Description
Technical Field
The invention relates to an energy and power system, in particular to an induction type magnetic energy generator with double magnetic rings.
Technical Field
In 1821, Faraday discovered that the electrified lead can rotate around the permanent magnet, and the permanent magnet motor is invented. In 1857, Wheatstone in UK replaced permanent magnet with electromagnet, invented the electric excitation mode, and created a new era of electric excitation motor. However, the above motors are only energy conversion tools.
The prior art is as follows: the patent refers to the field of 'dynamo-electric machines'. The constant magnetic fields of the rotor magnetic ring and the stator magnetic ring are converted into alternating magnetic fields by a mechanical method, the rotor magnetic ring and the stator magnetic ring are mutually attracted and repelled, and the magnetic bridge winding induces electromotive force according to the electromagnetic induction principle of a transformer to convert magnetic energy into electric energy. However, the manufacturing difficulty of the magnetic ring based on the Halbach array adopted by the induction type magnetic energy generator is higher.
The mixed excitation type magnetic ring consisting of the permanent magnet and the electromagnet is applied to the induction type magnetic energy generator, so that the production cost is favorably reduced.
Disclosure of Invention
The invention is realized by the following steps: the utility model provides a two magnetic ring induction type magnetic generator based on mixed excitation formula magnetic ring, mainly includes input shaft (1), rotor yoke (2), rotor magnetic ring (3), rotor magnetic ring (4), magnetic bridge (5), induction winding (6), casing (7) and prime mover, characterized by:
a. the rotor magnetic ring is a magnetic ring with three or more pairs of poles, wherein the three or more pairs of poles are formed by S magnetic poles and N magnetic poles which are formed by electromagnets and permanent magnets and are arranged alternately, and the number of the magnetic poles of the magnetic ring is a common multiple of 3; the stator magnetic ring is a mixed excitation type magnetic ring or a permanent magnet magnetic ring or an electromagnetic ring with six pairs of poles or more than six pairs of poles, wherein the S magnetic poles and the N magnetic poles are arranged alternately, and the number of the magnetic poles of the magnetic ring is a common multiple of 6; the number of the magnetic poles of the stator magnetic ring is 2 times of that of the rotor magnetic ring;
or the stator magnetic ring is a mixed excitation type magnetic ring with six pairs of poles or more than six pairs of poles, wherein the six pairs of poles are formed by electromagnets and permanent magnets, and the number of the magnetic poles of the magnetic ring is a common multiple of 6; the rotor magnetic ring is a mixed excitation type magnetic ring or a permanent magnet magnetic ring or an electromagnetic ring with three or more pairs of poles, wherein S magnetic poles and N magnetic poles are arranged alternately, and the number of the magnetic poles of the magnetic ring is a common multiple of 3; the number of the magnetic poles of the stator magnetic ring is 2 times of that of the rotor magnetic ring;
b. the magnetic bridge is used as a magnetic circuit of the stator magnetic ring and/or the rotor magnetic ring, and the magnetic bridge is provided with an induction winding;
c. the rotor is driven by the prime motor, when the rotor rotates, the rotating magnetic ring is an alternating magnetic field relative to the stator magnetic ring, the S pole and the N pole of the rotor magnetic ring alternately generate attraction and repulsion to the S pole and the N pole of the stator magnetic ring, the magnetic flux of the stator magnetic ring and the rotor magnetic ring is alternately changed, the constant magnetic field of the stator magnetic ring and the rotor magnetic ring is changed into a pulsating magnetic field, the magnetic flux passing through the magnetic bridge is alternately changed, and the induction winding induces electromotive force and generates current.
Because the number of the magnetic poles of the stator magnetic ring is 2 times or 1/2 times of the number of the magnetic poles of the rotor magnetic ring and is a common multiple of 3, no matter which angle the rotor magnetic ring arranged between the S pole and the N pole rotates, the suction force and the repulsion force of the rotor magnetic ring from the stator magnetic ring arranged between the S pole and the N pole are mutually offset, and the resultant force of the suction force and the repulsion force of the rotor magnetic ring is zero theoretically. So that only frictional forces need to be overcome for rotation of the rotor. In practice, it is difficult to make the magnetic fluxes of the magnetic poles of the rotor magnetic ring and the stator magnetic ring completely consistent, so that the rotor still suffers from a small amount of attractive force and repulsive force from the rotor magnetic ring and the stator magnetic ring, which cannot be offset.
The magnetic ring with 3 pairs of poles is equivalent to that the magnetic ring has 3S poles which are outward, 3N poles which are outward, 3S poles which are inward and 3N poles which are inward, and the magnetic ring with 6 pairs of poles is equivalent to that the magnetic ring has 6S poles which are outward, 6N poles which are outward, 6S poles which are inward and 6N poles which are inward.
The magnetic pole directions of the stator magnetic ring and the rotor magnet are radial or tangential or axial.
The mixed excitation type magnetic ring with 3 pairs of poles or more than 3 pairs of poles is composed of 3 or more than 3 electromagnets and 3 or more than 3 permanent magnets, and the permanent magnets and the electromagnets are arranged alternately. The 6 pairs of poles or more than 6 pairs of poles electromagnetic iron magnetic ring is composed of 6 or more than 6 electromagnets and 6 or more than 6 permanent magnets, and the permanent magnets and the electromagnets are arranged at intervals. The electromagnet consists of an iron core and an excitation winding, wherein the iron core is generally formed by laminating silicon steel sheets. The excitation windings of the electromagnets in the magnetic ring can be connected in series or in parallel.
The mixed excitation type magnetic ring is composed of radial and/or tangential and/or axial electromagnets and radial and/or tangential and/or oblique and/or axial permanent magnets, and the permanent magnets and the electromagnets in the magnetic ring are arranged at intervals.
The mixed excitation type magnetic ring is divided into two categories of a magnetic ring with a mixed excitation type common array structure and a magnetic ring with a mixed excitation type Halbach array structure.
The combination mode of the permanent magnet and the electromagnet in the mixed excitation type common array magnetic ring is as follows: radial permanent magnet + radial electromagnet or axial permanent magnet + axial electromagnet.
The permanent magnet and the electromagnet mainly comprise the following 5 combinations in a mixed excitation type Halbach array magnetic ring:
(1) radial permanent magnet and tangential electromagnet
(2) Tangential permanent magnet and radial electromagnet
(3) Radial electromagnet, tangential permanent magnet, tangential electromagnet and tangential permanent magnet
(4) Radial electromagnet, oblique permanent magnet, tangential electromagnet and oblique permanent magnet
(5) Radial electromagnet, oblique permanent magnet, tangential electromagnet, radial permanent magnet, tangential electromagnet and oblique permanent magnet
Since Halbach array magnets with axial pole directions are less useful, various combinations of magnets with axial magnets are not illustrated here.
The magnetic bridge is made of magnetic conductive material, generally made of silicon steel sheets by laminating, and the induction winding is a winding type winding. The case is made of a non-magnetic conductive material or a magnetic conductive material, and when the case is a part of the magnetic circuit, the case is made of a ferromagnetic material.
The prime mover is typically an electric motor with a battery. After the machine is started, part of the electric energy generated by the magnetic energy generator can be supplied to the motor in turn to maintain the continuous running of the machine. The electrical energy required for the operation of the motor may also be provided by an external power source. The power supply required by the electromagnet to generate the magnetic field can be provided by a storage battery or an external power supply.
Like a common generator, the output of electric excitation and electric energy needs a junction box. Like a common generator, an electromagnet and an induction winding of the magnetic energy generator can generate heat energy in the working process, and the generator needs to be additionally provided with a fan or a liquid cooling device. Like a common generator, the electric excitation of the magnetic energy generator needs to be rectified by a rectifier diode or a unidirectional silicon controlled rectifier, and the alternating current is converted into direct current to be output and also needs to be rectified by the rectifier diode or the unidirectional silicon controlled rectifier.
Like a common generator, a magnetic energy generator is divided into a direct current type and an alternating current type, and is divided into a single-phase generator and a three-phase generator according to the number of phases.
