[detailed description of the invention]
Below in conjunction with accompanying drawing, with regard to presently preferred embodiments of the present invention, the invention will be further described:
As shown in Figure 1:
Basic composition is of electronic (generating) machine of 3 bodies: rotor (14), impact rotor (2) and stator (5) composition；Totally 3 core
Parts form；Referred to as 3 body motor (electromotor).
Basic functional principle: when stator coil (44) has electric current to pass through, will generate driving moment (rotor to rotor (14)
Can be permanent magnetism or sensing or magnetic hysteresis mode)；When rotor (14) is accelerated to certain speed, will be with impact rotor
(2) colliding, this collision is that the direct collision clashed between post (41), (42) by rotor is realized.
This collision can make non-contacting soft collision；As shown in the profile of the hatching MM of Fig. 1.Turning at 2 rotors
Son clashes into post (41), (42) can be provided with permanent magnet；When rotor clash between post (41) and (42) close to each other time, magnetic field
Repulsion, by increase drastically, is alleviated collision, and is made contactless collision set up.
During 2 rotors collisions occur, part is transferred to impact rotor by the energy of rotor (14) and momentum
(2)；At the end of collision each time, rotor (14) is all returned by impact rotor (2) bounce-back.
In whole collision process, the electromagnetic force of stator (5) can put on rotor (14) all the time, to increase the biography of energy
Defeated efficiency.
When rotor (14) is repelled, stator coil (44) continues to accelerate, and rotor clashes into post (41) and (42)
When not producing bounce-back relative displacement collision, rotor (14) is made to be accelerated to again exceed the speed of impact rotor (2)；And then complete
Collide next time；Go round and begin again, move in circles.
(13) be casing, (3) be power output shaft；(40) it is power input shaft.
Through-put power is estimated: set the quality of rotor as M, rotary inertia I；Collision relative rotation be 160 degree (rotor (14) with
The angle free to rotate of impact rotor (2))；Angular velocity before the collision of rotor (14) is W1, the angular velocity of impact rotor (2)
Approximation is at the uniform velocity W2；Collision between rotor (14) and impact rotor (2) is approximately elastic collision；Rotor (14) is when accelerated
Average angular acceleration be A.
Thus can approximate estimation:
The moment of momentum in unit interval and exchange of kinetic energy:
The exchange moment of momentum=[collision frequency of unit interval] x [moment of momentum crossing-over value of primary collision]
Thus: [collision frequency of unit interval]=(W1-W2)Weighted average/2Π
[crossing-over value of the moment of momentum of primary collision]=I (2W1-W2)
In formula: Π=pi
Exchange of kinetic energy=[collision frequency of unit interval] x [the exchange of kinetic energy value of primary collision]
[the exchange of kinetic energy value of primary collision]=1/2I [W1W1-(2W2-W1)2]
Through-put power is estimated: take the mass M=2KG of rotor
Rotary inertia (radius is 10 centimetres) I=2/102KGM2
Angular velocity before the collision of rotor (14) is W1=180 Π
The angular velocity approximation of impact rotor (2) is at the uniform velocity W2=60 Π
Approximation draws: moment of momentum exchange=360 (KGM/S)
Exchange of kinetic energy=17000 (W)
In the ordinary course of things: automobile-used 3 body motors be 2 the most used in parallel, to obtain good dynamic balancing；In this situation
Under, the pull strength of car is 100KG；Output is 34KW；Speed per hour is 110KM/S.
In the case of vehicle start: 3 body motors are provided that there is much bigger driving moment than conventional 2 body motors；This kind
In the case of, W2=0；Take W1For intermediate value (120 Π)；Pull strength is about 220KG；Acceleration for car that quality is 1200KG
For 0.18G；The acceleration time obtaining 0 110KM/H is only 6 seconds！
Even if in the case of stopping completely, also can obtain bigger moment for a long time, this has essence with 2 body motors
Difference, under larger current, any 2 body motors also cannot work long hours on the premise of obtaining larger torque；Because only blocking
Heat effect in the case of Si just be enough to cause catastrophic consequences.
The stator coil of 3 body motors in this case, constantly absorbs during collision and releases energy；Namely
Constantly recharge discharge process, meets the balance of energy；And between rotor and stator, it is in the work of higher relative velocity
Under the conditions of work；It is that under low speed, state is fabulous.
Patten transformation:
# conflicting model；Being particularly suited for middle low speed, super large moment exports.
#2 body motor/power generation mode；Impact process stops, and locked between 2 rotors (without relatively rotating), now returns
Return conventional 2 body motor mode.
