Description
Technical field
The present invention relates to a kind of brshless DC motor, the brshless DC motor of a kind of contact pin structure is provided especially.
Background technology
Brshless DC motor has the many merits such as volume is little, rotating speed is high, efficiency is high, easily controllable, is widely used in space flight
The fields such as aviation, track traffic, electric locomotive, precision machine tool.
For oil pump class motor, its working media is typically corrosive liquid, in order to increase the lubricity of bearing,
Such motor designs flow channel for liquids at inner chamber so that working media is full of motor internal.Motor electric interfaces typically uses extraction
Line or adapter.According to lead-out wire, then working media easily leaks into outside motor along lead-out wire gap, to outside structural portion
Part pollutes.According to adapter, then need to use hermetically sealed connector, normally due to adapter is longer, can substantially increase electricity
Machine total length.
Therefore, people are in the urgent need to a kind of brshless DC motor rational in infrastructure.
Summary of the invention
It is an object of the invention to provide the brshless DC motor of a kind of contact pin structure, can effectively solve the problems referred to above.
The technical scheme is that the brshless DC motor of a kind of contact pin structure, including: housing 1, stator 2, rotor 3,
Rear case component 4, bearing 5, circuit board assemblies 6 and rotor sensor 7；Described rear case component 4 is connected with housing 1 afterbody, described fixed
It is internal that son 2 is installed on housing 1, and described rotor 3 is installed on housing 1 and rear case component 4 by bearing 5, described rotor sensor 7
Being fixed on rotor 3 afterbody, described circuit board assemblies 6 is installed on rear case component 4；
Described rear case component 4 includes bonnet 4a, contact pin 4b and glass cake 4c, and described bonnet 4a is reserved with circular hole, described
Contact pin 4b is sintered in the circular hole of bonnet 4a by glass cake 4c, and described glass cake 4c both sides embedding has epoxy resin.
Preferably, by laser carved with mark 8 near the contact pin 4b of described bonnet 4a.
The present invention has a following beneficial effect:
The present invention seals structure by a kind of contact pin, by glass cake by contact pin direct sintering on motor rear cover, and make
Carry out embedding with epoxy resin, reach the sealing effectiveness at lead-out wire, prevent the leakage of working media.Contact pin is used to replace sealing
Adapter, reduces motor length.Carry out the mark of contact pin sequence number at bonnet, improve the accuracy of contact pin wiring.

Detailed description of the invention
Describe the present invention with embodiment below in conjunction with the accompanying drawings.
The brushless DC motor structure of a kind of contact pin structure is as it is shown in figure 1, include: housing 1, stator 2, rotor 3, bonnet group
Part 4, bearing 5, circuit board assemblies 6 and rotor sensor 7；Rear case component 4 is connected with housing 1 afterbody, housing 1 and rear case component 4
Constituting the main support part of motor, it is internal that stator 2 is installed on housing 1, and rotor 3 is installed on housing 1 and bonnet group by bearing 5
On part 4, rotor sensor 7 is fixed on rotor 3 afterbody by nut, and circuit board assemblies 6 is installed on rear case component 4 by screw
On.
Rear case component 4 structure, as in figure 2 it is shown, include bonnet 4a, contact pin 4b and glass cake 4c, bonnet 4a is reserved with circle
Hole, contact pin 4b is sintered in the circular hole of bonnet 4a, motor internal and outside is played sealing function, prevents work by glass cake 4c
The leakage of medium.Due to the insulating properties that glass is good, can ensure that between contact pin 4b and contact pin 4b and bonnet 4a exhausted simultaneously
Edge, prevents motor short circuit in winding.By controlling the thickness of glass cake 4c, it is desirable to the thickness of glass after sintering is less than bonnet thickness,
To carry out the embedding of epoxy resin in glass cake 4c both sides, glass cake 4c is played fixing and protective effect, prevents glass cake
The damage of 4c.Having due to glass cake 4c simultaneously and seal and the ability of insulation, this contact pin type seals structure great abbreviation electricity
Machine structure, decreases the length of motor.
Mark 8 on rear case component 4, as it is shown on figure 3, bonnet 4a outer surface near contact pin 4b, is entered by laser inscription
The mark of row contact pin sequence number, in order to next step carries out lead-out wire welding to contact pin 4b, improves the accuracy of contact pin 4b welding.Due to
Bonnet 4a uses stainless steel material, it is not necessary to carry out surface process, and therefore after laser inscription, bonnet 4a still has antirust, anti-corrosive energy
Power.Use laser writing contact pin mark, the auxiliary component of machining identification class can be avoided, simplify electric machine structure raising motor reliable
Property.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
