Abstract
This invention relates to a magnetic filed energy generator by use of magnetic field energy, which changed the general idea that the electromagnetism force in the motor can be only used as medium part in energy exchanging and the itself energy are not fully utilized and still needs the one-time energy conversion to overcome the left-hand rule anti-torque to output power. This invention provides a new structure by use of the natural characteristics of the magnetic field to weaken the left-hand rule impact and to induce the mechanic power input by use of magnetic field energy local part to save the cost and decrease pollution.
Description
The present invention relates to a kind of generator that utilizes the magnetic field energy output power
The whole world all relies on the utilization of natural resources, converts required various energy to wherein to convert the widest indispensable link of national economy that becomes of electric power purposes to, and it is wide that electric power in use can not pollute local atmosphere and environmental application.
Task of the present invention provides a kind ofly utilizes energy in the magnetic field to reduce natural resources and the environmental pollution that is consumed in the electromechanical energy exchange, provide a kind of design that is different from conventional generator not only can fully excavate in the generator energy-saving potential but also can be to the improvement reference to some extent of existing generator.
The object of the present invention is achieved like this designs on conventional generator structure and operation logic basis, forming its difference by parts such as stator and rotors is that the energy design increases rotor axial length to increase the magnetic pole area in the magnetic field in order to utilize, and after stator shaft orientation length designs constant asymmetric structure routinely and make rotor put into stator, its equal in length of stator core is stretched out in two terminations, causes magnetic pole and magnetic field to produce the needs of electric power.
The iron core structure salient pole non-salient pole that increases rotor is all near former design material forged steel, and the 5%-100% rotor winding that the relevant preferred value with magnetic field energy of increasing value is the stator core axial length still connects conventional coiling and comprised rotor (3) and increased rotor (5) with a cover winding.
The latter two magnetic lines of force that send of stator and rotor core length asymmetric structure trend all separately change can make stator magnet line of force cutting rotor current in rotor airgap that produce with the strength reduction opposite opposing torque of prime mover, thereby the part energy becomes the purpose that electric power reaches energy-conservation of consumption reduction and reduces pollution in the taking-up magnetic field, and its energy-saving effect generator efficiency in 45% growth rotor is tested improves 15%.
Below in conjunction with accompanying drawing invention is further described.
Accompanying drawing 1 is a magnetic field energy generator configurations schematic diagram of the present invention.
Accompanying drawing 2 is that the magnetic field energy generator amature magnetic line of force of the present invention moves towards figure.
Accompanying drawing 4 is that stator magnet line of force generation opposing torque moves towards figure after the magnetic field energy generator resistance of the present invention load.
Magnetic field energy generator amature and stator adopt axial length asymmetric structure rotor, put into stator (1) back and stretch out identical growth rotor (5) at stator two ends, be wound with a cover field winding (4) on the rotor and (Fig. 1) save excitatory power, armature spindle and prime mover connect back prime mover with the M torque drag rotor to rated speed connect exciting curent (Fig. 2) whole length rotor (3) and increase section (5) all send separately the magnetic line of force (6) and (7) at this moment the magnetic line of force of generation two routes are arranged, one the tunnel is included in the magnetic line of force (6) that stator core rotor (3) sends equally passes air-gap with conventional generator become the loop in stator (1), another road be stretch out stator two ends increase in the rotors (5) the magnetic line of force (7) just rotor (3) the medium dip piggybacking in being included in stator (1) in rotor (3), by air gap also one-tenth loop in stator (1).The cutting stator winding increased the process (Fig. 2) that the induced electromotive force that produces in the stator winding is finished magnetic field energy generator input magnetic field energy that improved because rotor core increases the magnetic line of force after two road magnetic lines of force entered stator simultaneously.
When magnetic field energy generator unit stator winding (2) and external circuit are connected the resistive load electromotive power output, just there is stator current Chan Sheng And to send the stator magnet line of force (8) place in the middle of two magnetic poles of rotor simultaneously in the winding (2) and passes in cutting rotor winding current (4) generation and prime mover rightabout opposing torque M ' (Fig. 3) to rotor through air gap.
Because the characteristic that the magnetic line of force is the extremely strong ray of a kind of penetration power has the shortest passage of the minimum magnetic circuit of autonomous selection magnetic resistance to pass through has the objective law in loop of one's own, asymmetric stator of design and rotor axial length structure in the magnetic field energy generator, utilize this objective law stator magnet line of force (8) that the rotor in stator comprises (3) current is cut just and produce opposing torque M ', and the rotor (5) outside stator (1) length two ends increases in the part current (4), the magnetic line of force (8) but can not gone after the far-away at the expense of the near-at-hand cutting (Fig. 4) and be caused and weaken the corresponding minimizing of input that the left hand rule active force makes the suffered opposing torque M ' of whole length rotor and mechanical output, has reached to take out the power conservation natural energy source reduce the purpose that the effect of polluting has realized that magnetic field energy is generated electricity from part magnetic field.
Magnetic field energy generator embodiment of the present invention is an experiment with 8 centimeters asymmetric length values of 11.6 centimeters stator length of its rotor length of two pole generators is that 45% rotor of stator shaft orientation is that 2.4 kilowatts of actual measurements of Lu's utmost point formula energy output generator efficiency improves 15%.
