Abstract
A brushless DC electric generator with dual salient poles is composed of stator and non-winding rotor. The armature windings and exciting winding are installed on stator. The alternative current (AC) generated by three-phase armature windings are rectified by diode rectifier to output direct current (DC). Its advantages are simple structure, small size, light weight, high power density and reliability, and low cost. It can be used in aviation and spaceflight.
Description
Brushless DC electric generator with dual salient poles of the present invention belongs to the DC generator of electric machinery.
At present no matter domestic and international employed DC generator is civilian, or Aero-Space are used, mainly contain following several: first kind is, the brush DC generator is arranged, and this DC generator is the oldest, and it must dispose brush and commutator, its poor reliability, life-span is short, manufacture process requirement height, cost height, and contaminated environment, maintenance is difficulty also; Second kind is, rotating rectifier formula no-brush synchronous generator, though this generator good reliability, the power-weight ratio height, the rotor structure complexity, and also have diode on the rotor, rotor fault becomes the major failure of this motor; The third is, brush-free claw-pole generator and Lun Teer generator, and the common drawback of these two kinds of motors is, additional air gap is arranged, effectively magnetic circuit is long, thereby the power of motor weight ratio is little, poor performance; The 4th kind is, inductor generator, its major defect are that air-gap flux does not have alternation, and the utilance of magnetic is low, so power-weight ratio is low; The 5th kind is, permanent magnet generator, its major defect are that output voltage can't demagnetization when regulating difficulty and internal short circuit fault; The 6th kind is, switch reluctance generator, and the major advantage of this motor is not have brush, does not also have winding on the rotor, simple in structure, can move by high rotating speed, volume is little, in light weight, but it must dispose converter and rotor-position sensor could be worked, and its reliability is restricted; The 7th kind is, the beginning of the nineties, professor Lipo of Univ Wisconsin-Madison USA waited the double salient pole permanent magnet brushless motor of invention, no matter this motor is to make motor to use, still making generator uses, also all essential allocating power converter and rotor position detector, thereby its structure is still complicated, and there are peculiar those shortcoming and defect of magneto equally in it.
The objective of the invention is to propose a kind of simple in structure, in light weight, volume is little, power density is big, good reliability, the brushless DC generator that cost is low.
Brushless DC electric generator with dual salient poles of the present invention, comprise stator, rotor, there is not winding on the rotor, be with on the stator and concentrate armature winding and excitation winding, armature winding forward series connection on two relative teeth constitutes a phase, three phase windings by diode rectifier circuit, sends direct current, and excitation winding can be contained in stator yoke portion.Its basic functional principle is, when excitation winding is connected with constant current, add mechanical force transmission rotor when making it by the rotation of a certain direction, because the magnetic linkage of every phase armature winding institute linkage changes, winding is with induced electromotive force, when winding is connected with external load, electric power generation then is to the load transmission of electric energy.The magnetic field that armature supply produced is degaussing at preceding half cycle, and second half is for increasing magnetic, because the saturated influence of magnetic circuit, total armature reaction is the degaussing reaction, when load or rotation speed change, can keep constant voltage output by the size of current of regulating excitation winding.
Brushless DC electric generator with dual salient poles of the present invention, owing to not only do not have winding, absence of commutator on the rotor, and the no-rotor position detector, generating also required power converter not during work just is provided with concentrated armature winding and excitation winding on stator, wherein owing to be provided with excitation winding, replaced permanent-magnet structure thereby get, so the structure of this motor is the simplest now, manufacturing process also is the simplest, thereby good reliability, cost is low.Because this rotor tooth enters or leave stator tooth, all produce power conversion so its power density is big, are compared the increase that has at double with switched reluctance machines again, thereby with under the power, volume is little, and is in light weight.So motor of the present invention not only has broad application prospects in civilian occasions such as boats and ships, automobiles, especially has more significance as the electrical convertors and generators in the fields such as Aero-Space and naval vessels.
The present invention has following two accompanying drawings:
The cross section structure schematic diagram of accompanying drawing 1, brushless DC electric generator with dual salient poles.
Accompanying drawing 2, armature winding connected mode schematic diagram.
The stator of brushless DC electric generator with dual salient poles of the present invention (1) forms by silicon steel plate stacking with rotor (2), its basic structure is the 6N/4N toothing, be stator number of teeth 6N, the rotor number of teeth is 4N, as 3 phases, 6/4 toothing, multiple versions such as 12/8 toothing, shown in the accompanying drawing 1 is the schematic cross-section of 3 phases, 6/4 toothing.The stator facewidth is π/6N radian, and the N in the following formula is positive integer 1,2,3,4...... etc.Do not have winding on the rotor, suit is concentrated armature winding (3) on the stator tooth, and excitation winding (4) can be contained in stator yoke portion, also can be sleeved on the stator tooth.The quantity of excitation winding is that the number of teeth of stator is removed by 6, is 6 o'clock as the stator number of teeth, and an excitation winding is set, and when the stator number of teeth is 12, two excitation winding is set, and other by that analogy.The connected mode of stator armature winding as shown in Figure 2, i.e. armature winding forward on two teeth that stator is relative series connection constitutes a phase, forms A-X, three phase windings of B-Y and C-Z, three phase windings send constant DC by diode rectifier circuit again.Motor of the present invention also can constitute single generator by the different connected modes of armature coil on the stator tooth, also can constitute two or more generators.
Claims (1)
1, a kind of brushless DC electric generator with dual salient poles, the rotor (2) that comprises stator (1) and no winding, be set with concentrated armature winding (3) on the stator tooth, three phase windings send direct current by diode rectifier circuit, it is characterized in that also being equipped with on stator excitation winding (4).
