1%；Vehicle power is the superposition by two sets of dynamical systems, the half that every group of matched controller, battery only have total output to require.
Therefore, bimodulus motor need to only match the lower controller of two power, battery can form a high-power dynamical system；Relatively
In the configuration mode of usual single big power controller and battery, the reliability of dynamical system is substantially increased, power is reduced
Development cost and use cost reduce the use condition of controller and battery, improve ease of use.
Detailed description of the invention
Fig. 1 is the principles of the present invention block diagram.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.These are only used for elaborating the utility model,
The range of utility model is not limited in any way.
As shown in Figure 1, it is a kind of it is electronic it is automobile-used it is double hold up dynamical system it is main it include brake apparatus issue brake signal 5,
6, two controllers of speed-regulating signal, the two groups of batteries, a bimodulus motor of speed regulation device sending, wherein use inside bimodulus motor
Two independent three-phase line winding groups and one group of hall signal line 10；Fig. 1 three-phase line winding group 1 and three-phase line winding group 2(Fig. 1) it is one group corresponding
Hall signal 10, the relatively independent motor module unit of two of formation, two motor module units are separately connected controller
And battery forms two sets of power control systems that are relatively independent and mutually communicating；Communication connection is simultaneously between two power control systems
It is connect with speed regulation device and brake apparatus, while receiving external identical speed-regulating signal 6 and brake signal 5.
Further, three-phase line winding group winding mode described in two groups is consistent, and two groups of three-phase line winding group revolving speeds are almost the same.
Three-phase line winding group is independent in bimodulus motor and uses same group of magnet steel and Hall, uses two groups of battery electricity when two groups of independent batteries
Flattening bench is independent mutually, can be realized between battery and certain pressure difference occurs and can also be used with normal reliable.When two groups of cell voltages not
When consistent, the revolving speed that winding generates in two groups of motors is inconsistent, there are when small rotational speed difference, due to using same motor magnetic
Field, Hall, motor-field is interior to ensure dynamic equilibrium, and the high machine winding of motor internal rotation increases output torque, reduction turn
Speed；The low reduction torque of revolving speed promotes rotary speed；It is finally reached the balance of revolving speed, realizes turn that two groups of windings generate in motor
Speed is consistent substantially.
Further, the controller is two independent controllers, is filled respectively with same brake apparatus, speed regulation
It sets, Hall connection, receives identical speed-regulating signal, brake signal and hall signal, two controllers are connected as with battery respectively
The power supply of motor module unit, two controllers are connected from different three-phase line winding groups respectively, are able to carry out between two controllers
Communication connection, it is ensured that the optimal distribution of power.
A kind of electronic automobile-used double dynamical systems of holding up are two sets of relatively independent two set power control systems, common driving motor
Two groups of windings are rotated.One group of system is, three-phase line winding group 1, hall signal 10 and controller 9, battery 8, speed-regulating signal 6,
Brake signal 5 connects, and when controller 9 receives speed-regulating signal, while being communicated with controller 3, the also normal situation of controller 3
Under, driving motor three-phase line winding group 1 carries out stable rotation according to hall signal feedback position and stops when receiving brake signal
Only motor driven；Another group of system are as follows: three-phase line winding group 2, hall signal 10 and controller 3, battery 4, speed-regulating signal 6, braking
Signal 5 connects, and when controller 3 receives speed-regulating signal, while being communicated with controller 9, and controller 2 is also in normal situation,

The only driving of machine winding.
Controller 3 and controller 9 receive identical speed-regulating signal 6, brake signal 5 and hall signal 10, when controller 3 or
When controller 9 and speed-regulating signal 6, brake signal 5 fall off, controller 3 is communicated with controller 9, stops motor operation.
The battery is that two groups of independent batteries include battery 4 and battery 8, respectively two relatively independent motor moulds
Module unit power supply, when there are the revolving speeds for when pressure difference, causing winding 1 or winding 2 to generate deviation occurs between two groups of batteries, voltage is high
Speed it is high, the low speed of voltage is low；But motor internal magnetic field reaches balance to guarantee motor, guarantees motor normal rotation,
The high battery of voltage will export more high-power quickening electric quantity consumption, and the low battery output lower-wattage of voltage delays electric quantity consumption, most
Two groups of modules are promoted to reach the power output to balance each other eventually.
It is connect simultaneously with controller 9 and controller 3 alternatively, battery 4 is merged into a battery pack with battery 8, is two phases
