Description
[technical field]
The utility model relates to technical field of motors, and in particular to a kind of novel direct brushless motor.
[background technique]
DC brushless motor passes through the development and technological innovation of many years, very widely used and general in vast household appliances enterprise
Time.Shown in common structure chart 1, including drive end bearing bracket 10, rear end cap 20, in the cavity that drive end bearing bracket 10 and rear end cap 20 fasten, if
It is equipped with circuit board 30, shaft 40, iron core 50, tiles magnet steel 60, is powered by circuit board 30, the iron core 50 and tiles of coil are wound with
60 cooperating of magnet steel, effect of the magnetic field to electric current stress rotate machine shaft 40.
In existing motor, there are two types of the mode of shell is general, one is the drive end bearing bracket 10 of such as Fig. 1, rear end caps 20 to divide
It opens, then carries out assembling assembly, then fix using the buckle fixed form in figure, another is plastic packaging.Assembling mode it is straight
Brushless motor is flowed, leakproofness and stability are always to consider the important indicator of motor performance, often many conventional DCs on the market
Brushless motor can not accomplish really to seal and height is coaxial.The present inventor is directed to existing issue, proposes a kind of novel direct nothing
Thus brush motor, this case generate.
[utility model content]
To solve the above problems, the purpose of this utility model is to provide a kind of novel direct brushless motor, good airproof performance,
Concentricity is high, motor stable working performance.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of novel direct brushless motor, including drive end bearing bracket, rear end cap, shaft, circuit board, magnet steel and wound core, this
The technological improvement point of utility model is, further includes the support plate for having center band through-hole, magnetic vortex inner casing；Support plate is by front end
The cavity that lid, rear end cap are formed is divided into front and rear part；Shaft, magnetic vortex inner casing, magnet steel and wound core are located in front cavity, electricity
Road plate is located in rear chamber, and the bound edge of drive end bearing bracket coats the flange of both support plate, rear end cap together riveted.
The through-hole protrusion of the support plate forms a hole axle.
The wound core set is fixed in hole axle.
The through-hole mounted inside of the support plate has bearing one, and shaft support is on bearing one.
The drive end bearing bracket front is outwardly protruding, and is provided with axis hole, is located in the protrusion in bearing two, shaft support is in bearing
On two.
The magnetic vortex inner casing is the shell of one end open formula, is fixed with a circle magnet steel on its inner wall of open one end, separately
Closed at one end, center has to inner process fixation hole, and set is fixed in shaft.
The magnet steel is monoblock type cyclic structure.
After adopting the above structure, it has the advantage that
1, riveted coats the flange of both drive end bearing bracket, support plate and rear end cap together, and leakproofness increases substantially.Punching press riveting
A monoblock type motor is almost formed after conjunction, is not needed using a fixed screw, motor stabilizing degree improves.
2, by support plate in internal support, so that internal component has obtained support fixed bit, magnet steel and iron core are same
Axis degree is high, and is independently distributed with circuit board, reduces many influence elements, further ensures motor the operation is stable degree, noise
It reduces.
[Detailed description of the invention]
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model preferred embodiment.
[specific embodiment]
Please refer to Figure of description, the utility model is a kind of novel direct brushless motor, be mainly concerned with drive end bearing bracket 1,
Rear end cap 2, shaft 3, circuit board 4, magnet steel 5 and wound core 6, support plate 7, magnetic are vortexed inner casing 8.
The part of shell outside drive end bearing bracket 1,2 motor of rear end cap, the two internal cavity for forming installation after fastening, this is practical
It is novel that cavity is divided into front cavity 91 and rear chamber two large divisions 92 by adding a support plate 7.Circuit board 4 is fixedly mounted on
In rear chamber 92, the signal on circuit board 4 is by that can add lead terminal and external connection on rear end cap 2.Remaining group
Part is substantially all disposed in front cavity 91.
It is that there is a through-hole 71 among support plate 7, to 91 direction of front cavity protrusion, so that intermediate form a hole axle
72, hole axle 72 be it is step-like, inner end is relatively large in diameter, and outer diameter is smaller, and the hole axle 72 at the place of being relatively large in diameter is internally provided with bearing
One 11, wound core 6 is cased on the outside of the hole axle 72 of diameter smaller part.
The front of drive end bearing bracket 1 outwardly protruding 12, and it is provided with axis hole 13, it is located in bearing 2 14 in the protrusion 12, motor
Shaft 3 is supported on support plate 7 and drive end bearing bracket 1 by bearing 1 and bearing 2 14 respectively, and is stretched out except axis hole 13.
It is open shell that magnetic vortex inner casing 8, which is an one end,.Open one end inner wall has fastened ring-type
Monoblock type magnet steel 5.The other end is closing, and centre forms one to inner process fixation hole 81.81 sets of fixation hole in shaft 3,
Entire magnetic vortex inner casing 8 is enabled to cover on the outside of wound core 6, wound core 6 and cricoid magnet steel 5 are aligned, and facilitate work.
The size matching of drive end bearing bracket 1, rear end cap 2, support plate 7,1 bead of drive end bearing bracket form bound edge 15, the bead of rear end cap 2
Flange 16 slightly outwards is formed with the edge of support plate 7, three's stamping riveting is formed into one after assembling, bound edge 15 is by rear end
