Description
Affiliated technical field
The utility model relates to a kind of motor, relates in particular to a kind of two circle structure direct current machine.
Background technology
The power that existing stepping motor produces torque is the stator field tangential force that magnetization attracts each other and forms to rotor magnetic pole, and the size of this tangential force depends on the magnetic field intensity of magnetic pole of the stator and the axial length of stator and rotor magnetic pole; For same motor, in the unsaturated scope of magnetic pole of the stator magnetic field intensity, the size of tangential force only depends on the magnetic field intensity (magnetic flux density) of magnetic pole.Promptly by the decision of magnetic potential number of ampere turns, this number of ampere turns can be multiturn number, little electric current to the size of this magnetic field intensity, also can be few number of turn, big electric current by what of the size of exciting current and the excitation winding number of turn; Obtain same magnetic potential, increase winding the number of turn, just can reduce exciting current, thereby improve efficiency of motor.The excitation module that comprises annular stator support and and excitation winding formation unshakable in one's determination by " Contraband " shape as Chinese patent 200520024685.X disclosed " wholecircle annular direct current machine " stator is existing and can not rotate continuously too, and its machinery inertial is suppressed can not bring into play its high efficiency defective.
Summary of the invention
The utility model provides a kind of two circle direct current machines of raising the efficiency at above deficiency.
In order to achieve the above object, the utility model adopts following technical proposal to realize:
The magnetic pole logarithm is more than 3 pairs,
Shape electromagnet, the two poles of the earth branch collapse at two circumference, are distributed on the cylinder stent inwall and constitute stator; The same stator of magnetic pole logarithm,
The ferrimagnet iron core that shape soft iron core or remanent magnetism are still less, magnetic conductance is bigger, the two poles of the earth branch collapses at two circumference, is distributed on arbor overcoat cylindrical and constitutes rotor, and rotor and stator have been formed two round structure homopolarities jointly with the circle DC motor.
Two circle structure homopolarities that rotor and stator constitute are with in the circle DC generator, rotor by
The shape electromagnet constitutes, stator number: rotor bank=3～8: 2～6.
Circular arc equates that with the magnetic pole external arc of rotor polar arc is less than 360 ° of merchants divided by the magnetic pole of the stator logarithm in the magnetic pole of the stator.
Cylinder stent, arbor overcoat are made by nonferromugnetic material.
Each armature outwards exports the intermittent continuous current electricity separately by diode rectification or continuous direct current is outwards exported in back in parallel.
Rotor of the present utility model moves required power and comes from the attraction that stator field magnetized rotor iron core produces each other under stator pole faces, for same motor, the size of this power is only determined by the magnetic field intensity of stator; The magnetic pole of the stator magnetic field intensity is big more, and the attraction between rotor magnetic pole is big more, otherwise then little; This power is not the electromagnetic force that produces from electrical conductor, and rotor does not need consumption of electric power yet, the moment of resistance that does not have the conductor cut magnetic line of force just not have the back electromotive force and the cut magnetic line of force to form; And this magnetic field intensity not only increases with the increase of winding exciting current, also increase simultaneously with the increase of umber of turn, when the intensity in required magnetic field was constant, umber of turn was many more, to consume exciting current few more, increase umber of turn and can reduce the electric current input, thereby raise the efficiency.In addition, this machine is fixed, and mobile between rotor magnetic pole is angular displacement, rotor R size no matter, and mobile angle equates that all when stator field intensity was constant, the increase rotor R also can increase motor torque, equally also can improve electric efficiency.
Illustrate: the power supply of rotary iron core formula five phase intermittent continuous current motor and p-m rotor five intermittent continuous current generator coaxle installation mutually, composition generator, motor unit, generator five phase power supplys insert 5 corresponding joint single-phase DC motor respectively; Under motor stator, rotor magnetic pole axial length, rotor radius, the situation of magnetic pole unit cross-sectional area umber of turn more than or equal to generator stator and rotor magnetic pole axial length, rotor radius, magnetic pole unit cross-sectional area umber of turn; Unit is borrowed the external force starting, makes rotor obtain an initial velocity, remove external force after, motor will continue to rotate.This is that generator has entered operating state when obtaining initial velocity owing to rotor, and 5 armatures begin to produce successively induced current, and every phase current enters corresponding 6 stator winding of single-phase DC motor and sets up magnetic field, the magnetized rotor magnetic pole, and the generation torque attracts each other; This size of current no matter, every moment of resistance (direction of motor, both attractions of generator is opposite) that the single-phase DC motor only need produce with 1 pair of armature magnetic pole of torque balance generator that 1 pair of magnetic pole produces, the torque pulling rotor that produces with 5 pairs of magnetic poles is rotated further, the phenomenon of output occur, but still follow law of conservation of energy greater than input.
Attract each other between motor stator and rotor magnetic pole, the process of pulling rotor rotation is exactly the process that the magnetic poles field energy converts mechanical kinetic energy to.The magnetic field intensity of magnetic pole characterizes the magnetic field energy of this magnetic pole, and the magnetic pole and magnetic field energy increases with magnetic field intensity; The power that attracts each other between motor stator and rotor magnetic pole increases with magnetic field intensity, increase with the magnetic pole and magnetic field energy increases exactly, just the mechanical function that is come by magnetic field energy conversion increases with the increase of magnetic field energy, and magnetic field energy converts the mechanical energy conservation to.The mechanical kinetic energy of magnetic field energy conversion is big more, and the attraction between motor stator and rotor magnetic pole is also big more; And the magnetic field intensity of magnetic pole is when exciting current is constant, also can increase its magnetic field intensity by the number of turn that increases excitation winding, (saying exactly, is to have increased the length that centers on the electrical conductor of iron core promptly to increase the magnetic field energy of magnetic pole, iron core has been concentrated the more magnetic line of force), magnetic field energy in other words.In the above-mentioned unit, motor increases the logarithm of magnetic pole of the stator by the number of turn that increases excitation winding, with big equally by the generator unit stator armature, little electric current, make 6 pairs of magnetic pole of the stator set up magnetic field with generator armature magnetic pole same intensity, 6 pairs fixed, rotor magnetic pole attracts each other simultaneously, 6 times of the attractions that produces are fixed to 1 pair in generator, the reverse attraction that rotor magnetic pole attracts each other and produces, the moment of resistance that the torque that motor produces produces greater than generator, realized output greater than input, made rotor speed progressively rise to the maximum of motor stator magnetic pole and magnetic field when saturated.
