Description

Method for overcoming back electromotive force resistance of magnetic suspension generator
Technical Field
The invention relates to a method, in particular to a method for overcoming the back electromotive force resistance of a magnetic suspension generator, and belongs to the technical field of motor industry.
Background
The generator is the basis of the development of the power industry and even the social economy, and has various energy structure forms, such as a hydroelectric generator, a thermal power generator, a wind driven generator, a nuclear power generator, a magnetic suspension generator and the like. The power generation principle of the generator has two forms: firstly, the conductor cuts magnetic lines of force; and secondly, generating power by closed circuit magnetic flux change. In any form of power generation, the power is used for doing work under the gravity condition. The magnetic field of the permanent magnet for the magnetic suspension generator enables the rotor of the generator to suspend, the moving track control of the rotor is realized, and only the mechanical friction caused by gravity and weightlessness is solved, namely, only a part of friction resistance problem of reducing power acting is solved. That is to say, the magnetic levitation technology cannot solve the problem that the efficiency of the generator is still disturbed by the back electromotive force and the magnetic hysteresis in the magnetoelectric induction process. Overcoming the hysteresis and back electromotive force of the generator always accompanies the whole process of generating electricity. Therefore, the existing magnetic suspension generator only solves the problem of frictional resistance caused by gravity, and hysteresis and counter electromotive force still exist. According to the energy conservation principle, magnetoelectric induction generates induction current, the induction current enables an induction coil to generate a reverse magnetic field, the reverse magnetic field has certain action with a magnet, and force action necessarily exists between a rotor and a stator, so the problems of magnetic hysteresis and counter electromotive force are naturally possessed by a generator and are irrelevant to the control of the suspension motion trail of the magnet. Therefore, the magnetic suspension generator is still the generator per se, and the magnetic suspension is only one of the devices for reducing power to do work. Magnetic hysteresis and back electromotive force exist objectively under the control of a magnet suspension motion trajectory, and are main reasons for a magnetic suspension generator to cause power work to be larger than generated energy. That is, the magnetic hysteresis and back emf problems alone are inherent in the generator magnetoelectricity, which causes drag between the generator stator and rotor. Without solving the problem of acting force between the induction coil and the magnet, the practical significance of magnetic suspension for reducing power to act is not realized. That is, the use of a power that maintains the relative motion of the magnetic field and the conductor to do more work than to generate power remains a ubiquitous problem that has not been addressed by our production practice.
Disclosure of Invention
The invention aims to provide a method for overcoming the counter electromotive force resistance of a magnetic suspension generator, wherein the magnetic suspension generator uses magnets or electromagnets as rotors of the generator, the magnets have different magnetic poles, one rotor simultaneously induces the stator coils of two groups of generators, the distribution of the forces generated by the magnets and the coils is symmetrical to the rotors, so that the resultant force of the rotors in the magnetic suspension and magnetoelectric induction processes is zero, and the problem that the stator coils apply negative work to the acting force of the rotors is solved. That is to say, two groups of stator coils are used for simultaneously inducing with one rotor, so that the problem that the traditional single group of rotor coils are stressed to do negative work can be solved, and the stress of the rotor is zero and no work is done. That is to say, the magnetic poles on the upper and lower surfaces of the rotor induce two groups of coils at the same time, so that the rotor is stressed at the same time, the resultant force is zero, and the optimal scheme for solving the magnetic hysteresis and the reaction between the coils and the magnets is provided, that is, the two polarities of the induction magnets on the magnetic suspension rotor simultaneously act on the two groups of stator induction coils to solve the unbalance phenomena of the magnetic hysteresis and the back electromotive force.
The technical scheme adopted by the invention for solving the technical problems is as follows: a method for overcoming the counter electromotive force resistance of a magnetic suspension generator is a method for inducing an upper corresponding stator coil group and a lower corresponding stator coil group at the same time by the same magnet on a magnetic suspension rotor so that the resultant force of the counter electromotive force resistance borne by the magnetic suspension rotor is zero or approaches to zero, and the specific structure of the method is as follows: the magnetic suspension magnetic block permanent magnet synchronous motor consists of a motor, a connecting shaft, a connecting upright post, an upper stator plate component, an upper magnetic block fixing plate component, a magnetic suspension rotor component, a lower magnetic block fixing plate component and a lower stator plate component. The upper stator plate assembly, the upper magnetic block fixing plate assembly, the magnetic suspension rotor assembly, the lower magnetic block fixing plate assembly and the lower stator plate assembly are connected in sequence through the four connecting upright posts. And the motor is fixed on the upper stator plate assembly and is connected with a connecting shaft, and the connecting shaft is connected with the magnetic suspension rotor assembly through a central hole of a magnetic suspension rotor plate on the magnetic suspension rotor assembly. The upper stator plate component is composed of an upper stator plate, an upper stator core column and an upper stator coil, the upper stator core column is uniformly arranged and fixed on the circumference of the upper stator plate, and the upper stator coil is connected to the upper stator core column. The upper magnetic block fixing plate assembly is composed of an upper magnetic block fixing plate and upper fixing plate magnetic blocks, wherein the upper fixing plate magnetic blocks are uniformly arranged and fixed on the upper magnetic block fixing plate in a circumferential mode. The magnetic suspension rotor assembly is composed of a magnetic suspension rotor plate, magnetic suspension plate magnetic columns, an upper magnetic block of the suspension plate and a lower magnetic block of the suspension plate, the magnetic suspension plate magnetic columns are uniformly arranged and fixed on the inner circumference of the magnetic suspension rotor plate through the magnetic suspension rotor plate, the upper magnetic block of the suspension plate is uniformly arranged and fixed on the upper surface of the outer circumference of the magnetic suspension rotor plate, and the lower magnetic block of the suspension plate is uniformly arranged and fixed on the lower surface of the outer circumference of the magnetic suspension rotor plate. The lower magnetic block fixing plate component consists of a lower magnetic block fixing plate and lower fixing plate magnetic blocks, and the lower fixing plate magnetic blocks are uniformly arranged and fixed on the circumference of the lower magnetic block fixing plate. The lower stator plate component consists of a lower stator plate, a lower stator core column and a lower stator coil, wherein the lower stator core column is uniformly arranged and fixed on the circumference of the lower stator plate, and the lower stator coil is connected to the lower stator core column.
The invention has the beneficial effects that: the magnetic suspension generator uses a magnet or an electromagnet as a generator rotor, the magnet has two polarities, namely a same magnetic pole and a different magnetic pole, and the same magnet on the rotor simultaneously induces two corresponding stator coil groups, so that the resultant force of magnetic hysteresis and back electromotive force borne by the magnetic suspension rotor is zero or approaches to zero, namely, the resistance is minimized. That is to say, under the magnetic suspension, the rotor reduces the power work under the magnetic suspension again, and increases the number of magnetic field poles and the length of the conductor, thereby increasing the power generation amount. The power is reduced to do work and the generated energy is increased under the magnetic suspension, so that the energy conservation and emission reduction under the magnetic suspension are realized, and the economic value and the application prospect are unlimited. More importantly: according to the principle of energy conservation, a magnetic suspension rotor rotates and simultaneously induces an upper group of coils and a lower group of coils to do power, and the electric quantity is increased in proportion. The technical scheme solves the problem that magnetic hysteresis and back electromotive force do negative work under magnetic suspension, and has great significance.
