Abstract
The utility model discloses a kind of novel eccentric magnetic shoe, including iron plate, the first magnet, the second magnet, filler and skeleton are enclosed with the iron plate.Beneficial effect is：After motor makees stator using the novel eccentric magnetic shoe, with it is traditional the motor of stator is made using uniform thickness magnetic shoe compared with, motor noise is small, and commutation is steady, and commutation spark is small, service life length.
Description
Technical field
Electrical heating sciemtifec and technical sphere is the utility model is related to, more particularly to a kind of novel eccentric magnetic shoe.
Background technology
Magnetic shoe is one kind in permanent magnet, is primarily referred to as doing the tiles magnet of stator on magneto.Traditional magnetic shoe
Extrados and the arc core of intrados be to overlap, motor commutation in the course of the work be present in the motor using this uniform thickness magnetic shoe
The shortcomings that spark is big, high noise, and the life-span is low, it is therefore desirable to design a kind of novel eccentric magnetic shoe to replace the uniform thickness in conventional motors
Magnetic shoe, with big, the high noise that solves motor commutation spark, the shortcomings that life-span is low.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of novel eccentric magnetic shoe.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of novel eccentric magnetic shoe, including iron plate, be enclosed with the iron plate the first magnet, the second magnet, filler and
Skeleton.
In order to further improve the practicality of novel eccentric magnetic shoe, the intrados for the magnetic shoe that the iron plate is wrapped to form and outer
Cambered surface decentraction, and arc core is at a distance of 4.2 millimeters.
In order to further improve the practicality of novel eccentric magnetic shoe, the iron plate is soft magnetism iron plate.
In order to further improve the practicality of novel eccentric magnetic shoe, first magnet is rectangular permanent magnet.
In order to further improve the practicality of novel eccentric magnetic shoe, second magnet is cylindrical permanent magnet.
In order to further improve the practicality of novel eccentric magnetic shoe, the filler is magnetic.
In order to further improve the practicality of novel eccentric magnetic shoe, the skeleton is magnetization steel disc.
A kind of novel eccentric magnetic shoe, its making step are：
(1), first magnet and second magnet are put into the skeleton；
(2) the filler sealing, is added into the skeleton；
(3), the skeleton described in iron plate winding environmental sealing.
In said structure, the intrados for the magnetic shoe being wrapped to form due to the iron plate and extrados decentraction, cause magnetic shoe
Thickness be presented thick middle, the thin form in both ends so that magnetic shoe is operated on the maximum hysteresis ring of material everywhere, magnetic
The waveform quality of watt air gap flux density is stable, therefore motor commutation is steady, and commutation spark is small, and noise is low, service life length, and traditional
Uniform thickness magnetic shoe due to be magnetized everywhere degree difference, middle body reaches very big and both sides are gradually small, therefore they are operated in difference
Hysteresis ring on, the waveform quality of air gap flux density is also unstable, causes motor commutation spark big, high noise, influenceing motor makes
Use the life-span.
Beneficial effect is：After motor makees stator using the novel eccentric magnetic shoe, determined with traditional using uniform thickness magnetic shoe
The motor of son is compared, and motor noise is small, and commutation is steady, and commutation spark is small, service life length.
Brief description of the drawings
Fig. 1 is a kind of structural representation of novel eccentric magnetic shoe described in the utility model；
Fig. 2 is a kind of cut-away view of novel eccentric magnetic shoe described in the utility model.
Description of reference numerals is as follows：
1st, iron plate；2nd, the first magnet；3rd, the second magnet；4th, filler；5th, skeleton.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 2, a kind of novel eccentric magnetic shoe, including iron plate 1, the first magnet 2, second is enclosed with iron plate 1
Magnet 3, filler 4 and skeleton 5.
In order to further improve the practicality of novel eccentric magnetic shoe, the intrados and outer arc of the magnetic shoe that iron plate 1 is wrapped to form
Face decentraction, and arc core is at a distance of 4.2 millimeters, iron plate 1 are soft magnetism iron plate, and the first magnet 2 is rectangular permanent magnet, the second magnet 3
For cylindrical permanent magnet, filler 4 is magnetic, and skeleton 5 is magnetization steel disc.
A kind of novel eccentric magnetic shoe, its making step are：
(1), the first magnet 2 and the second magnet 3 are put into skeleton 5；
(2), filler 4 is added into skeleton 5 to seal；
(3), environmental sealing skeleton 5 is wound with iron plate 1.
In said structure, the intrados for the magnetic shoe being wrapped to form due to iron plate 1 and extrados decentraction, cause the thickness of magnetic shoe
Thick middle, the thin form in both ends is presented in degree, so that magnetic shoe is operated on the maximum hysteresis ring of material everywhere, magnetic shoe gas
The close waveform quality of gap magnetic is stable, therefore motor commutation is steady, and commutation spark is small, and noise is low, service life length, and traditional etc.
Thick magnetic shoe is due to the degree difference that is magnetized everywhere, and middle body reaches very big and both sides are gradually small, therefore they are operated in different magnetic
On hysteretic loop, the waveform quality of air gap flux density is also unstable, causes motor commutation spark big, high noise, influences motor and uses the longevity
Life.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change
And improvement, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model requires protection scope
Defined by appended claims and its effect thing.
