Description
Technical field
The present invention relates to a kind of motor, particularly a kind of motor with double mechanical port.
Background technology
Double-mechanical-port motor is a kind of motor with two mechanical ports, and main application is that motor vehicle driven by mixed power drives.One of them mechanical port links to each other with engine, and another mechanical port links to each other with vehicle drive shaft.Because two mechanical ports of this motor are independently, the road surface load variations that therefore is equipped with the motor vehicle driven by mixed power of this motor is not directly delivered to engine.Can control engine and always work in its efficient district, effectively raise the efficient of whole dynamical system, reduce discharging simultaneously.Aspect two of energy-conservation and environmental protection, all has crucial meaning.
At patent of invention CN1929243, CN1738163 has related to this motor among CN1945939 and the CN1694339.Though these motors have different specific implementations, the basic composition structure is identical.All has non-rotary stator, the internal rotor of rotation and external rotor.On stator and internal rotor, armature winding is installed, permanent magnet is installed on external rotor.Internal rotor is powered by brush and slip ring.The employing of slip ring has brought many-sided problem.The first, brush belongs to the rapid wear consumable part, and through work after a while, brush can be needed to replenish new brush by heavy wear.The second, the brush slip rings volume ratio is bigger, is not suitable for the more restricted occasion in space.Three, between brush and collector ring, there is contact voltage drop, when the electric current that passes through is very big, can between brush slip rings, produces very big contact loss.These losses finally can become heat, not only increase the weight of motor integral heat sink burden, also may damage armature and collector ring.Four, can produce a large amount of carbon dusts in brush and the collector ring friction process, these carbon dusts need in time remove, and therefore adopt the motor of brush and collector ring to need reasonable ventilation condition.And this conflicts with requirement that double-mechanical-port motor need seal.Non-brushing promptly removes brush and becomes the task of top priority.
Patent of invention CN1694339 has proposed a kind of method of non-brushing---resolver.The solution of this method success a series of problems of bringing by the power supply of brush and slip ring, but brought new problem again.When the rotating speed of two rotors of double-mechanical-port motor was close, the alternative frequency that carries out electric current in the resolver of internal rotor power supply was very low, and this moment, the efficient of resolver can be very low.Under this operating mode, the power supply of internal rotor can not realize.
Provided a kind of New-type electric machine among the patent of invention US6977454, this motor also has the essential characteristic of double-mechanical-port motor, i.e. two independent rotor rotated.In this New-type electric machine, provided a kind of magnetic structure of uniqueness, make this motor just can not carry out the non-brushing power supply to internal rotor by resolver.Successful solution resolver low problem of power supplying efficiency when two rotor speeds are close.But this structure only is applicable to the special occasions of two-phase power supply, is difficult to expand to three-phase even heterogeneous.And in general AC driving occasion, three phase supply is the most general.This limitations restrict the application of this structure.
Patent of invention CN1929243, CN1738163, the double-mechanical-port motor that designs among CN1945939 and the CN1694339 also have an apparent in view problem, i.e. internal rotor heat dissipation problem.This is because in these patents, internal rotor is positioned at the penetralia of whole double-mechanical-port motor, and rotates.Cold mode is dispelled the heat in can only adopting, and has brought the movable sealing and the wear problem of cooling circuit exit pipe joint thus.Moreover, interior cold design has increased the cost of whole system greatly.
Summary of the invention
The objective of the invention is to overcome double-mechanical-port motor in the existing patent needs brush power supply, internal rotor to be difficult to dispel the heat and the number of phases can not be different from the problem of two-phase expansion, has proposed a kind of brand-new double-mechanical-port motor.
The double-mechanical-port motor that the present invention proposes is made up of first stator, second stator, the first rotor and second rotor, four parts, wherein on two stators armature winding is installed.Post magnet steel on the first rotor, second rotor is made up of a series of dentalations.The supply power mode of two armatures all can be the form of any phase.When being applied to vehicle traction, the first rotor links to each other with vehicle drive shaft; Second rotor links to each other with engine output shaft; Second stator and second rotor produce electromagnetic action, and engine power is delivered on the first rotor.And regardless of the rotation speed relation of two rotors, the power that can effectively finish engine is by the transmission of second rotor to the first rotor.First stator and the first rotor produce electromagnetic action, replenish the deficiency of engine power, the process auxiliary drive vehicle.In a word, this New-type electric machine is finished identical with existing double-mechanical-port motor on function.
Two stators and two rotors of the double-mechanical-port motor that patent of the present invention proposes all are tray type structure, and two stators are in the outside, and two rotors are two stator inboards.
Second stator of the double-mechanical-port motor that patent of the present invention proposes has following feature, and its integral body is structure in the form of a ring, is made of several identical facies units, and these facies units are positioned at same plane.If when motor passes through three phase supply, be made of identical three parts, each part all accounts for the spaces of 120 degree.Each part promptly is a facies unit, and each facies unit constitutes by unshakable in one's determination and winding.Each cross section unshakable in one's determination is " recessed " font.Wherein the opening direction of " recessed " font is axial, and therefore three circular second stators that constitute unshakable in one's determination have formed two different annular end face of radius in the both sides of its opening.Winding is embedded in " recessed " font opening, and after feeding electric current, the iron core of each facies unit all forms a pair of magnetic pole in the radial direction at two different annular end face places of above-mentioned radius.Whole ring-type second stator forms three pairs of magnetic poles on end face.If be extended to m phase (m 〉=2, m is an integer), then need the stator of ring-type is divided into identical m part, each equal portions accounts for 360/m degree space, and whole ring-type second stator forms m to magnetic pole on end face.
The first rotor of the double-mechanical-port motor that patent of the present invention proposes has following feature, and its integral body is circulus, and magnet steel is installed on it, forms the magnetic pole of circumferencial direction alternate on two end faces of this rotor.The concrete layout of magnet steel is very flexible, can be Surface Mount, also can be Embedded.
Second rotor of the double-mechanical-port motor that patent of the present invention proposes has following feature, its integral body is dentalation, construction unit of adjacent a pair of dentation formation unshakable in one's determination, whole dentation second rotor by a series of such construction units in a circumferential direction cycle arrangement constitute, the number of dentation iron core is relevant with the number of pole-pairs of the first rotor.A construction unit that is made of the dentation iron core forms a pair of magnetic pole after feeding the magnetic line of force, this construction unit has four vertical end faces: two end faces and with second stator relative two end faces relative with the first rotor.Two end faces relative with the first rotor are that circumferencial direction is arranged, and form the south poles of circumferencial direction; Two end faces relative with second stator are radially arranged, and certain angle that staggers, and form south poles in the radial direction.Modulate by second rotor in the magnetic field that electric current produces in above-mentioned second stator.Second stator faces m in the radial direction is modulated into the magnetic pole of circumferential alternate to magnetic pole.Number of magnet poles is identical with the number of magnet poles of the first rotor.
Because the armature winding of two stators of double-mechanical-port motor of the present invention does not all need rotation, thereby avoided the problem that adopts brush and slip ring to power.The supply power mode of two armatures can be the form of any phase all, and having overcome can not be to the deficiency of two-phase other numbers of phases expansions in addition among the patent of invention US6977454.There is not the difference of heat radiation aspect in the position equalization of four parts of the present invention in whole system, so solved patent of invention CN1929243, CN1738163, the problem that internal rotor is difficult to cool off among CN1945939 and the CN1694339.

Embodiment
A kind of specific implementation of double-mechanical-port motor of the present invention as shown in Figure 1, this is a kind of disc type electric machine with axial magnetic flux, mainly being made up of four members with tray type structure, is first stator 1, the first rotor 2, second stator 23 and second rotor 3 successively.After the assembling moulding, two stators 1,23 are positioned at the outside, and two rotors 2,3 are positioned at the inboard of two stators 1,23, as shown in Figure 7.Wherein, second rotor 3 links to each other with engine output shaft 25, and the first rotor 2 links to each other with vehicle drive shaft 26.Without any mechanical connection, rely on the electromagnetic field in the interstice 18 on electromagnetism, to be coupled fully between two rotors 2,3.
Suppose that the engine output speed is n1, torque is T1, the output shaft rotating speed is n2, torque is T2, the power frequency that can control in second stator 23 is (n2-n1)/p, and p is a number of pole-pairs, the torque of opposing engine, because the effect of reaction force is delivered to motor torque T1 on the first rotor 2 by the electromagnetic coupled in the interstice 18.The power frequency of controlling simultaneously in first stator 1 is n2/p, and the output torque is T2-T1, replenishes the deficiency of engine power, makes that the total torque on the first rotor 2 is T1+ (T2-T1)=T2.
From the above-mentioned course of work as can be seen, T2 and T1, independent fully between n2 and the n1, therefore this double-mechanical-port motor has been realized the function of buncher.When T2*n2＞T1*n1, the intake of double-mechanical-port motor replenishes the underpower of engine less than the output energy.When T2*n2＜T1*n1, the output energy of double-mechanical-port motor reclaims the output energy of engine less than intake.
Different with existing double-mechanical-port motor is, in the double-mechanical-port motor that the present invention proposes without any slip feed part---promptly cancelled brush and slip ring.Identical functions is finished by second stator 23 and second rotor 3.Second stator 23 sees it is a loop configuration that has groove 7 on the whole, can be any number of phases, and the situation of three-phase as shown in Figure 2, at this moment, second stator 23 is made up of identical three parts, and each part is called a facies unit, and each facies unit is an arcuate structure.Each facies unit is corresponding to the phase in the motor power supply, and this facies unit structurally is made of unshakable in one's determination and winding.All fluted 7 in each facies unit, place winding 15 in the groove 7.After feeding electric current in the winding 15, will in facies unit, form magnetic pole 4 and 5, the flow direction of electric current has determined that magnetic pole 4 is the South Pole or the arctic, the polarity of magnetic pole 5 is in like manner.In order to form three symmetrical general layouts, each arc facies unit right central angle must be identical.Differ 120 electrical degrees between the original position of adjacent arc facies unit, if m then differs the 360/m electrical degree mutually.Differ an identical angle between the original position of previous facies unit end position and next facies unit, form breach 6.This breach 6 is that the end that holds winding 15 is used.In order to reduce the loss of torque, the angle between previous facies unit end position and the next facies unit original position should just can be held the end.
The first rotor 2 is p-m rotors, and the magnet steel of An Zhiing has produced the south poles distribution that circumferencial direction distributes on two end faces of this rotor thereon.The concrete form of its magnet steel is more flexible, can be surface-mount type magnet steel structure, also can be magneticfocusing magnet steel structure.Figure 4 shows that a kind of magneticfocusing magnet steel structure.Constitute by a series of magnet steel 11 and interpolar iron core 12.Magnet steel 11 is cutting orientation magnetizings, produces a magnetic pole in the interpolar iron core 12 of the magnetic line of force in the middle of these two blocks of magnet steel that per two adjacent magnet steel produce.The magnetic line of force that this magnetic pole produces is average flows to interstice 18 and the 3rd air gap 19, and polarity is identical.Polarity of the magnetic field in adjacent two interpolar iron cores 12 is opposite.The first rotor 2 also is a loop configuration, and two end faces are arranged, respectively in the face of the 3rd air gap 19 and interstice 18.Because the effect of magnet steel 11 has formed identical Distribution of Magnetic Field on these two end faces.With the magnetic field of first stator, 1 generation and the magnetic field of second rotor, 3 formation electromagnetic action takes place respectively.
The form of first stator 1 is more flexible, can be the specific implementation structure that has the disc type electric machine stator arbitrarily now.Shown in Figure 5 is a kind of fairly simple implementation, i.e. monolateral stator core, have the stator structure of concentrated winding.
