Advantageous effect：
The utility model main innovation point is as follows：
1. one of the utility model innovation：Rotor simplifies when transmission flywheel, system.
The transmission shaft that heat power machine, generator, motor and mechanical rotation load directly is connected in the utility model, when
When individually using the load of fuel driven mechanical rotation, heat power machine must first drive generator and motor, then machinery is driven to turn
Dynamic load, though motor does not generate power at this time, generator does not also generate electricity, and rotor passively dallies, in heat power machine and machine
It is served as with buffering, the inertial flywheel stablized between tool rotation load.
It, will be electric when being rotated and being loaded by engine-driven relative to the system that other use engine and motor parallel
Machine detaches, although the friction of motor idle running, complicated, poor practicability can be reduced.And use the layout knot of mechanical series

Convenient for heat power machine Independent Power Generation, keep whole device simple and reliable for structure, while can facilitate and graft existing and very ripe combustion
Expect generator techniques, makes the utility model that there is good practicability.
The two of the utility model innovation：Generator, motor are transformed into anti-gravity bearing, system high efficiency.
When motor only makees transmission shaft and inertial flywheel, since rotor weight is heavier, certain friction energy loss is will produce, and

Frictional resistance.By increasing extraction wire in generator or motor stator, one group is isolated in stator winding top
Or multigroup winding, it is individually powered as anti-gravity Exciting Windings for Transverse Differential Protection, and to it, using stator core and rotor core, forms one
The electromagnet structure that can up attract rotor enables electromagnetic attraction size to allow generator or motor by controlling electric current
The horizontally-supported bearing of transmission shaft or together with vertical suffered by the horizontally-supported bearing of engine and mechanical rotation load transmission axis
Downward pressure reduces or is zero.Since the load of engine, generator, motor and mechanical rotation is horizontal installation, Er Qie
The weight of moving component in four, generator and motor rotor and transmission shaft is more with respect to what other component to be weighed, transmission shaft
When rotation bearing generate frictional force only it is related with the radial pressure straight down that bearing is born, and with mechanical rotation load
It is unrelated with the level of torque of transmission shaft, once the pressure reduces even zero, frictional resistance when bearing rotates will be substantially reduced,
Vibrations and noise can be reduced simultaneously.
This plain bearing adds the frame mode of rotor and anti-gravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
So that the gravity that bearing radial direction is born is reduced even to zero, is equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.Due to loading direct cascaded structure using engine, generator, motor and mechanical rotation, entire power generation at this time
Machine and motor are not only at the transmission shaft and flywheel of connection engine and mechanical rotation load, when coupling device is connected using rigidity
When connecing, also become the anti-gravity bearing that engine and mechanical rotation can be supported to load itself transmission shaft, thus is generated this instead
The entirety of gravitational effects is named as anti-gravity bearing.
Generator or motor become bearing, and anti-gravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but does not need to sending out in fact
Additionally increasing component on motor and motor body again, bearing, rotor and stator are all that generator and motor itself are existing,
Simply by optimization stator winding, increase extraction wire, produce unique anti-gravity Exciting Windings for Transverse Differential Protection structure, make have generator and
Motor becomes a huge anti-gravity bearing and a more good zero-g inertial flywheel, and cost only has magnetcisuspension
The some thousandths of that floating axle is held, this is exactly the ingenious place of the utility model.
When generator or motor need to restore power generation and driving function, pass through the switching list in anti-gravity control module
Member switches over the lead of anti-gravity Exciting Windings for Transverse Differential Protection, and anti-gravity Exciting Windings for Transverse Differential Protection is recovered immediately generator or motor
In stator winding.
Further, the utility model also has a variety of operating conditions, and therefore, flexibility is extremely strong, and operation is flexible, energy profit
With rate height, it is suitble to promote and apply.
