Abstract
A constant-DC electric generator technically features that the movement of armature is always cutting the magnetic force lines perpendicularly. Its advantages are simple structure, low cost and stable current or voltage.
Description
This invention belongs to the electromagnetic induction knowledge in the physics.
What use at present all is alternating current generator, and DC generator is that alternating current generator adopts commutator to achieve the goal, and constant current is additional on this basis rectifier (having the silicon rectifier of employing to obtain constant dc current in modern technologies).
The DC generator cost of making is higher at present, and consumption copper is more, and commutator is made more complicated, safeguards also harder to tackle.And constant dc current is quite extensive in actual applications.
Learn according to electromagnetic coupling theory knowledge: conductor will inevitably produce induced electromotive force when doing cutting magnetic line movement; Again according to relevant experimental data, can design the not only simple but also quite practical novel constant DC electric generator shown in (Fig. 1).This generator has not only enriched the content in the electricity, and to have overthrown that magnetic flux in the law-closed circuit of (two physics of senior middle school, electromagnetic induction one chapter) in the physical textbook changes be to produce faradic condition.Because constant DC electric generator is an armature doing the motion of the perpendicular cuts magnetic line of force, can't changes with magnetic flux in the closed circuit and explain.
Constant DC electric generator is proved very simply, and experiment only needs two blocks of magnet.A circular wheel formula conductor, conductor wire, universal meter just can be realized purpose.
The advantage of constant DC electric generator:
One, simple in structure, easy to manufacture, cost is low.Current/voltage is stable.The most suitable microgenerator.
Two, several generators can connect arbitrarily (or in parallel).Series connection can improve voltage, increases power output (this is identical with the series battery principle).And direct current machine is in parallel only at present, can't connect.
Three, the positive effect of constant DC electric generator has been to fill up a blank in the Electrical Motor.
The drawing explanation:
The structure of constant DC electric generator: both sides are circular magnet, are a circular armature between two magnet, and conductor wire connects the armature outer round edge edge and the armature center of circle respectively.
Fig. 1: the both sides magnetic pole is a stator, and circular armature is a rotor, and conductor wire connects the armature outer round edge respectively along on brush and the armature center of circle conduction axostylus axostyle.
Fig. 2: Fig. 2 is the front elevation of circular armature between two magnetic poles.
Fig. 3: the both sides magnetic pole is a rotor, the right magnet hollow (any magnet is all right), and circular armature is a stator, and one of conductor wire connects the circular armature edge, and the other end is passed the right magnetic blow out centre and is connected the armature center of circle.
Fig. 4: magnetic pole and armature are rotors, and do motion in the other direction simultaneously.The right magnet is hollow, and conductor wire connects armature circle outer edge brush respectively and passes on the armature circle core shaft of magnet.
The operation principle of constant DC electric generator:
Fig. 1: armature is rotary: when circular armature during along the arrow direction shown in the figure (magnetic pole is fixed), armature is promptly done the motion of the perpendicular cuts magnetic line of force.According to " right-hand rule ", electric current flows to the armature center of circle through the circular armature radius outside justifying by oneself, flows to conductor wire through circle core shaft.
Fig. 3: magnetic pole is rotary: when magnet during along the arrow direction shown in the figure (armature is fixed), armature is being done the motion of the perpendicular cuts magnetic line of force equally.Justify by oneself according to " right-hand rule " electric current and outer to flow to the armature center of circle through the circular armature radius, cross magnetic blow out centre through center of circle conduction pavilion and flow to conductor wire (magnetic pole rotation, if why armature can not resemble to design as Fig. 1 armature Fig. 1 design, armature is being done cutting magnetic line movement simultaneously with the lead that is connected the armature center of circle, according to " right-hand rule ", armature, electric current are justified the outer center of circle that flows to by oneself; The lead that connects the center of circle so also produces the current direction center of circle, so just produces convection current mutually).
Fig. 4: move toward one another formula: when magnet and armature during simultaneously in opposite directions along the arrow direction shown in the figure, armature is being done the motion of the perpendicular cuts magnetic line of force, according to " right-hand rule ", electric current is justified external diameter circular armature radius by oneself and is flowed to the armature center of circle, crossing magnetic blow out centre through circle core shaft flows to conductor wire (move toward one another: according to the motion in the kinematics is relative principle, so, this just equals armature movement speed and is doubled.So, power output has been exactly original four times.Foundation: electrical power=voltage * electric current, the movement velocity of the conductor length * conductor of electromotive force=magnetic flux density * cutting magnetic line, electromotive force=open circuit voltage, electric current=voltage ÷ resistance.Under the constant situation of other condition, the movement velocity of conductor doubles.Electromotive force just doubles, and also just equals voltage and is doubled, and corresponding electric current also is doubled, and twice and original voltage multiply by twice and original electric current so, and electrical power has been original four times.At present, generator under certain conditions, when reaching certain rotating speed, the speed that wants to double again is very difficult, and adopts move toward one another to reach this purpose, is easy to many technically).
