Embodiment
Below, describe content of the present invention in conjunction with the accompanying drawings and embodiments in detail.
Fig. 3 is the planar structure schematic diagram of single-phase starting reluctance motor rotor of the present invention.As shown in Figure 3, rotor 10 is included in the iron core 11 in conjunction with mouth 12 in conjunction with the direction formation of rotation axis (not having expression among the figure), and several bar magnets of the formation on every side unshakable in one's determination 11 insert mouth 13, and inserts several bar magnets 14 of insertion in the mouth 13 at bar magnet.And unshakable in one's determination 11 comprise: to the 1st vertical extension of the direction that combines with rotation axis (hereinafter referred to as ' bonding position '), and with the 1st orthogonal the 2nd be that several symmetrical flux shield layers 15 of center constitute.And iron core 11 parts between several flux shield layers 15 become magnetic circuit 16.
In the prior art, the flux shield layer does not form continuous plane and has formed bridge in the centre, at the position that forms bridge the magnetic saturation phenomenon takes place thus, has hindered magnetic induction line to pass.In order to solve above magnetic field saturated phenomenon, the present invention makes unshakable in one's determination 11 to have continuous flux shield layer 15,15a as shown in the figure.This continuous flux shield layer 15,15a have prevented the magnetic saturation phenomenon, and it is smooth more that magnetic induction line is flowed, and have improved the startability of rotor 10.And this continuous flux shield layer 15,15a can save time and expense when making rotor 10.
This flux shield layer 15,15a shared area in the iron core 11 of rotor 10 is big more, represents that iron core 11 areas that the 1st axial magnetic induction line passes reduce, and therefore the magnetic saturation phenomenon takes place on unshakable in one's determination 11 easily.In this, be necessary to adjust the area of flux shield layer 15,15a and the ratio of unshakable in one's determination 11 area (perhaps magnetic circuit 16 areas).And, with area than the same, the width of flux shield layer becomes the smooth factor that flows of magnetic induction line equally.That is, when the width of flux shield layer was too wide, the width of the iron core that magnetic induction line can pass reduced, and is influential for making the 1st direction of principal axis and the 2nd axial magnetic flux density difference maximization if the width of flux shield layer is too little.Thus, be necessary to adjust the ratio of axle in conjunction with the whole width of interval and flux shield layer 15,15a between mouth 12 and 11 outer peripheral faces unshakable in one's determination.
And the part bar magnet in the bar magnet 14 can be kept off flux shield layer 15,15a.This is that when flux shield layer 15,15a were symmetrical for the 1st direction of principal axis, a part of bar magnet 14 can be kept off flux shield layer 15,15a as shown in the figure owing to consider the area of flux shield layer 15,15a.
Fig. 4 a to Fig. 4 c is the planar structure schematic diagram of the rotor region among Fig. 3.
Fig. 4 a is the plane graph of the rotor region in the presentation graphs 3.Shown in Fig. 4 a, rotor 10 to be being that center line is divided into the 1st zone and the 2nd zone with certain angle perpendicular to the 1st on iron core 11 planes of bonding position, and can also divide into the 3rd regional and the 4th zone between the 1st zone and the 2nd zone.Be called the 1st d axle and represent the high-penetration direction of magnetic flux, become the low penetration direction that the 2nd q axle is represented magnetic flux.
Specifically, the both ends that bar magnet in the 1st zone inserts mouth 13,13a ambient magnetic flux screen 15,15a form, make smooth the inserting mouthfuls 13 at bar magnet, flow in the magnetic circuit 16 of the iron core 11 of expansion between the 13a and thus of magnetic induction line (black solid line), be called the high-penetration direction that the 1st d axle becomes magnetic induction line thus.And, the central part of flux shield layer 15,15a is separated by certain spacing around axle combination mouth 12, and be in the 3rd and the 4th zone, bar magnet 14 in the 3rd and the 4th zone and bar magnet insert mouthfuls 13 and do not have magnetic induction line flow under the effect of flux shield layer 15,15a thus, thereby are called the 2nd q axle and become the low penetration direction.
Fig. 4 b is the drawing identical with Fig. 3, shown in Fig. 4 b, rotor 11 among the present invention is poor for the magnetic flux density that increases between the 1st (d axle) and the 2nd (q axle), make the 2nd direction of principal axis neighbouring (promptly, the the 3rd and the 4th zone) the spacing c between the bar magnet 14 less than near the 1st direction of principal axis (promptly, the the 1st and the 2nd zone) spacing between the bar magnet 14 or bar magnet insert the spacing a of mouth 13,13a, b, and minimum in order on the 2nd direction of principal axis, to flow from stator to 11 magnetic induction lines unshakable in one's determination, the magnetic saturation phenomenon takes place on this spacing c.That is, near the bar magnet 14 the 2nd direction of principal axis plays a kind of effect of flux shield layer.
And the both ends of flux shield layer 15 of the present invention are approaching to be that symmetrically arranged bar magnet 14 in center and bar magnet insert mouth 13,13a with the 2nd.Flux shield layer 15 and bar magnet 14 and/or bar magnet insert mouthfuls 13, the gap d between the 13a is a definite value, keep the intensity of rotor 10 when making the 1st axial magnetic flux that the probability minimum of magnetic saturation phenomenon take place on this gap d.Thus, the form at the both ends of flux shield layer 15,15a is corresponding with the form of the inner peripheral surface (face contiguous with the both ends of flux shield layer 15,15a of saying so accurately) of bar magnet insertion mouth 13,13a and/or bar magnet 14.At this moment, gap d is preferably below 0.35mm.
And the spacing e between the outer peripheral face of bar magnet 14 and bar magnet insertion mouth 13,13a and iron core 11 is all identical.
Bar magnet in the 1st and the 2nd zone inserts mouthfuls 13, the width f of the outer peripheral face of 13a is less than or equal to the width g that bar magnet in the 3rd and the 4th zone inserts mouthfuls 14 outer peripheral face.This mainly is smooth on every side the flowing of inserting mouth 13,13a for the bar magnet of magnetic induction line in the 1st and the 2nd zone, and farthest reduce magnetic flux around the bar magnet 14 in the 3rd and the 4th zone, make the 3rd with the 4th zone in bar magnet 14 play and flux shield layer 15, effect that 15a is identical.
Gap while of the bar magnet 14 in area of bar magnet 14 in the 3rd and the 4th zone and width and the 3rd and the 4th zone or have an effect respectively, make the bar magnet 14 in the 3rd and the 4th zone play the effect of flux shield layer 15,15a, the magnetic flux density that increases the magnetic flux density of d axle and q axle thus significantly is poor.
With the direction in conjunction with mouthfuls 12 is benchmark, and bar magnet 14 in the 1st and the 2nd zone and bar magnet insert mouthfuls 13, length h, the i of 13a be greater than the length j of the bar magnet 14 in the 3rd and the 4th zone.This is in the area and width characteristics that influence bar magnet 14 and bar magnet insertion mouth 13,13a, and the area of bar magnet 14 in the 3rd and the 4th zone minimized, and improves the efficient of the area of iron core 11.Can insert mouthfuls 13 at the bar magnet 14 in the 1st and the 2nd zone and bar magnet on this basis, at least one flux shield layer 15a is set between the common tangent line II of 13a inner peripheral surface and the 3rd and the 4th regional that the common tangent line III of bar magnet 14 inner peripheral surfaces.This flux shield layer 15a makes the bar magnet 14 in the 3rd and the 4th zone play the effect of a kind of flux shield layer 15a, and the magnetic flux density that increases the magnetic flux density of d axle and q axle thus significantly is poor.
As above, when flux shield layer 15,15a shared area in rotor 10 iron cores 11 is big, mean that the area of the iron core that can flow at d direction of principal axis magnetic induction line 11 and/or magnetic circuit 16 reduces, therefore on unshakable in one's determination 11, magnetic saturation may take place.Therefore, need to adjust the area of flux shield layer 15,15a and unshakable in one's determination 11 area ratio.In the rotor provided by the invention, preferably in 0.35～0.45 scope, best ratio is 0.39 for the flux shield layer 15 of the entire area on 11 planes unshakable in one's determination relatively, the entire area of 15a ratio.
And for flowing of the smoothness that makes magnetic induction line, the width of flux shield layer also becomes the important factor.That is, if when the width of flux shield layer is too wide, the width of the iron core that magnetic flux passes through reduces, and at the width of flux shield layer too hour, can't make the difference of magnetic flux density of d axle and q axle maximum.Among the present invention, relatively axle in conjunction with mouthfuls 12 and 11 outer peripheral faces unshakable in one's determination between the whole width L1 of flux shield layer 15,15a of width L (that is, the ratio of the closing of the flux shield layer 15 that forms in the width L, each width of 15a=La+Lb+Lc) is in 0.35～0.45 scope.Optimal conditions are that width reaches 0.405 than L1/L.
Fig. 4 c is the partial enlarged drawing of Fig. 4 a.Shown in Fig. 4 c, bar magnet 14 that the center line IV an of end of flux shield layer 15 and/or the other end and flux shield layer 15 are approaching and bar magnet insert mouthfuls 13, the center line V of 13a (divide equally that bar magnet 14 and bar magnet insert mouthfuls 13, the area of 13a the time towards the line of 11 central parts unshakable in one's determination) is on the identical line.This layout be for the magnetic flux that prevents stator by conflicting with flux shield layer 15 in 11 process of flowing unshakable in one's determination, hinder and flow, and make the flowing in unshakable in one's determination and/or magnetic circuit 16 smoothnesses of magnetic flux smoothness.
And as shown in the figure, the width k of flux shield layer 15 is less than or equal to contiguous bar magnet 14 in its two ends and bar magnet and inserts mouthfuls 13, the width m of 13a.Difference between this width is in order to prevent that flux shield layer 15 two ends from hindering flowing of magnetic flux that stator sends, make the magnetic flux smoothness unshakable in one's determination 11 and magnetic circuit 16 in flow.
Specifically, the width n of 41 outer peripheral faces approaching unshakable in one's determination of bar magnet 44 is greater than or equal to the width m of bar magnet 44 near the inner peripheral surface of flux shield layer 15.Particularly, bar magnet 14 and the bar magnet in the 1st zone and the 2nd zone inserts mouth 13,13a has this characteristics.Because this structure, flow into that unshakable in one's determination 1 magnetic flux inserts mouthfuls 13 at bar magnet 14 and/or bar magnet, guaranteed sufficient spacing between the 13a, prevented the magnetic saturation phenomenon, make magnetic flux flows smooth more.And the width m of bar magnet inner peripheral surface reduces, and the spacing 17 between bar magnet 14 and the flux shield layer 15 reduces relatively thus, has prevented to take place on this spacing 17 the magnetic saturation phenomenon.
Fig. 5 is the planar structure schematic diagram of single-phase starting reluctance motor rotor the 2nd embodiment of the present invention.
As shown in Figure 5, within the common tangent line of the inner peripheral surface of the bar magnet 54 of flux shield layer 55 orientation and common tangent line, form a flux shield layer 55a at least perpendicular to bar magnet 54 inner peripheral surfaces of flux shield layer orientation.Rotor 50 have with Fig. 3 in all characteristics of rotor beyond also have other characteristics.Specifically, the iron core 51 of rotor 50 makes the bar magnet 54 in the 3rd and the 4th zone be positioned at flux shield layer 55b.That is, have with the 3rd and the 4th zone in bar magnet 54 between be provided with the identical effect of flux shield layer, flow into magnetic flux between the bar magnet 54 thus under the effect of flux shield layer 55b, can not flow into 51 inside unshakable in one's determination.Thus, the magnetic flux density difference of the magnetic flux density of d axle and q axle will increase significantly.
The characteristics of rotor 10,50 can be reflected in all rotors, can also be used for the part rotor.
Fig. 6 is the speed-torque characteristic curve figure of the rotor among Fig. 3.As shown in the figure, when synchronizing speed is 3600RPM, even (that is, rotor) speed reaches 3600RPM to motor, just can temporarily produce small opposing torque and disappears, and makes torque reach ' 0 ' or near ' 0 '.
