and smooth-going portion, be fillet, the angle of this fillet is identical with the angle of described drift angle.
In above preferred structure, for hide line hole 22 structure as shown in Figure 3, in four angles of stator chip 21 inside, arrange as the line hole, Tibetan 22 of figure, reduce the length in line hole 22, vertical direction Tibetan in figure, increase the length in line hole 22, direction horizontal direction Tibetan in figure, due to the stator chip 21 of square structure, in figure, vertical direction and horizontal direction all increase to some extent and cause inner space to increase, when coordinating above-mentioned line hole, Tibetan 22 structures, it can effectively increase by two of vertical directions and hide relative distance between line hole 22 under the size cases that does not change line hole 22, Tibetan, thereby increase the inner volume that holds air.Between fan housing 5 and stator stack 2, form cavity, in the time that fan blade 4 rotates, in fan blade 4, be formed centrally negative pressure, guiding air flows into from rotor 1 one end, and the path flowing into is from flowing between the space between stator and rotor 1, air flows out from the other end of fan housing 5, can effectively provide heat dissipation by such radiator structure.
The above not imposes any restrictions this novel technical scope, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
