Abstract
The utility model relates to a waterproof structure for brushless electric motor. The stator subassembly of the brushless electric motor comprising pole pieces, a circuit board, and coils winding around pole pieces is arranged on a base, and a shaft lining is arranged in the middle of the base for fixing and positioning of the stator subassembly. The utility model is characterized in that: a closed zero clearance seal housing formed by closed and consolidated waterproof glue is arranged outside the stator subassembly of the brushless electric motor. The closed zero clearance seal housing enables the brushless electric motor to have remarkable waterproof and moisture-proof effects, and thereby the brushless electric motor of the utility model is more suitable for application in a moist device or environment.
Description
Technical field
The utility model relates to a kind of brushless electric machine waterproof construction.
Background technology
It is little that brushless electric machine has a volume, the advantage of easy drive controlling, and be widely used in the middle of the device or occasion that needs heat radiation industrial, for example: computer, photocopier, devices such as projector, or in the occasion of improper ventilation, and play the radiating effect of air-flow guiding, in addition, brushless electric machine has circuit board, the stator that contains pole piece is set on the circuit board, stator side face winding around, stator center can be pivoted wherein for the rotor axle, and rotor can be turned round at the stator periphery, and can pass through the set blade air-guiding of rotor surface, reach thermolysis, yet brushless electric machine is if be applied in the moist occasion, its stator magnet pole piece, coil and circuit board produce corrosion easily because of making moist, short circuit causes brushless electric machine weak point in useful life and is easy to damage.
The utility model content
The purpose of this utility model is to provide a kind of brushless electric machine waterproof construction, makes the stator module of brushless electric machine obtain splendid waterproof, moisture effect.
For achieving the above object, brushless electric machine waterproof construction of the present utility model, the stator module of described brushless electric machine comprises pole piece, circuit board, and the coil of institute's winding on the pole piece, stator module is arranged on the base, in the middle of the base axle sleeve is set, axle sleeve can supply the sheathed location of stator module, is characterized in: the stator module outside of described brushless electric machine is sealed fixed with marine glue and is formed airtight gapless sealing shroud.
Understand the purpose of this utility model, characteristics and advantage for clearer, preferred embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the stereo appearance figure of the utility model at the sheathed formwork of stator surface;
Fig. 2 is the assembled sectional view of the utility model at the sheathed formwork of stator surface;
Fig. 3 is the utility model is made sealing shroud at stator and circuit board surface an enforcement illustration;
Fig. 4 is that the utility model is produced the schematic perspective view of the gapless sealing shroud of dense applying for the rotor installing at stator and circuit board surface.
Embodiment
At first, please cooperate referring to Figure 1 and Figure 2, wherein, the stator module 20 of brushless electric machine is arranged on the base 10, in the middle of the base 10 axle sleeve 11 is set, the fill orifice 12 that runs through is set on the base 10, axle sleeve 11 can be in addition sheathed for the circuit board 13 of stator module 20, stator module 20 has pole piece, and on pole piece the winding coil.
The utility model is by being provided with dense gapless sealing shroud 40 structures of cohering at stator module 20 side faces, reach excellent waterproof, moisture effect, cooperation is referring to shown in Figure 3, wherein, the utility model design is to be set in stator module 20 outsides with formwork 30, and add hot consolidation in wherein pouring into marine glue, and form dense gapless sealing shroud 40 structures of cohering at stator module 20 side faces, wherein:
The body 31 inner face open side of formwork 30 form first stratum 32 and second stratum 33 that does not wait the circle footpath, and in the body 31 inner accommodation spaces 34 that form, and on the base plate 35 of body 31 closed sides, be provided with towards the three-layered 36 and quadravalence layer 37, the quadravalence layers, 37 end face of accommodation space 34 projections and form a projection 38.
This formwork 30 is sheathed on the stator module 20 of brushless electric machine, can make body 31 open side inner edges be closed in base 10 side faces, first stratum 32 then is resisted against base 10 periphery tops, make whole stator module 20, comprise circuit board 13 wherein, pole piece and coil, and base 10 tops all can be coated fully by formwork 30, marine glue then can be poured into by the fill orifice 12 of base 10, make marine glue dense be bonded in stator module 20, axle sleeve 11 and base 10 side faces, it is coated on stator module 20 side faces by promptly molding dense gapless sealing shroud 40 structures after adding hot consolidation and taking out formwork 30, makes the internal structure of brushless electric machine have splendid waterproof and dampproof effect.
Cooperation is referring to Fig. 4, wherein, behind sealing shroud 40 shaping structures, form step groove 41 on the top, and bearing 52 can be inserted in the step groove 41, step groove 41 and stator module 20 centres sheathed axle sleeve 11 be connected, the axle 51 of rotor 50 can be pivoted wherein.
Therefore, by the detailed description in said structure feature and the making, can know and find out that the utility model provides a kind of dense sealing gapless " brushless electric machine waterproof construction ", it is consolidated into gapless sealing shroud in the stator module outside of brushless electric machine with the marine glue sealing, make brushless electric machine in the operating environment of humidity, can be by sealing shroud and water, effective isolation of aqueous vapor, and allow the damage of can not making moist of brushless electric machine internal structure, so, the utility model design, can avoid traditional effectively and establish the shortcoming of housing, make brushless electric machine be more suitable for being installed in moist device or the environment and used as moisture-proof construction with lid.
