Abstract
Electromagnetic permanent magnetism united excitation generator, on the rotator surface facing the air gap surface, convex teeth are distributed evenly, and distances between teeth are a pair of polar distance, between the teeth, the permanent magnetism with the same polarity is arranged, on each of the convex teeth, an electromagnetic excitation electric loop is arranged, the electrical power is provided by obverse and reverse amplitude DC source, to produce the plus ot minus Delta, Phi is superimposed on the magnetic flux Phi produced by the permanent magnetism to form the regulation for the generator voltage. The utility model of generator solves the problem that the permanent magnetism generator can not adjust the voltage, and the voltage regulation device with large loss, expensive price and not reliable operation in the motor circuit is not needed.
Description
The utility model relates to permanent magnet generator, more particularly, includes the permanent magnet generator of electromagnetism excited by both.
Existing permanent magnet generator can't be regulated automatically because the magnetic flux itself that permanent magnet produces can not be adjusted, and the voltage that sends under the situation of power fluctuation also fluctuates, and causes terminal voltage to reduce by the generator loading increasing and also can't compensate voluntarily.In order to solve the generating voltage instability problem, conventional way is by the sub-device of outer distribution, utilizes the negative feedback electronic circuit to solve, and the consume of this solution is big, cost is many, and is fragile and regulation loop inertia is big, and degree of regulation is low, uses inconvenience.
The purpose of this utility model provides a kind of architecture advances of permanent magnet generator, forms the generator of permanent-magnetism electromagnetic excited by both, can pressure regulation or voltage stabilizing, have low value, characteristics solid, easy to use.
The utility model purpose reaches by the following technical programs:
A kind of generator of excited by both electromagnet and permanent magnet, have armature portion and excitatory part, it is characterized in that described excitatory part faces on the magnetic conductor surface of air gap each to a double wedge is arranged in the pole span, the width of each double wedge flank of tooth is less than a pole span, winding electromagnetism magnetic is encouraged coil on described each double wedge, when the electromagnetism magnet exciting coil on each tooth was connected mutually and/or is connected in parallel and is drawn out to described excitatory part and makes same current feed described coil outward, all crest top lands presented identical polar; Establish permanent magnet in the groove between every adjacent double wedge, the width of cloth is to magnetization, the polarity unanimity of described whole permanent magnet pole-faces, and permanent magnet pole face width degree equates with the double wedge face width of tooth.
This generator has kept permanent magnet generator engine efficiency height, little, solid, the reliable advantage of heating, but make generator possess the performance of pressure regulation after adding electric excitation, than the way of establishing regulator at generator output end, that is individual governing loop in motor circuit, power is big, expensive, the poor reliability of device, and the utility model generator is the governing loop in the field circuit, exciting power than full excitation is much smaller, and can loss of excitation, can not cause the motor decompression because of strengthening electric current or overload suddenly.Power consumption is little, cost is low, reliable, easy and simple to handle.
Fig. 1 is the motor partial cutaway schematic of expression the utility model first embodiment.
Fig. 2 is the motor partial cutaway schematic of expression the utility model second embodiment.
Describe embodiment in detail below with reference to accompanying drawing, thus can clearer understanding design of the present utility model and advantage.
Fig. 1 is the partial cutaway schematic of expression the utility model first embodiment motor, and in this example, excitatory part 1 is the internal rotor of generator, and its outer generator armature part of placing is a stator 4.11 is magnetic conductor in the excitatory part among Fig. 1, and a plurality of double wedges 12 are offered in the face of stator in its outer round surface trapping crack on the rotor outer circumference surface, and the tooth pitch of double wedge 12 equals a pair of pole span of generator, and face width of tooth is less than half of tooth pitch.On all double wedges 12, be wound with electromagnetism magnet exciting coil 2, electromagnetism magnet exciting coil 2 on each tooth mutually series connection and/or and be unified into the electromagnetism excitation winding, i.e. series connection or in parallel mutually mutually, or the coil of several utmost points is connected into one group, the mutual series/parallel of several coil groups, electromagnetism excitation winding line end is drawn outside the excitatory part, by can forward and reverse luffing DC power supply or short circuit.Establish a permanent magnet 3 in the groove between every adjacent two double wedges, its pole-face width equates with double wedge end face width, and the width of cloth is to magnetization, all permanent magnets face on the end of power generator air gap be the polarity unanimity.
The armature portion of generator is by establishing the teeth groove structure usually like that, the embedded discharge pivot of groove winding, and experimental study finds, the number of teeth is being 2 or 3 better in every pole span on the armature of this routine generator.
During the generator operation of present embodiment, do not power as the electromagnetism excitation winding, all double wedges will become the closed magnetic circuit of permanent magnet 3 magnetic fluxs and present unlike pole with permanent magnet, send voltage V on the armature winding.On the electromagnetism excitation winding, be provided with the plus or minus direct voltage, producing the electromagnetism excitation accordingly leads to ± Δ φ, being superimposed upon and making main flux become φ ± Δ φ on the permanent magnet flux φ, is that V ± Δ V has constituted the adjusting to generator voltage thereby make armature winding bring out existing voltage.When any situation that causes V numerical value to change takes place, control the variation of electromagnetism excitation power supply accordingly, produce adapt ± Δ V, make V ± Δ V=constant, just can voltage stabilizing, perhaps V ± Δ V=ormal weight obtains the result of pressure regulation.
The power supply source of electromagnetism excitation winding can belong to ripe content as for the control method to this power supply in the prior art by obtaining after the generator voltage rectification, repeats no more.
Fig. 2 represents the utility model second embodiment generator part sectioned view.It is the distortion of first embodiment, and different piece only is the shape of cross section of double wedge 12.All still use identical label with the identical part of first example, and no longer are repeated in this description.Present embodiment barrel shaped tooth top forms pole shoe part 13, and its width of tooth magnetic Yoke below the pole shoe is less than the width of pole shoe part.Such double wedge planform, evidence are improved motor performance.
Embodiment of the present utility model illustrates, but should not be limited to this, and this area mean level technical staff can modify it and change in view of the above, and these modifications and change are still within the utility model design scope.
