For ease of the gathering of magnetic induction line, iron core is " H " shape, and two ends are provided with iron core convexity 15, are two magnetic circuit passages.Coil is concentrated and is surrounded in the middle of the iron core; The cross-sectional sizes of iron core protruding 15 equates with the magnetic conductor cross-sectional sizes or is close.
During work, the outer end of rotating shaft 10 (housing is outer) is connected with external impetus, two magnetic conductors 8,9 about rotating through rotating shaft 10.Alternate conduction is through the flux circuit of last lower core.In Fig. 1, when rotating shaft 10 was rotated 0-90 °, iron core left end convexity 15 was left at left magnetic conductor 8 two ends, breaks off magnetic circuit; Right magnetic conductor 9 two ends are near right-hand member convexity 15, conducting magnetic circuit.At this moment: the magnetic induction line of right magnetic pole 2 is set out by the N utmost point, forms the loop through right magnetic conductor 9 to the right S utmost point; The magnetic induction line of left magnetic pole 1 is set out by the N utmost point simultaneously, gets into right magnetic conductor 9 through upper core 3 and forms the loop through lower core 5 to the left S utmost point.Magnetic flux through coil 4,6 changes, and produces to exchange positive half cycle induced electromotive force.When rotating shaft 10 rotates 90
Zero-180
ZeroThe time, right magnetic conductor 9 leaves magnetic circuit, left magnetic conductor 8 conducting magnetic circuits.At this moment: the magnetic induction line of left magnetic pole 1 is set out by the N utmost point, forms the loop through left magnetic conductor 8 to the left S utmost point; The magnetic induction line of right magnetic pole 2 is set out by the N utmost point simultaneously, gets into left magnetic conductor 8 through upper core 3 and forms the loop through lower core 5 to the right S utmost point; Change has all taken place in size, the direction of the magnetic flux through last lower coil 4,6 during this. Lower coil 4,6 is produced exchange the negative half period induced electromotive force.So constantly rotate magnetic conductor, feasible magnetic flux size and Orientation through upper and lower coil constantly changes in time, produces the alternating electromotive force of inducting that continues in the upper and lower coil.Revolution moving 180
Zero, coil produces a simple sinusoidal electromotive, 360
ZeroCan produce 2.(this example is equivalent to the situation of two pairs of magnetic poles of prior art).Electric current can outwards be exported through binding post 7.Upper and lower coil is when work, and can connect also can parallel connection.Output voltage can be adjusted at double.
In the present embodiment, can be symmetrical set many group magnetic poles, coil (containing iron core) in the housing, like 2 groups, 4 groups, 6 groups, 8 groups lines; Corresponding with it, two magnetic conductors respectively occupy a side, and magnetic conductor is shaped as " I " font or " ten " font, " * " font, " rice " font etc.; Corresponding with it, yoke be shaped as " I " font or " ten " font or " * " font or " rice " font etc.The yoke center is provided with axis hole.
Embodiment 2:
In this example, the magnetic conductor of former rotation is set to translation.That is: magnetic conductor no longer rotates, but on pull bar 10, draws the piston type back and forth movement that pushes away through one, to realize the magnetic circuit of the left and right magnetic pole of conducting.When adopting push-pull fashion translation magnetic conductor, direction is shown in arrow among Fig. 2.
As shown in Figure 2, it is 2 that left and right sides magnetic conductor 8,9 is set, and then opposing parallel is fixed on the pull bar 10; Pull bar 10 is connected with bent axle and power through sliding bearing 13, one ends.Through push-and-pull magnetic conductor 8,9, into and out of between last lower core 3,5 protruding 15, two magnetic circuits at difference conducting iron core two ends.As shown in Figure 2, when the translation to the right of pulling pull bar: left magnetic conductor 8 withdraws from raised position, breaks off magnetic circuit; Right magnetic conductor 9 gets into raised position, conducting magnetic circuit; Otherwise when promoting pull bar translation left: 9 withdraw from, and 8 get into.Reciprocating motion like this, thus reach the effect (see embodiment 1 analyze) of embodiment 1.All the other structures of present embodiment are no longer tired out and are stated basically with embodiment 1.
In this example, magnetic conductor is provided with 1 at least, is cuboid, vertically is fixed on the pull bar 10.During work, a magnetic conductor comes and goes into and out of between last lower core 3,5 two ends protruding 15 two magnetic circuits at alternate conduction iron core two ends.When the translation to the right of pulling pull bar, magnetic conductor conducting iron core right-hand member magnetic circuit; Otherwise when promoting pull bar translation left, magnetic conductor is shifted to iron core left end conducting magnetic circuit.Reciprocating motion like this makes on the iron core 3,5 and forms alternating flux, passes coil 4,6 and produces induced electromotive force.Thereby reach the effect of above-mentioned 2 magnetic conductor translations and the effect of embodiment 1 (seeing that embodiment 1 analyzes).
The above; Be merely the embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.
