Description
One: technical field:
The present invention relates to a kind of alternator without Ampere force, particularly threephase alternator.
Two: background technology:
The principle of synchronous generator is from electromagnetic induction phenomenon, and electromagnetic induction phenomenon has varied, and the electromagnetic induction phenomenon that Fig. 1 represents is the basic principle of synchronous generator, produces induced current among the coil N when coil N rotates.By law of electromagnetic induction induced current is to be produced by the magnetic flux change that also has uniform magnetic field B to pass the area S that coil N surrounded that ab limit among the coil N and cd limit " cutting " magnetic line of force produce.By Ampere's law, when coil N in uniform magnetic field B around fixing axes O O " when rotating; be subjected to the effect of Ampere force (magnetic field is to the active force of current carrying conductor) among the coil N in uniform magnetic field B by the induced current on ab limit and cd limit, the effect of Ampere force produces brake torque to rotating coil N; By Lenz's law, the induced current in the revolving coil N also produces brake torque in the change that abcd surrounds the magnetic flux of magnetic field resistance the causing induced current that produces on the area S to revolving coil N again.From the above experiment electromagnetic induction phenomenon of Fig. 1 as can be seen, the effect of existing Ampere force also has induced current to produce the effect in magnetic field.
The operation principle of transformer is from the electromagnetic induction phenomenon different with the principle of synchronous generator, Fig. 2 represents the induced current in the loop A, change by the current strength among the current-carrying coil B causes, when telegraph key K plate is disconnected, by the magnetic flux minimizing of loop A, according to Lenz's law, the magnetic direction of induced current should make the magnetic flux by loop A increase in the loop A, again according to right-hand screw rule, and sense of current, if B looks to A from coil, should be counter-clockwise direction.The operation principle of Here it is transformer.From the above experiment electromagnetic induction phenomenon of Fig. 2 as can be seen, belong to the electromagnetic induction phenomenon of ampere-force-free effect.
Three: summary of the invention:
The purpose of this invention is to provide a kind of ampere-force-free (active force of the 1 pair of stator coil 6 in rotor field) alternating current generator, the operation principle of this generator is similar to the operation principle of transformer, the operating efficiency of the transformer ratio of input power (power output with) is up to 98%, mainly be because the operation principle of transformer has been utilized the electromagnetic induction phenomenon of the ampere-force-free effect that image pattern 2 explained, do not have the effect of Ampere force during transformer work.The alternator without Ampere force that utilizes this principle to make equally, the inhibition of Ampere force in the time of also can eliminating generator for electricity generation, thus reach the purpose that improves generating efficiency and save the energy.The main cause of traditional synchronous generator engine efficiency low (although synchronous generator engine efficiency height relevant with multiple factor) is, operation principle is used is that the effect of the image pattern one existing Ampere force of being explained also has induced current to produce the electromagnetic induction phenomenon of the effect in magnetic field.
Alternator without Ampere force is the same with synchronous generator to have invertibity, also can make motor and use.The rotor magnetic pole number of different is synchronous generator is 1: 1 with the ratio of stator magnet number of poles, and the ratio of the rotor magnetic pole number of alternator without Ampere force and stator magnet number of poles is 2: 3.The frequency f of the electromotive force that sends when we know generator for electricity generation is relevant with the magnetic pole logarithm p of rotor speed n and generator, and the magnetic pole logarithm p of alternator without Ampere force refers to the rotor magnetic pole number.The weakness of alternator without Ampere force is: need to strengthen strict magnetoelectricity stream and strengthen strict magnetic magnetic field intensity; The time spent of stator coil 6 increases to some extent around the home.Beneficial effect is: the operation principle of generator changes the behind efficiency ratio of input power (power output with) height, can reach 85%-90%; The utilance height of stator winding, a coil can form an independently magnetic pole, and mutual inductance is little between the phase winding.
