Abstract
The aim is to To suppress the magnetic imbalance between salient pales. Generator of a magnetogenerator comprising a core (11) having eight projecting poles (T1-T8). The lamp coils (13A-13H) are wound respectively around each projecting pole (T1-T8) and supply electricity to a lamp (L). The charging coils (14E-14H) are wound respectively on the lamp coils (13E-13H). Because electricity usually flows in the lamp coils (13E-13H), even when the battery is fully charged, magnetic imbalance between the projecting poles is thus avoided. Consequently, this magnetic imbalance is reduced without altering the magnetic force and it is thus possible to prevent or reduce electromagnetic vibration noise in use.
Description
The present invention relates to the voltage generation circuit of permanent magnet generator, relate to the improvement project of coil arrangement structure or rather, this coil comprises lamp line circle and charge coil, is installed on the equipment of motorcycle and so on.
Generally, the voltage generation circuit that is used as the permanent magnet generator on the kind equipment that is installed in motorcycle as the star-like voltage generation circuit of a kind of " single-phase halfwave rectifier CT coil form ".This voltage generation circuit comprises: an iron core, and it has the salient pole of some radial arrangement; And some coils on each salient pole respectively.For example two coils are used for charge in batteries (hereinafter this coil will be called " charge coil ", and other coil is used to light the lamp (hereinafter, this coil will be called " lamp line circle ") of motorcycle in the middle of these coils.
In the usual way, a kind of like this voltage generator for example, under the situation of eight salient poles, shown in Fig. 2 (b), on each salient pole, each coil is connected on the lamp such as a headlight (L) as the lamp line circle respectively for six coils; Other two coils are connected on the storage battery (B) as charge coil.Therefore, can utilize storage battery (B) charging of each charge coil from each lamp line circle to lamp (L) power supply.
Yet, in above-mentioned voltage generation circuit, under situation about being full of fully, almost do not have electric current to flow into each charge coil again when storage battery (B).Research is the magnetic potential between each coil and voltage generation circuit in vector field, and shown in Fig. 1 (B), when comparing with other magnetic vector, the comprehensive magnetic vector (A ') related with the 4th salient pole and the 3rd salient pole wanted big (magnetic vector is represented the magnetic potential vector).Reason is as follows, and each lamp line circle is looped around respectively in first to the 6th salient pole each, and their number of turns is identical, makes electric current can only balancedly flow into each lamp line circle.But because electric current can not flow into charge coil, when comparing with the magnetic vector that other coil is associated, comprehensive magnetic vector (A ') wants big.
When each magnetic vector that is associated with first salient pole to the, six salient poles was a unit vector, the comprehensive magnetic vector that is associated with the 3rd salient pole and the 4th salient pole was drawn by following formula (1):
A′＝1.00×Cos22.5°×2.00＝1.85…(1)
Then, the magnetic vector that is associated with the 7th and the 8th salient pole approximately equals zero, and the value (A ') of so comprehensive magnetic vector can be represented the unbalanced numerical value of magnetic.
The magnetic vector that is associated with the first and the 5th salient pole balances each other.The magnetic vector that is associated with the second and the 6th salient pole is balance equally.
As mentioned above, when the imbalance of the magnetic vector relevant with salient pole was bigger, because in the iron core rotary course, yoke and iron core and so on produced vibration, may produce " electromagnetic vibration noise ".
An object of the present invention is to provide a kind of voltage generation circuit that can between each salient pole, prevent or reduce the unbalanced permanent magnet generator of magnetic.
In order to realize this purpose, the invention provides a kind of voltage generation circuit of permanent magnet generator, wherein have:
An iron core is equipped with some salient poles of radial arrangement on plan view thereon; Each lamp line circle is around each salient pole, and these coils are connected on the lamp so that to its power supply; Charge coil is looped around on the salient pole, and this charge coil is connected on the storage battery so that charging;
The voltage generation circuit of permanent magnet generator comprises:
The lamp line circle, they are looped around respectively on all salient poles;
Charge coil, they are on some lamp line circle.
According to the present invention, on all salient poles, charge coil is looped around on some salient pole the lamp line circle respectively; Even make and to be abandoned fully when full that electric current also can flow into all lamp line circles when storage battery.Magnetic vector is corresponding with the number of turns of each lamp line circle.So the energy imbalance of magnetic vector is prevented from.Because the magnetic imbalance is prevented from, so can prevent or reduce electromagnetic vibration noise.
