Abstract
An electric generator belongs to the technical field of an electric generator. The utility model is based on the existing electric machine. A rotor (4) and a diamagnetic substance (7) are arranged between an armature winding (3) of the electric generator and a permanent magnet (5). A set of semiconductor rectifier diodes (8) are added on an output circuit. Therefore, the electric generator has the advantage of simple structure.
Description
The utility model relates to a kind of screen set type generator, belongs to technical field of generators.
Existing generator, rotor and the activity of stator do, relative motion make the magnetic flux of armature increase or reduce, and when it sent the alternating current of one-period, rotor and stator will produce two active forces.Promptly when it sent positive half cycle current, armature winding (3) produces a repulsive force did not allow rotor approaching, when it sends negative half-cycle current, produces a pulling force again and does not allow rotor leave, and external force must overcome these two power and just obtain electric energy.Therefore the efficient of generator is not high.
The purpose of this utility model is to overcome the deficiency of prior art, and provides a kind of simple in structure, the screen set type generator that efficient is high.
The utility model is achieved in that the screen set type generator is made up of rotating disk (1), shell (2), armature winding (3), rotor (4), permanent magnet (5), diamagnetic substance (7), bearing (6).Wherein between the armature winding (3) of this generator and permanent magnet (5) are straight, be provided with rotor (4) and diamagnetic substance (7), be added with one group of semiconductor rectifier diode (8) on the output circuit.
Accompanying drawing 2 is a screen set type electric generator structure A-A cutaway view schematic diagram.
Accompanying drawing 3 is a screen set type generator circuit schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing:
The screen set type generator is made up of rotating disk (1), shell (2), armature winding (3), rotor (4), permanent magnet (5), diamagnetic substance (7), bearing (6).Wherein between the armature winding (3) of this generator and permanent magnet (5), be provided with rotor (4) and diamagnetic substance (7).Rotor (4) and armature winding (3) adopt silicon steel sheet to make.Stop the magnetic line of force to adopt lead or bismuth material to make, and rotate with rotor (4) by air gap and the diamagnetic substance (7) that forms the loop.For making armature winding (3) not produce the magnetic force that hinders rotor (4) motion, on output circuit, be added with one group of semiconductor rectifier diode (8).When the screen set type generator was installed, fixed armature winding (3) and permanent magnet (5) make it not do relative motion, and the rotor (4) between armature winding (3) and permanent magnet (5) can freely rotate.
The electricity generating principle of screen set type generator is: manual turntable (1) drives rotor (4) and rotates, blocked the magnetic line of force of armature winding (3) this moment, the magnetic flux of armature winding (3) is changed and reduce, the magnetic flux of variation induces an electromotive force in armature winding (3) coil.When rotor (4) left armature winding (3), the magnetic flux of armature winding (3) increased again, and the magnetic flux of increase induces an electromotive force too in armature winding (3) coil, and sent the alternating current of one-period.
The operation of screen set type generator: when manual turntable (1) drives rotor (4) rotation, send the alternating current of one-period, rotor this moment (4) enters and leaves two motions to armature winding (3).When sending positive half cycle electric energy, rotor (4) enters armature winding (3), and the magnetic flux of armature winding (3) is reduced.By measuring as can be known, because rotor (4) does not produce magnetic field, so the same sex or different in nature magnetic field that armature winding (3) produces all do not produce the motion that repulsive force holds it back to rotor (4).When sending the negative half period electric energy, rotor (4) leaves armature winding (3), the magnetic flux of armature winding (3) is increased, and to pulling force of rotor (4) generation, do not allow it leave, at this moment, semiconductor rectifier diode (8) hinders electric current by armature winding (3), makes armature winding (3) not produce the magnetic force that hinders rotor (4) motion.
The utility model proves and can implement and reach goal of the invention through operation and measurement.
The utility model compared with prior art, have simple in structure, the efficient advantages of higher.
