Description
Technical field
This utility model is related to motor magnetic shoe field and in particular to a kind of disloyalty is with footpath novel magnetic tile.
Background technology
In the prior art, for the miniature motor of vacuum cleaner, electric tool, small household appliances, scrubbing brush etc., its inside is installed
Common magnetic shoe structure as shown in figure 1, common magnetic shoe connects sides by two arc sides (01,02) of concentric reducing and upper and lower two
(03) form, the head and end of two arc sides (01,02) passes through connection side (03) and is integrally connected, and existing magnetic shoe is all to adopt ferrum
Oxysome is formed by linear cutter, molybdenum filament along two arc sides (01,02) and connect side (03) track walking cutting when, even
The radius of curvature of edge fit (03) is larger, can waste more material during molybdenum filament wire, increases production cost, in addition, common magnetic shoe is each
The thickness at place is equal, and when being arranged in motor, air gap is consistent, and the waveform that air gap flux density is formed is saddle waveform, motor
Performance does not reach most preferably.
Utility model content
In order to solve the fault of construction of common magnetic shoe in prior art, this utility model provides a kind of structure design and closes
Manage, the disloyalty of motor performance can be improved with footpath novel magnetic tile, concrete technical scheme is as follows:
A kind of disloyalty with footpath novel magnetic tile, including interconnective first arc of head and end while and during the second arc, the first arc
While and radius of a circle during the second arc equal, the center of circle on the first arc side is first center of circle, and the center of circle on the second arc side is second center of circle,
First center of circle and second center of circle are in the same horizontal line and misaligned.
As a kind of preferred version of the present utility model, in the middle part of magnetic shoe, thick two edges are thin.
As a kind of preferred version of the present utility model, described compare the first arc while and radius of a circle during the second arc than for 1:
1.
As a kind of preferred version of the present utility model, the distance of center circle between described first center of circle, second center of circle and magnetic shoe
Thickness than for 1:1.
As a kind of preferred version of the present utility model, made using neodymium iron boron.
The beneficial effects of the utility model: compared with prior art, disloyalty of the present utility model with footpath novel magnetic tile only by
First arc while and form during the second arc, their radius of a circle is equal and the center of circle is misaligned, reduces waste material during linear cutter,
Reduce production cost, in the middle part of novel magnetic tile, thick two edges are thin, meet the requirement that magnetic shoe intermediate air gap is little, peripheral air gap is big, in addition,
Compared to the motor using common magnetic shoe, when novel magnetic tile is arranged in motor, the formed waveform of air gap flux density is sine
Ripple, rather than saddle waveform, motor operation steadily, reduces vibrating noise, is easy to commutate, location torque reduces, performance obtains
Improve.
Brief description
Fig. 1 is the structural representation of prior art；
Fig. 2 is structural representation of the present utility model.
In figure, 1 first arc side, 11 first centers of circle, 2 second arc sides, 21 second centers of circle, t thickness, l justifies
The heart away from.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described further:
In description of the present utility model, " " center ", " on ", D score, "left", "right", " perpendicular it should be noted that term
Directly ", the orientation of instruction such as " level ", " interior ", " outward " or position relationship are based on orientation shown in the drawings or position relationship, are only
For the ease of description this utility model with simplify description, rather than instruction or the hint position of indication or element must have specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
As shown in Fig. 2 a kind of disloyalty is with footpath novel magnetic tile, it is solid construction, including head and end interconnective first
Arc when 1 and the second arc 2, the first arc while 1 be inner arc while, the second arc while 2 be outer arc while, the first arc when 1 and the second arc 2 circle
All radiuses are equal, and the center of circle on the first arc side 1 is first center of circle 11, and the center of circle on the second arc side 2 is second center of circle 21, first center of circle 11
In the same horizontal line and misaligned with second center of circle 21, effectively reduce processing waste material.
Disloyalty is thin with two edges thick in the middle part of the novel magnetic tile of footpath, meets the requirement that magnetic shoe intermediate air gap is little, peripheral air gap is big, gas
The formed waveform of gap magnetic flux density is sine wave, rather than saddle waveform, reasonable in design.First arc is when 1 and the second arc 2
Radius of a circle preferably than for 1:1, the distance of center circle l between first center of circle 11, second center of circle 21 and the thickness of magnetic shoe preferably than for
1:1, for the radius of a circle magnetic shoe compared to two arc sides (01,02) of the common magnetic shoe of prior art, has saved production material,
Reduce the complexity of processing.
Disloyalty is made using neodymium iron boron with footpath novel magnetic tile, and its magnetic material is the alloy of neodymium, ferrum oxide etc., also known as magnetic
Steel.Neodymium iron boron has high magnetic energy product and coercivity, simultaneously high-energy-density, and less magnet steel just can produce powerful magnetic
Power, has good mechanical property, is applicable to motor miniaturization, lightweight, the requirement of slimming.
In a word, disloyalty of the present utility model is with footpath novel magnetic tile, reasonable in design, the first arc while and circumference during the second arc
Radius is equal and the center of circle is misaligned, effectively save rapidoprint, reduces production cost, when being arranged in motor, can improve improvement
The properties of motor, thus increase the market competitiveness.
Above content be with reference to specific preferred implementation further detailed description of the utility model it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations, for the ordinary skill of this utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should regard
For belonging to protection domain of the present utility model.
