Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Multichannel output generator of the present invention as shown in Figure 3, it is similar substantially to existing generator Structure shown in Figure 1.It comprises a shell 1, and the central axis location arrangements in the shell 1 has an armature spindle 5, and armature spindle 5 rotatably is fixed on the bearing 4 at shell 1 two ends.Be with a rotor 6 on the armature spindle 5, the outer surface of rotor 6 is coated with rotor permanent magnet 7, and rotor permanent magnet 7 can adopt rare earth (or magnet steel) permanent magnetic material.
Being with the difference of existing generator shown in Figure 1, being fixed with two stators on the shell 1 of the present invention, is first stator 21 and second stator 22, and these two stators are the axis direction transverse arrangement of turbo along armature spindle 5 basically.First stator 21 and second stator 22 can be regarded as and the stator among Fig. 12 be divided into longitudinally two parts form.Be respectively arranged with winding coil 3 on first stator 21 and second stator 22, winding coil 3 comprises one or more winding.Because first stator 21 separates setting with second stator 22, so just cut off the flux path of the winding coil 3 on these two stators basically, avoided their mutual electromagnetic induction to a great extent.
But according to the characteristic of electromagnetic propagation, the part magnetic line of force of the winding coil 3 on first stator 21 and second stator 22 also might form flux path by rotor 6.
Therefore, as shown in Figure 4, as a further improvement on the present invention, corresponding to two stators 21 and 22, the coaxial the first rotor 61 and second rotor 62 of being equipped with at intervals successively on the armature spindle 5.First stator 21 and the first rotor 61 positioned opposite, second stator 22 and the first rotor 62 positioned opposite.So just further cut off the flux path of winding coil 3, thereby further reduced the electromagnetic induction influence between them.In order to obtain better effect, between the first rotor 61 and second rotor 62, also be filled with non-magnet material 8.
In order to further specify effect of the present invention, Fig. 5 shows the principle schematic of the generator of Fig. 4, therefrom can more clearly understand the distribution of winding on the stator.As shown in Figure 5, the two statodynes of this birotor comprise first stator 21 and second stator 22, correspondingly also comprise the first rotor 61 and second rotor 62.First stator 21 is provided with three phase winding A and three phase winding B, and the voltage output of these two winding A and B behind common mode filtering, is exported two groups of separate direct voltages again through PWM modulation voltage stabilizing.These two groups of direct voltage sources both can use separately, and the branch two-way that also can be chained together output is used.Second stator 22 is provided with three phase winding C and single-phase winding D.Three phase winding C export one group of three-phase alternating voltage, and provide a burning voltage for above-mentioned PWM modulating voltage stabilizer after the wherein two-phase of three phase winding C process common mode filtering and the AD/DC modulation voltage stabilizing.Individual event winding D exports a single phase alternating current (A.C.) voltage.
In an embodiment of winding shown in Figure 5, winding A and winding B are that load is not high to the required precision of this voltage for the load that needs high power, big electric current provides voltage, and the electromagnetism rubbish that is produced by these two windings is bigger.Winding C and winding D are that the load for low-power, little electric current in the needs provides voltage, and this voltage of load request has higher precision.Therefore, when being arranged in winding A and B and winding C and D on two stators, a large amount of electromagnetism rubbish that winding A and B produce just can not have influence on winding C and D by magnetic circuit, thereby guarantee the stability and the desired precision of winding C and D output voltage.
Though only the generator with two stators and/or two rotors illustrates the present invention in embodiment, but, according to principle of the present invention, one of ordinary skill in the art can not need to obtain to comprise the more generator of multiple stators and rotor through performing creative labour, these rotors and stator are the sugarcoated haws string data and are installed on the armature spindle, thereby avoid electromagnetic interference so that winding is arranged on the different stators.For example, first stator 21 of Fig. 5 can be further divided into two stators, be used for arranging respectively winding A and winding B, further avoid mutual electromagnetic interference between winding A in the system and the winding B.
