Abstract
A cylindrical rotor alternator pertains to the art of generator technology in order to solve the problem that the rotor must revolve when the generator is working. The technical proposal is that an internal cylindrical shell made of high-permeability material and an external cylindrical shell integrated outside with the internal cylindrical shell to support the rotation are arranged in the gap location between the generator stator and the generator rotor. The internal and external cylindrical shells are respectively provided with a special symmetrical magnetic leakage hole and the position of the magnetic leakage hole on the external cylindrical shell is arranged just opposite to the magnetic field direction of the stator. As the rotor does not rotate when the generator is working, the magnetic line goes through the magnetic leakage hole on the internal and external cylindrical shells and then though the rotator when the magnetic leakage hole on the internal cylindrical shell turns to the magnetic field direction. Instead, the magnetic line avoids the rotor through a closed magnetic shield constituted by the internal and the external cylindrical shells and the magnetic flux changes to produce induced electromotive force. The main purpose of the utility model is to improve the rotor of the generator for saving energy and providing a novel generator.
Description
Technical field
The utility model belongs to technical field of generators, relates to a kind of alternator of cylindrical rotor.
Background technology
In the experiment of AC and DC generator principle, the parts of the generator principle demonstrating model of use mainly contain rotor, stator, commutator (Dyn.), two slip rings (alternator), brush, lead and sensitive reometer or miniature bulb etc.When with the rotor rotation of hand moving generator, rotor is done the cutting magnetic induction line motion in magnetic field, and then variation has taken place the magnetic flux of rotor winding.Therefore, in the rotor of generator demonstrating model, just produce induction electromotive force, in the closed circuit of forming by sensitive reometer or miniature bulb, just had induction current to produce.
Summary of the invention
The purpose of this utility model provides a kind of alternator of cylindrical rotor, and when this generator work, its rotor does not rotate and has only the inner cylinder housing made from high permeability material to rotate.This inner cylinder housing rotation produces induction electromotive force, improves the rotor of generator owing to can make electric generator rotor coil magnetic flux change with this.
The technical solution of the utility model is: use high permeability material and make a magnetic shield that is made of inner cylinder housing and out cylinder housing, and this magnetic shield is made up of two parts, first is called the inner cylinder housing, it is bottom surface sealing on its of drum, and offers the leakage field hole of special-purpose symmetry on its drum body.Second portion is called fixed out cylinder housing, also offers in the above and the corresponding symmetrical leakage field of inner cylinder housing hole, and the position in the leakage field hole that this is symmetrical is installed in the magnetic direction that faces generator unit stator.The inner cylinder housing is the inside that is installed in fixed out cylinder housing, and it can constitute a kind of magnetic shield of sealing around fixing out cylinder housing rotation under the driving of input shaft.When generator is worked, when the leakage field hole of the symmetry on the inner cylinder housing turns to facing to the stator field direction, then magnetic induction line with regard to passed through should symmetry the leakage field hole pass rotor.When the leakage field hole of symmetry on the inner cylinder housing turns to when carrying the stator field direction, because magnetic induction line has passed through the sealing magnetic shield that is made of inner cylinder housing and out cylinder housing, the characteristic that has low magnetic resistance according to high permeability material, the magnetic shield of sealing can play a part along separate routes magnetic flux, make the overwhelming majority of the magnetic line of force all avoid rotor by magnetic shield, then rotor winding magnetic flux changes and produces induction electromotive force.
Effect of the present utility model and benefit are the rotors that has improved generator, and found in the physics " electromagnetic induction " " about producing the argumentation of induction current condition: no matter promptly how; change as long as pass the magnetic flux of closed circuit, induction current is just arranged in the closed circuit with this." no matter the utility model is exactly this one of how example.
Description of drawings
Accompanying drawing 1 is a kind of inner cylinder shell structure synoptic diagram of alternator of cylindrical rotor.
Accompanying drawing 2 is alternator construction synoptic diagram of a kind of cylindrical rotor.
Among the figure: 1 inner cylinder housing, 2 symmetrical leakage field holes, 3 input shafts, 4 out cylinder housings,
5 symmetrical leakage field holes, 6 stators, 7 rotors, 8 sensitive reometers.
Embodiment
Be described in detail specific embodiments of the invention below in conjunction with technical scheme and accompanying drawing.
On the air gap position of the rotor 7 of generator and stator 6, an inner cylinder housing 1 and a fixed out cylinder housing 4 that supports this inner cylinder housing 1 rotation usefulness that utilizes high permeability material to make has been installed.Inner cylinder housing 1 is to utilize the permalloy material of one of high permeability material to make, and it is bottom surface sealing on its of a drum, and has input shaft 3 at the one end.What particularly point out is the leakage field hole 2 that offers the symmetry of a pair of special use on inner cylinder housing 1, and inner cylinder housing 1 is sleeved on the inside of the out cylinder housing 4 that supports its rotation usefulness, and can rotate under the driving of input shaft 3.Fixing out cylinder housing 4 also is to make with the permalloy material, also offers the leakage field hole 5 with inner cylinder housing 1 corresponding a pair of special-purpose symmetry on fixing out cylinder housing 4.The position in the leakage field hole 5 that this is symmetrical faces the magnetic direction of generator unit stator 6 when mounted, makes the magnetic induction line of stator 6 directly to pass rotor 7 by the leakage field hole 5 of symmetry on the fixing out cylinder housing 4.And rotor 7 does not rotate when generator is worked, and the coil plane of rotor 7 is vertical with the magnetic direction of stator 6.
When generator is worked, when making 1 rotation of inner cylinder housing by input shaft 3, when the leakage field hole 2 of its symmetry turns to facing to the magnetic direction of stator 6, promptly when the leakage field hole 5 of symmetry on the fixing outer cylindrical shell 4 overlaps, then the magnetic induction line in magnetic field has just passed through symmetrical leakage field hole 2 and 5 and passed rotor 7.When the leakage field hole 2 of the symmetry on the inner cylinder housing 1 turns to the magnetic direction of carrying stator 6, promptly with fixing out cylinder housing 4 on the leakage field hole 5 of symmetry when being positioned at the position of staggering, then magnetic induction line has just passed through the body of the magnetic shield of a sealing being made up of inner cylinder housing 1 and fixing out cylinder housing 4, makes rotor 7 avoid magnetic induction line.Therefore, in rotor 7 with regard to variation that magnetic flux is arranged and produce induction electromotive force, by a closed circuit of forming by lead and sensitive reometer 8,, demonstrated the function of the alternator generation of this cylindrical rotor with the pointer of sensitive reometer 8 phenomenon that swings.
