Modulated brushless double rotor motor 2 is briefly described, magnetic field modulation type brushless double-rotor machine 2 include stator 2-1,
Modulation rotor 2-2 and p-m rotor 2-3；Three-phase or polyphase windings is placed on stator 2-1；P-m rotor 2-3 and tradition
P-m rotor is identical, can use surface-mount type, the various ways such as built-in.The particularity of this electric machine structure is the tune of centre
Rotor 2-2 processed, it is to be made up of magnetic inductive block and non-magnetic block gap, by modulating the magnetic field modulation effect of rotor, makes
Obtain ectonexine air-gap field generation significant change, so that motor achieves energy converting between mechanical.
Magnetic field modulation type brushless double-rotor machine 2 has the advantage that than traditional double rotor electric machine
(1) need on a rotor of traditional double rotor electric machine to place winding, it is therefore desirable to electric brush slip ring structure is on rotor
Winding feeds.Electric brush slip ring structure can cause motor operational efficiency to decline, reliability reduces and needs are often safeguarded,
Make traditional double rotor electric machine cannot be applied in the middle of vehicle just because of this fatal structural disadvantages.By contrast, magnetic field is adjusted
The winding of type brushless double-rotor machine 2 processed is placed only in stator side, it is not necessary to electric brush slip ring structure feeds, therefore this electricity
Machine is without the problem of above-mentioned traditional double rotor electric machine.
(2) heating in winding on traditional double rotor electric machine rotor seriously and is difficult to cooling, by contrast, magnetic field modulation
Without winding on type brushless double-rotor machine 2 rotor, the most there is not the problem that rotor heating is serious.
(3) in traditional double rotor electric machine, rotor with winding is easy to be broken due to winding overhang dynamic balancing in rotary course
Bad, therefore after work certain time, traditional double rotor electric machine there will be the problems such as vibration noise.By contrast, magnetic field modulation
Type brushless double-rotor machine 2 is not because havinging this problem without winding on its rotor.
The operating characteristic that magnetic field modulation type brushless double-rotor machine 2 is met, and before explanation, have hypothesis below:
1. stator armature magnetic field number of pole-pairs, modulation rotor magnetic inductive block unit number and permanent magnetic field number of pole-pairs are p, q and n respectively.
2. stator armature rotational speed of magnetic field, modulation rotor rotating speed and p-m rotor rotating speed are Ω respectively2、Ω3And Ω1。
3. the electromagnetic torque acting on stator, modulation rotor and p-m rotor is T respectively2、T3And T1。
Then in magnetic field modulation type brushless double-rotor machine 2, between magnetic field number of pole-pairs, rotating speed and each parts, the relation of torque meets such as ShiShimonoseki
System:
Q=p+n (1)
From above-mentioned motor operating characteristic, this motor has a following features:
1. in magnetic field modulation type brushless double-rotor machine 2 stator armature magnetic field number of pole-pairs to can be differently configured from permanent magnetic field the most right
Number, as long as sum of the two is equal to magnetic inductive block unit number in modulation rotor.
2. stator armature rotational speed of magnetic field is by modulating rotor rotating speed and p-m rotor rotating speed together decides on, and fixed by changing
Sub-armature field rotating speed, can regulate modulation rotor and the speed discrepancy of p-m rotor, thus realize the only of two rotor speeds
Vertical operation.
3. p-m rotor 2-3, modulation rotor 2-2 and stator 2-1 three between electromagnetic torque there is certain ratio,
Changing one torque of any of which, other torque all can change accordingly.
According to embodiment, it is known that engine 1 is connected with p-m rotor 2-3.Assume that the torque that engine 1 exports is TICE,
Under stable situation, active force moment balance with the moment of reaction, it is known that
TICE=-T1 (5)
Can be obtained by formula (1), (3), (4) and (5)
In formula (3) to (8), negative sign represents in opposite direction.Due to q=p+n, so q/n ＞ 1.From formula (6) to (8),
The electromagnetic torque of modulation rotor 2-2 output is more than engine 1 input torque, and the electromagnetic torque etc. of modulation rotor 2-2 output
In engine 1 input torque and stator 2-1 electromagnetic torque sum, therefore, in terms of system input, this system is referred to as input
Synthesis type hybrid power system.When the timing of engine 1 input torque one, the electromagnetic torque of modulation rotor 2-2 output is delivered to
The torque of next stage is more than engine 1 input torque, and this is beneficial to the nominal torque value of torque adjustment motor 4 in reduction system.
From electric machine theory, the little volume and weight being conducive to reducing motor of Rated motor torque, the beneficially torque density of motor
And power density.For this, torque density limited to installing space and the higher vehicle of power density requirements, input is made to synthesize
Type hybrid power system has bigger using value.
Below the mode of operation of input synthesis type hybrid power system is illustrated.In this system, different working modes is to pass through
In maintaining body 3, the switching of first clutch 3-1, brake 3-2 and second clutch 3-3 realizes.In order to make each work
The form of expression of pattern becomes apparent from, and only depicts the connection of main element in each mode of operation schematic diagram, and automobile control
Portion processed is not the most given.In each mode of operation schematic diagram, first clutch 3-1 or second clutch 3-3 combination will with line segment
It is connected with clutch connected components；First clutch 3-1 or second clutch 3-3 separates then and nothing between clutch connected components
Line segment connects；Brake 3-2 combination Shadow marks represents, is fixed with Shadow marks connected components；Brake 3-2 separates then
Shadow marks is removed, and is in free state with brake 3-2 connected components.
Pattern I: first clutch 3-1 separates, brake 3-2 combines, second clutch 3-3 combines, as shown in Figure 4.
Now the modulation rotor 2-2 in magnetic field modulation type brushless double-rotor machine 2 and the rotor in torque adjustment motor 4 are all consolidated
Fixed, i.e. vehicle is in dead ship condition.Modulation rotor 2-2 is fixed, i.e. Ω3=0, then magnetic field modulation type brushless double-rotor
Motor 2 can regard the single-rotor motor of traditional structure as, and the torque rotary speed relation in motor can be determined to (8) by formula (1).
Under this pattern, when battery 6 electricity deficiency, engine 1 it is driven, magnetic field modulation type brushless double-rotor machine 2
As generator operation, by double-rotor machine control circuit 14, battery 6 is charged.If engine 1 needs to open
Time dynamic, then battery 6 provides electric energy by double-rotor machine control circuit 14 for magnetic field modulation type brushless double-rotor machine 2,
Magnetic field modulation type brushless double-rotor machine 2, as motor running, drives engine 1 to light a fire after reaching certain speed again
Start.This can reduce oil consumption in engine 1 start-up course, especially can be substantially reduced under needs frequent starting operating mode
Start oil consumption.
Pattern II: first clutch 3-1 separates, brake 3-2 combines, second clutch 3-3 separates, as shown in Figure 5.
Now vehicle is individually driven by torque adjustment motor 4, it is possible to achieve the acceleration of vehicle, cruise, slow down, car-backing function.
And in the case of the modulation rotor 2-2 in magnetic field modulation type brushless double-rotor machine 2 is fixed, this hybrid power system
System can realize series model and run.So-called series model refers to that mechanical energy is first changed into electric energy by motor by engine 1, electricity
The mechanical energy required for wheel-borne load 17 can be changed into again by another motor.Within the system, due to modulation rotor
2-2 is fixed, then magnetic field modulation type brushless double-rotor machine 2 can regard the single-rotor motor of traditional structure as.Now, send out
Motivation 1 converts mechanical energy into electric energy by magnetic field modulation type brushless double-rotor machine 2, then controls electricity by double-rotor machine
Road 14 is by electrical power storage in battery 6, and battery 6 be that torque adjustment is electric by torque adjustment circuit for controlling motor 15
Machine 4 provides electric energy, and now torque adjustment motor 4 is as motor running, is driven wheel-borne load 17；Or send out
Motivation 1 converts mechanical energy into electric energy, by double-rotor machine control circuit by magnetic field modulation type brushless double-rotor machine 2
Electric energy is directly inputed to torque adjustment motor 4, torque adjustment motor 4 conduct through torque adjustment circuit for controlling motor 15 by 14
Motor running, is driven wheel-borne load 17.When wheel-borne load 17 needs braking, torque adjustment motor 4 conduct
Generator operation, the mechanical energy of wheel-borne load 17 is converted into electric energy through torque adjustment motor 4, by torque adjustment motor
Control circuit 15 by electrical power storage in battery 6.Because engine 1 driving magnetic field modulated brushless double rotor motor 2
Carry out generator operation and torque adjustment motor 4 drives or only exists electrical connection between brake wheel load 17, therefore two
Can independently carry out between link.Therefore series model ensure that engine 1 accomplishes that peak efficiency is run all the time, and torque
The duty of regulation motor 4 is determined by wheel-borne load 17 demand.Because fuel efficiency is very under lower-speed state for engine 1
Low, therefore this pattern can improve car load fuel economy under low cruise.
Pattern III: first clutch 3-1 separates, brake 3-2 separates, second clutch 3-3 combines, as shown in Figure 6.Now
This system can realize paralleling model or series-parallel connection mode operation, it is possible to achieve the acceleration of vehicle, cruise, slow down, car-backing function.
So-called paralleling model refers to that mechanical energy is directly passed to wheel-borne load 17 by engine 1, and torque adjustment motor 4 is by battery 6 simultaneously
Electric energy is converted into mechanical energy and is also passed to wheel-borne load 17 or some mechanical can be converted into electric energy stores in battery 6.At figure
In 6, when in magnetic field modulation type brushless double-rotor machine 2, stator 2-1 rotational speed of magnetic field is zero, from electric machine theory, stator electricity
Port side does not has electric energy to change, i.e. engine 1 output all passes out from modulation rotor 2-2 to the mechanical energy of p-m rotor 2-3
Go.At Ω2When=0, the torque rotary speed relation between modulation rotor 2-2 and engine 1 can determine to (8) according to formula (1).
Battery 6 electric energy is converted into mechanical energy and is also passed to vehicle load 17 by torque adjustment motor 4 simultaneously, or by machine unnecessary for part
Tool can be converted into electric energy and store in battery 6.Therefore pattern III can realize paralleling model operation.
So-called series-parallel connection pattern refers to that system has the feature of series model and paralleling model concurrently.In figure 6, brushless when magnetic field modulation type
When in double-rotor machine 2, stator field rotating speed is not zero, then show to have carried out turning of electric energy and mechanical energy in stator 2-1 port side
Change.
A kind of situation is: a part for engine 1 output to p-m rotor 2-3 mechanical energy creates electric energy at stator 2-1 port,
By double-rotor machine control circuit 14, electric energy is stored in battery 6 again, and battery 6 is controlled by torque adjustment motor
Circuit 15 provides electric energy for torque adjustment motor 4, and now torque adjustment motor 4 is as motor running, enters wheel-borne load 17
Row cutting；Or engine 1 output creates electric energy to a mechanical energy part of p-m rotor 2-3 at stator 2-1 port, passes through
Electric energy is directly inputed to torque adjustment motor 4, torque through torque adjustment circuit for controlling motor 15 by double-rotor machine control circuit 14
Wheel-borne load 17, as motor running, is driven by regulation motor 4.And another part mechanical energy of engine 1 is by adjusting
The rotor of rotor 2-2 processed and torque adjustment motor 4 is directly passed to wheel-borne load 17, and is driven wheel-borne load 17.
Therefore, from the path of energy transmission, a part of mechanical energy of engine 1 passes through magnetic field modulation type brushless double-rotor machine 2
Creating electric energy, this part electric energy is converted to mechanical energy through torque adjustment motor 4 again and finally exports wheel-borne load 17；Send out
Another part mechanical energy of motivation 1 is directly output to wheel-borne load 17.
Another kind of situation is: a part for modulation rotor 2-2 output mechanical energy is converted into electric energy through torque adjustment motor 4, this
Time torque adjustment motor 4 as generator operation, this part electric energy is stored in battery by torque adjustment circuit for controlling motor 15
In 6, and battery 6 provides electric energy for magnetic field modulation type brushless double-rotor machine 2, now by double-rotor machine control circuit 14
Magnetic field modulation type brushless double-rotor machine 2, as motor running, converts electric energy to mechanical energy from modulation rotor 2-2 output；
Or a mechanical energy part for modulation rotor 2-2 output is converted into electric energy through torque adjustment motor 4, by torque adjustment motor
Electric energy is directly inputed to magnetic field modulation type brushless double-rotor machine 2 through double-rotor machine control circuit 14, now by control circuit 15
Magnetic field modulation type brushless double-rotor machine 2, as motor running, converts electric energy to mechanical energy from modulation rotor 2-2 output.
And the another part modulating rotor 2-2 output mechanical energy is directly passed to wheel-borne load 17 by the rotor of torque adjustment motor 4
And wheel-borne load 17 is driven.On the one hand the total mechanical energy of modulation rotor 2-2 output turns from brushless pair of magnetic field modulation type
Sub-motor 2 is as the mechanical energy of conversion during motor running, on the other hand from the mechanical energy of engine 1 input.Therefore, from
Seeing on the path of energy transmission, the mechanical energy of engine 1 output is transported as motor with magnetic field modulation type brushless double-rotor machine 2
During row, the mechanical energy of conversion together passes from modulation rotor 2-2, and modulates a total mechanical energy part for rotor 2-2 output
Being converted into electric energy through torque adjustment motor 4 and feed back to again magnetic field modulation type brushless double-rotor machine 2, another part is directly output to
Wheel-borne load 17.
In both cases, the change of the duty of magnetic field modulation type brushless double-rotor machine 2 and torque adjustment motor 4
Change, actually ensure that the duty of engine 1 can be independent of wheel-borne load 17.
Therefore under pattern III, on the one hand by magnetic field modulation type brushless double-rotor machine 2 and torque adjustment motor 4 to rotating speed and
The regulation effect of torque makes the rotating speed of engine 1 and torque independent of the rotating speed of wheel-borne load 17 and torque, makes engine 1 all the time
It is operated on optimal fuel oil curve, thus reduces the purpose of oil consumption and exhaust emissions；On the other hand by paralleling model
Or series-parallel connection mode operation interval is optimized, the fuel economy of car load can be greatly enhanced.
Pattern IV: first clutch 3-1 separates, brake 3-2 separates, second clutch 3-3 separates, as shown in Figure 7.Now
Vehicle is individually driven by torque adjustment motor 4, it is possible to achieve the acceleration of vehicle, cruise, slow down, car-backing function.Electric power storage
Pond 6 provides electric energy by torque adjustment circuit for controlling motor 15 for torque adjustment motor 4, and now torque adjustment motor 4 is as electronic
Machine runs, and is driven wheel-borne load 17；When wheel-borne load 17 needs braking, torque adjustment motor 4 is transported as generator
OK, the mechanical energy of wheel-borne load 17 is converted into electric energy through torque adjustment motor 4, by torque adjustment circuit for controlling motor 15
By electrical power storage in battery 6.And for magnetic field modulation type brushless double-rotor machine 2, due to its modulation rotor 2-2
Being in free state, the while of reaching poised state without impressed torque, its rotating speed is the most uncertain, from formula (1) to (8),
Magnetic field modulation type brushless double-rotor machine 2 cannot be carried out energy conversion.But pattern IV can be used as a kind of transition mode, for pattern
Switching between II and pattern III.Because the transition mode time is comparatively short under normal circumstances, and first clutch in maintaining body
3-1 separates, brake 3-2 separates or there is certain resistance in the cohesive process of second clutch 3-3, and therefore this pattern can
Out of control with avoid engine to cause because instantaneous velocity change is too high.
Pattern V: first clutch 3-1 combines, brake 3-2 combines, second clutch 3-3 combines, as shown in Figure 8.Now
The rotor of engine 1, p-m rotor 2-3, modulation rotor 2-2 and torque adjustment motor 4 is all fixed, i.e. vehicle is in parking
