First embodiment
Fig. 1, a kind of magneto outer rotor 100 of the present embodiment offer, including shell body 11 are provided and are fixed on
Multiple magnetic shoes 12 of the inner surface of shell body 11.
In the present embodiment, multiple magnetic shoes 12 are along the circumferentially disposed of shell body 11, and multiple 12 points of magnetic shoes are the first magnetic shoe 121
With the second magnetic shoe 122, the first magnetic shoe 121 is spaced apart with the second magnetic shoe 122, and the radian of the first magnetic shoe 121 is more than the second magnetic shoe
122 radian, the ratio for defining the radian of radian and the second magnetic shoe 122 of the first magnetic shoe 121 be K (K=A/B, as shown in figure 1,
A is the radian of the first magnetic shoe 121, and B is the radian of the second magnetic shoe 122), K span is 1.2~1.6.
It is pointed out that the first magnetic shoe 121 and the second magnetic shoe 122 here is the magnetic shoe 12 of two kinds of different magnetic poles, i.e.,
Multiple magnetic shoes 12 have two kinds of magnetic poles (N poles and S poles), and two kinds of pole piece spacings are distributed, so, the first magnetic shoe 121 both can be N
Pole, or S poles, accordingly, the second magnetic shoe 122 and the first magnetic shoe 121 are different.That is, the first magnetic shoe 121 and second
The magnetic pole of magnetic shoe 122 can be chosen according to the demand of user, as long as the magnetic pole of two adjacent magnetic shoes 12 is different.
In the present embodiment, magneto outer rotor 100 also includes magnetic shoe locating rack 13, and magnetic shoe locating rack 13 includes many
The individual locating piece 131 coordinated with magnetic shoe 12, locating piece 131 is located between two adjacent magnetic shoes 12.Locating piece 131 is used to limit
Circumference of the magnetic shoe 12 along shell body 11 is moved, and plays spacing effect.
Motor can produce " counter electromotive force " in the running, counter electromotive force be due to coil it is affected by magnetic fields and to original
The electromotive force that one of electromotive force generation resists relatively.In conventional magneto, the structure of magnetic shoe 12 is using fan loop type, magnetic
Watts 12 as stator a part, air gap is formed between rotor, due to magnetic shoe 12 arc section and rotor it is cylindrical same
The heart, equidistant air gap is formed between the stator and rotor of motor, wherein there is magnetic field, (power in magnetic field is magnetic induction
Intensity, also referred to as magnetic are close).The permanent magnetic multi-stage intermediate frequency generator of conventional even air gap, its approximate flat-topped wave of gas magnetic flux density waveformses is empty
Counter potential waveform also approximate flat-topped wave is carried, harmonic content is big, and irregularity of wave form is high.
For strict meaning, harmonic wave refers to electricity of the frequency contained in electric current for the integral multiple of fundamental wave, typically
Refer to carry out Fourier space decomposition to periodic non-sine electricity, the electricity that remaining electric current for being more than fundamental frequency is produced.
Harmonic content is big, and the influence for generator is more serious.
In order to customer service irregularity of wave form it is high the problem of, in the present embodiment, the radian of the first magnetic shoe 121 and the second magnetic shoe 122
It is different, that is to say, that the radian of two adjacent magnetic shoes 12 is different, specifically, the radian of the first magnetic shoe 121 is more than the second magnetic shoe
The ratio of the radian of 122 radian, the radian of the first magnetic shoe 121 and the second magnetic shoe 122 is K.Because the harmonic wave of back-emf is by gas
The close harmonic wave of gap magnetic is introduced, and the change of the adjacent camber ratio K values of two magnetic shoes 12 is larger to air gap flux density harmonic effects, takes difference
K values, emulate permanent magnetic multi-stage intermediate frequency generator back-emf, the sinusoidal sex distortion of voltage waveform for obtaining back-emf using Fourier decomposition
Rate with K values change curve, as shown in Figure 2.As can be seen from Figure 2, (wide magnetic shoe 12), irregularity of wave form highest, K during K=1
When=1.2~1.6, irregularity of wave form is substantially reduced.Therefore, by changing the radians of adjacent two magnetic shoes 12 (N machines and S poles)
Than K, the voltage waveform sine distortion rate that can make back-emf is substantially reduced, preferred K spans 1.2~1.6 are used as.
Further, as shown in Fig. 2 the ratio for working as the radian of the first magnetic shoe 121 and the radian of the second magnetic shoe 122 is 1.3
When~1.5, irregularity of wave form is in downward trend, belongs to preferable radian ratio range, user can be in K=1.3~1.5
Between choose suitable K values.
Further, magnetic shoe camber ratio K value size directly affects the sinusoidal sex distortion of back-emf voltage waveform in Fig. 2
Rate, considers, as the optional mode of the present embodiment, the ratio of the radian of the radian of the first magnetic shoe 121 and the second magnetic shoe 122
K is 1.4.
The axial section perpendicular to shell body 11 for defining magnetic shoe 12 is cross section, as shown in figure 3, magnetic shoe 12 is transversal
Face includes cylindrical segmental arc 123, inner circle segmental arc 124 and two straightways 125, and cylindrical segmental arc 123 passes through two with inner circle segmental arc 124
Straightway 125 is connected, and two straightways 125 are located at the two ends of cylindrical segmental arc 123 or inner circle segmental arc 124, cylindrical segmental arc respectively
The inner surface of 123 laminating shell bodies 11, center of circle decentraction of the center of circle relative to cylindrical segmental arc 123 of inner circle segmental arc 124, so that
Magneto air gap the distance between (inner stator with magnetic shoe 12) it is uneven.
That is, because cylindrical segmental arc 123 is fitted with the inner surface of shell body 11, relative to the inner circle segmental arc of fan ring
124, the inner circle segmental arc 124 of the magnetic shoe 12 of the present embodiment is bent towards cylindrical segmental arc 123 so that the center of circle of inner circle segmental arc 124 with
Deviate (decentraction) in the center of circle of cylindrical segmental arc 123.Equivalent in outer arc section 123 and the same diametric(al) of inner circle segmental arc 124
On, there is a certain distance between the center of circle of cylindrical segmental arc 123 and the center of circle of inner circle segmental arc 124.
Further, magnetic shoe 12 is bonded in one with shell body 11 by fixing glue, that is to say, that the gluing of magnetic shoe 12 is in outer
The inner surface of housing 11, is easy to the fixation and replacing of magnetic shoe 12.Magnetic shoe 12 can be different from the connected mode of shell body 11
Form, be not limited to the gluing of the present embodiment proposition, user can choose different connected modes according to actual conditions, really
Magnetic shoe 12 is protected to be connected firmly with shell body 11.
Further, as shown in figure 3, the width of the cross section of magnetic shoe 12 is uneven, the width of cross section is along transversal
The length direction in face first reduces to be increased afterwards.Here the cross section of magnetic shoe 12 refers to the thickness of the thickness, i.e. magnetic shoe 12 of magnetic shoe 12,
Along the circumferential from one end of magnetic shoe 12 to the other end of shell body 11, first reduce and increase afterwards.The change of the width of the cross section of magnetic shoe 12
Change so that the air gap of permanent magnetic multi-stage intermediate frequency generator is changed into non-uniform gap (eccentric air gap).Define the center of circle of Inner arc with it is outer
Line between the center of circle of circular arc is eccentric throw h.In other words, eccentric throw h is it can be appreciated that the radius and inner circle of external arc
The difference of the radius of arc, or magneto inner stator external arc radius and magnetic shoe 12 Inner arc radius difference
Value.
Because the permanent magnetic multi-stage intermediate frequency generator of even air gap, the approximate flat-topped wave of its air gap magnetic density waveform, unloaded back-emf
Waveform also approximate flat-topped wave, harmonic content is big, and irregularity of wave form is high.So, in order to change unloaded counter potential waveform, employ partially
Motive gap, makes air gap magnetic density waveform level off to sine wave, so as to effectively suppress unloaded back-emf harmonic wave, table 1 is different eccentric throw h
When counter potential waveform aberration rate contrast.
During the difference eccentric throw h of table 1, the contrast of counter potential waveform aberration rate
| Eccentric throw | 0 | 30mm | 50mm | 70mm |
| Irregularity of wave form | 9.3% | 4.3% | 4.1% | 4.9% |
Drawn by table 1, the eccentric throw h in the center of circle of the center of circle of inner circle segmental arc 124 and cylindrical segmental arc 123 value for 30mm~
During 70mm, influence is smaller when irregularity of wave form is relative to h=0mm, and irregularity of wave form is more or less the same.
Further, according to the test data of table 1, when eccentric throw h is chosen for 50mm, output voltage wave is enabled to become
In sine wave, so as to preferably suppress unloaded back-emf harmonic wave.As shown in figure 4, for wide magnetic shoe 12 and even air gap 3KW forever
Magnetic multistage intermediate frequency generator output voltage wave figure；As shown in figure 5, being the camber ratio K=1.4 of magnetic shoe 12 and eccentric throw h=50mm
3KW permanent magnetic multi-stage intermediate frequency generator output voltage wave figures.By comparison diagram 4 and Fig. 5, when magnetic shoe 12 uses not wide magnetic shoe
When 12 (when two adjacent magnetic shoes 12 have the camber ratio of 1.2~1.6 ratios) and eccentric throw, the voltage of back-emf is enabled to
Waveform sine sex distortion rate is substantially reduced, and harmonic content reduction effectively suppresses back-emf harmonic wave.
The operation principle of the embodiment of the present invention is：
Found by the investigation test of permanent magnetic multi-stage intermediate frequency generator：One is the change of the camber ratio K values of magnetic shoe 12 to gas
The close harmonic effects of gap magnetic are larger, the camber ratio of two magnetic shoes 12 (first magnetic shoe 121 and second magnetic shoe 122) adjacent by changing
K (K spans 1.2~1.6), is substantially reduced with regard to the voltage waveform sine distortion rate that can make back-emf.Two be because uniform
The permanent magnetic multi-stage intermediate frequency generator of air gap, the approximate flat-topped wave of its air gap magnetic density waveform, unloaded counter potential waveform also approximate flat-topped wave,
Harmonic content is big, and irregularity of wave form is high, so, when using eccentric air gap, air gap magnetic density waveform can be changed, be allowed to level off to just
String ripple, so as to effectively suppress back-emf harmonic wave.
