Description

A kind of motor generator

Technical field

The utility model relates to generator, relates to a kind of motor generator specifically.

Background technology

Existing power field mainly contains: multiple generation modes such as firepower, waterpower, nuclear power, solar energy, wind energy, biomass energy, geothermal energy, oceanic energy, but above-mentioned generation mode exists all that investment is high, maintenance cost is high, operating cost is high and defectives such as highly energy-consuming, high pollution.

Chinese patent 200420048527.3 provides a kind of motor generator, this motor is directly to adopt coaxial connection between motor and the generator, in fact this connected mode may not drive power output and carry out continuous firing than self high-power generator, main cause is: motor and generator all can have the part electric energy to convert heat energy to be consumed in the course of the work, and generator at work the charged back of stator and rotor because the effect of electromagnetic field will produce the load force with the motor switched in opposite, the big more load force that produces of output of a generator is also just big more, so when adopting coaxial connected mode, motor be subjected to load force influence its rotating speed can be more and more lower, especially drive the generator work bigger than its power output, this load force is enough to make motor to quit work.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, a kind of motor that utilizes high-speed rotation is provided, reduce rotating speed by change-speed gearing, increase output mechanical energy, increase power output, drive power output realizes generating than self high-power low-speed generator motor generator, this technology is a generator that makes full use of the lever mechanics principle, have pollution-free, advantages such as low energy consumption, and cost of investment, maintenance cost and operating cost all are significantly less than firepower, waterpower, nuclear power, solar energy, wind energy, biomass energy, geothermal energy, generation modes such as oceanic energy.

The concrete technical scheme that the utility model adopted is:

A kind of motor generator, it is characterized in that this motor generator comprises by relay, high-speed motor, gearbox, generator and inverter is connected in series the loop checking installation that forms successively, and an out-put supply end to outside electrical appliance output voltage is arranged at the tie point place of above-mentioned inverter and relay;

The initial voltage of above-mentioned loop checking installation derives from the power supply external with relay.

In existing power industry, no matter utilize chemical energy to convert mechanical energy to or directly utilize mechanical energy to generate electricity, its common principle all is to need to produce the load force that enough power overcomes generator, and the increase of electric energy produces in generator fully, and the former only provides a power that overcomes the load capacity of generator.

The utility model utilizes the lever mechanics principle to realize generating, as shown in Figure 1, lever with a long 110cm, when fulcrum hits exactly the 55cm mark at lever, respectively put the object of a 10kg at the two ends of lever, lever is in poised state, its balanced relationship is 55cm*10kg=55cm*10kg, when fulcrum moves to the 100cm mark when (as shown in Figure 2) to the B direction, the object that a quality is 10kg is put at B point place, it is that the object of 1kg will balance that a quality then only need be put in the A place, and its balanced relationship is 100cm*1kg=10cm*10kg.The The above results explanation is under the effect of lever arm of force, and the mechanical energy that the 1kg object produces is identical with the mechanical energy that the 10kg object produces.As shown in Figure 3, balance pivot is at the 100cm place, when the object of A point place placement greater than 1kg, the B point is placed the object of 10kg, lever will tilt to the A point keep inactive state after finally dropping down onto desktop, and this inactive state can keep forever, can illustrate by above-mentioned: the length that increases lever, can reduce the same ratio active force, but can not reduce the merit that mechanical the subject of knowledge and the object of knowledge is done.

The operation principle of travelling gear and lever is identical, most important link is the utilization of change-speed gearing in the utility model, change-speed gearing is in the course of the work along with the reduction of rotating speed, the mechanical energy that motor is exported increases (frictional resistance can be considered 0 when working in change-speed gearing is immersed in lubricating oil) that will be directly proportional with the multiple that rotating speed reduces is the straight line rising that is directly proportional as the form mechanical energy of the A line among Fig. 4; And generator is in the type of identical power output, the magnetic field area of generator unit stator that rotating speed is low and rotor can increase, the load force that produces increases, but because the density decline load force of the magnetic line of force also can descend, under the state of identical power output, the low generator of rotating speed not can and the high generator of rotating speed between rotating speed and load force, produce direct ratio, at this time the increase of the load force of generator as shown in Figure 4 the such curve of B line rise, the speed that curve rises is far smaller than the speed that straight line rises.

Can reach a conclusion by above-mentioned analysis: high-speed motor reduces rotating speed under certain condition by change-speed gearing, can provide enough power to drive the low-speed generator of power output fully greater than self power, general miniature diesel and gasoline engine generator are when assembled configuration, and the power output of diesel oil and gasoline engine gets final product greater than 0.9 times of output of a generator.Make motor reduce the part rotating speed even this explanation produces active force after generator is subjected to load, generator is run well as long as design variable in advance.

In sum, motor generator of the present utility model can be to realize electricity generate function.

It is little that motor generator of the present utility model has a volume, technology is simple, cheap, advantages such as noise is low and easy to maintenance, application is very extensive, it not only can build the power plant in a large number, efficiently, but also can be used as the lasting power supply of multi-field power consumption machineries such as the various vehicles, household electrical appliance, engineering machinery.
