As shown in Figure 1:
Basic composition is of electronic (generating) machine of 3 bodies: rotor (14), impact rotor (2) and stator (5) are formed; Totally 3 core components are formed; Be referred to as 3 body motor (generator).
Basic functional principle: when stator coil (44) has electric current to pass through, will generate driving moment (rotor can be permanent magnetism or induction or the magnetic hysteresis mode) to rotor (14); When rotor (14) when being accelerated to certain speed, will bump with impact rotor (2), this collision is to realize through the direct collision between rotor bump post (41), (42).
This collision can make non-contacting soft collision; Shown in section Figure 1A of the hatching AA of Fig. 1.Rotor bump post (41), (42) at 2 rotors can be equipped with permanent magnet; When between the rotor bump post (41) and (42) each other near the time, the repulsion in magnetic field is alleviated rapid increase to collide, and makes contactless collision establishment.
In the process that the collision of 2 rotors takes place, the energy of rotor (14) and momentum will partly be transferred to impact rotor (2); Rotor (14) was all returned by impact rotor (2) bounce-back when collision each time finished.
In whole collision process, the electromagnetic force of stator (5) can put on rotor (14) all the time, to increase the efficiency of transmission of energy.
When rotor (14) was rebounded, stator coil (44) made it continue to quicken, and rotor bump post (41) and (42) make rotor (14) be accelerated to the speed above impact rotor (2) again when not producing bounce-back relative displacement collision; And then accomplish next time and collide; Go round and begin again, move in circles.
(13) be that casing, (3) are power output shaft; (40) be power input shaft.
The through-put power estimation: the quality of establishing rotor is M, moment of inertia I; The collision relative rotation is 160 degree (angles free to rotate of rotor (14) and impact rotor (2)); To be that the angular speed of W1, impact rotor (2) is approximate at the uniform velocity be W2 to angular speed before the collision of rotor (14); Collision between rotor (14) and the impact rotor (2) is approximately elastic collision; The average angular acceleration of rotor (14) when being accelerated is A.
But thereby approximate estimation:
The moment of momentum and exchange of kinetic energy in unit interval:
The exchange moment of momentum=[collision frequency of unit interval] x [moment of momentum cross-over value of primary collision]
Thereby: [collision frequency of unit interval]=(W

In the formula: ∏=circumference ratio
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 [W

Angular speed before the collision of rotor (14) is W1=180 ∏
The angular speed of impact rotor (2) is approximate at the uniform velocity to be W2=60 ∏
Approximate drawing: moment of momentum exchange=360 (KGM/S)
Exchange of kinetic energy=17000 (W)
In the ordinary course of things: automobile-used 3 body motors are 2 parallel connection uses together, to obtain good dynamic balancing; In the case, the tractive effort of car is 100KG; Power output is 34KW; Speed per hour is 110KM/S.
Under the situation of vehicle start: 3 body motors can provide than conventional 2 body motors has much bigger driving moment; In such cases, W
2=0; Getting W is median (120 ∏); Tractive effort is about 220KG; The acceleration that for quality is the car of 1200KG is 0.18G; The accelerating time that obtains 0-110KM/H is merely 6 seconds!
Even under the situation of stopping fully, also can obtain bigger moment for a long time, this and 2 body motors are essentially different, and any 2 body motors also can't work long hours under the prerequisite that obtains big moment under big electric current; Because the thermal effect under the only stuck situation just is enough to cause catastrophic consequences.
The stator coil of 3 body motors is in such cases, in striking process, constantly absorbs and emits energy; Continuous recharge discharge process just satisfies the balance of energy; And be under the condition of work of higher relative velocity between rotor and the stator; Be that state is fabulous under the low speed.
Mode switch:
The # conflicting model; Be particularly useful for middle low speed, the output of super large moment.
#2 body motor/power generation mode; The impact process is ended, and between 2 rotors locked (nothing relatively rotates), returns conventional 2 body motor mode this moment.

# change group digital modeling: change on the same group the quantity of magnetic pole the group number is changed, then organize number and increase, then organize number when number of magnetic poles increase on the same group and reduce when number of magnetic poles on the same group reduces.
# equivalence rotating magnetic field pattern: this mode is to realize through exchange border magnetic pole between each group; Soon respectively organizing adjacent magnetic pole shifts; The border magnetic pole of this group is allocated to adjacent group; Absorb the magnetic pole of another adjacent magnetic pole set simultaneously, the quantity of every group of magnetic pole is remained unchanged, shift the exchange rotating magnetic field clockwise and turn clockwise; Shift the exchange rotating magnetic field counterclockwise and then be rotated counterclockwise (being equivalent to (56)) along its rotating shaft rotation.
# composite mode: the combination of above-mentioned each pattern (rotation of change group number/equivalence/to).
As shown in Figure 4:
