Abstract

The invention disclosed a magnetic control generator, which comprises a housing, two set of magnetic poles and two coils are provided in the housing, the poles are at both sides of the coils, a magnetizer are provided between each set of magnetic poles, the magnetizer is sleeved on a rotary shaft, the two magnetic control slices vertical to each other are fixed on the shaft. electrode terminals of the coils are outside of the housing, the rotary shaft is provided on the housing, because the inventive rotary part mainly is the magnetic control slice, made of thin ferro magnetic material, the invention has simple structure, small volume and light quality. In operation, small eddy current and low temperature are provided. So, comparing with current heavy rotor of generator, In structure of the invention, the coils and magnetic poles are stable, current may be outputted directly, electric brush are unnecessary, and the safe operation of motor can be ensured.

Description

A kind of magnetic control generator

Technical field

The present invention relates to mechanical generating apparatus, particularly adopted the method for controlling magnetic field, make through the coil flux amount to change, produce faradic mechanical device.

Background technology

It is stator (rotor) that present generator adopts coil usually, and magnetic pole is rotor (stator).It is big to have energy output, advantages such as manufacturing technology maturation.Shortcoming is, rotor quality is big, and volume is big.When work, the eddy current of generation is big, and temperature is high.

Summary of the invention

The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of rotor structure simple, produce the less a kind of magnetic control generator of eddy current.

The present invention realizes through following technical scheme:

A kind of magnetic control generator includes housing, is provided with magnetic pole and coil in the housing, and the electrode tip on the coil is positioned at outside, and housing is provided with rotating shaft, and being positioned at the housing internal fixation in the rotating shaft has the control magnetic sheet, and this control magnetic sheet is between magnetic pole and coil; Said coil is two; The iron core of this coil is I-shaped, and said magnetic pole is two groups and is positioned at the both sides of coil, and wherein a of iron core, b end are corresponding to N, the S end of magnetic pole; The c of iron core, d end are held corresponding to N, the S of magnetic pole, and said control magnetic sheet is two and is vertically fixed in the rotating shaft each other.

Advantage of the present invention is:

Because rotating part of the present invention mainly is the control magnetic sheet, it is to be processed by thin ferrimagnet, and is simple in structure, and light weight, volume are little.When work, the eddy current of generation is little, and temperature is low.Therefore, for the rotor of present generator heaviness.In structure of the present invention, coil and magnetic pole are fixed, and electric current can directly be exported, and need not use brush, can guarantee the generator safe operation.

Embodiment

Embodiment 1: magnetic control generator as shown in Figure 1, include housing 7, and be provided with magnetic pole 3 and coil 4 in the housing 7, the electrode tip 6 on the coil 4 is positioned at housing 7 outsides, and housing 7 is provided with rotating shaft 1, and rotating shaft 1 is provided with bearing 2 between housing 7.Said coil is two, and said magnetic pole 3 is two groups and is positioned at the both sides of coil 4, and two groups of magnetic pole 3 same sexes are relative, are provided with magnetic conductor 8 between every group of magnetic pole 3, and magnetic conductor 8 is enclosed within the rotating shaft 1.Be fixed with control magnetic sheet 5 in the said rotating shaft 1, said control magnetic sheet 5 is two and is vertically fixed on each other in the rotating shaft 1 that two control magnetic sheets 5 are between magnetic pole 3 and coil 4.

During work, the outer end of rotating shaft 1 is connected with external impetus, rotates control magnetic sheet 5 through rotating shaft 1, to the shielding that hockets of coil 4 right ends.Shown in Figure 15 of the controlled magnetic sheets of the magnetic line of force of the right-hand member N utmost point are dredged when coil 4 right-hand member conductively-closeds, and the magnetic line of force that leads to coil 4 is intercepted; Left end is open simultaneously, and the magnetic line of force of the left end N utmost point passes coil 4 left ends, and the magnetic flux through coil 4 is changed, and produces induced current, left end conductively-closed thereupon; Right-hand member is open, and the magnetic line of force of the right-hand member N utmost point passes the coil right-hand member, and the magnetic flux through coil 4 is changed, and change has also taken place relative direction, and coil 4 produces induced current in the other direction.The magnetic sheet 5 of rotation control so constantly, feasible magnetic flux size and Orientation through coil 4 all constantly changes, and produces the induction alternating current that continues in the coil 4, and electric current can outwards be exported through binding post 6.Upper and lower two groups of coils 4 Be Controlled generating simultaneously, two coils 4 can be connected also can parallel connection.Magnetic conductor 8 adhesives are fixed on magnetic pole 3 afterbodys, are used for conducting magnetic field.For making shield effectiveness better, control magnetic sheet 5 adopts the multilayer ferrimagnet synthetic.According to circumstances, rotary type control magnetic sheet in like manner becomes flatly moving type control magnetic sheet.

Embodiment 2: magnetic control generator as shown in Figure 2, and the structure of present embodiment and embodiment 1 are basic identical, and its difference is that the iron core of said coil 4 is I-shaped, and the number of magnetic poles of so relative coil 4 has increase.Said magnetic pole 3 is two groups and is positioned at the both sides of coil 4; Wherein a of iron core, b end are held corresponding to N, the S of magnetic pole 3; The c of iron core, d end are held corresponding to N, the S of magnetic pole 3, and said control magnetic sheet 5 is two and is vertically fixed on each other in the rotating shaft 1 that this control magnetic sheet 5 is between magnetic pole 3 and coil 4.

During work, rotate control magnetic sheet 5, to the shielding that hockets of coil 4 iron core the right and lefts, when the conductively-closed of the right, by the N S utmost point that extremely directly leads, the magnetic line of force that leads on the right of coil 4 iron cores is intercepted the magnetic line of force on the right through control magnetic sheet 5.Simultaneously the left side is open, and the magnetic line of force of left side magnetic pole 3 is set out by the N utmost point, through iron core a end from coil " below " get into its inside, go out from above, get back to the S utmost point through the b end.In moment, the magnetic flux through coil 4 is changed, produce induced current.Left side conductively-closed thereupon; The right is open, and the magnetic line of force of the right magnetic pole is set out by the N utmost point, through iron core c end from coil " above " get into its inside, go out from below, get back to the S utmost point through the d end.Magnetic flux through coil 4 is changed, and with former in the opposite direction, coil 4 produces induced current in the other direction.So constantly rotate the control magnetic sheet,, direction big or small through the magnetic flux of coil 4 all changes continuously.Make coil 4 produce the induction alternating current that continues.Up and down two groups of coils 4 to the time Be Controlled generating, but two coil 4 series and parallels.Electric current is outwards exported through binding post 6.Present embodiment, it is simple to have a rotating part, and control magnetic sheet armoured magnetic field is effective, the advantage that generating efficiency is high relatively.Rotary type control magnetic sheet in like manner can change over flatly moving type control magnetic sheet as required, is used for controlling magnetic field.
