The one,, inside rotor is buckled in stator, sealing generator in the enclosure, without any heat abstractor, when generator operation, cannot dispel the heat in inside, make stator winding in the time that bringing onto load moves, because internal resistance exists cannot leaving in time taking heating as the reactive power of presentation of producing, long-time running, can damage the coil of generator, thereby affect the useful life of generator;
The 2nd,, due to without heat abstractor, generator must adopt the installation form exposing, by the opening of coil windings outwardly, so that heat radiation, thereby, in the time that motor High Rotation Speed moves, very dangerous, have very large potential safety hazard;
The 3rd,, motor magnetic tile is pasted with AB glue and rotor, and the invalid temperature of glue is at 105-130 DEG C, once motor temperature is too high, motor magnetic tile can come off, and causes motor to work;
The 4th,, the magnetic shoe in generator amature, adopts Ferrite Material to be made, and so the volume of magnetic shoe is large, efficiency is low, and output voltage waveforms distortion rate is high, and loading range is undesirable, and machine volume is large.
Summary of the invention
Technical barrier to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of compact conformation, volume is little, security performance is good electric generating formula distance increasing unit generating set are provided.
Technical solution of the present utility model is, is made up of gasoline engine and generator 5, and gasoline engine comprises engine 1, engine air filter 2, fuel tank 3 and muffler 4, and generator 5 comprises power spindle 19, rotor 8 and stator 9; The rotor 8 of generator 5 is fixed on power spindle 19, and rotates with power spindle 19; Stator 9 is fixed on generator case 17 and base by support 10, it is characterized in that: the radial section of rotor 8 is U-shaped, and its U-shaped rotor 8 arranges outwardly back to end cover of engine 6, opening; The U-shaped back of the body end outside of rotor 8 is provided with fan 7, and fan 7 is placed between end cover of engine 6 and rotor 8, and rotates with rotor 8; Generator case 17 is located at the outside of rotor 8, and generator case 17 and the as a whole foundry goods of end cover of engine 6.
The power spindle 14 of described generator 5 is the crank connecting link output shaft of engine 1.
The inner circumferential of rotor 8 is evenly provided with the magnetic shoe 16 of being made up of high-performance rare-earth material.
The support 10 of generator 5 is a castings, and centre is fixed in the above stator 9 by screw 14; Periphery is a circular shell, is connected with generator case 17 by screw 15, and afterbody is fixed with hood 11 by screw 12, makes generator 5 form the outer cover that has complete closure.
Between fan 7 and rotor 8, fix by screw 18, or as a whole foundry goods between fan 7 and rotor 8.
The advantage that the utility model compared with prior art possessed is,
(1) outside of generator amature design has increased fan, and fan is directly fixed on the rotor of motor, when engine rotor rotation, fan will increase exhaust air rate to greatest extent, whole generator frame is carried out to air draft cooling, good cooling results, has improved bulk life time;
(2) pressing of change generator stator and rotor fills direction, makes the opening of rotor outwardly, heat radiation in the body of being more convenient for, and compact conformation, reasonable, and radiating effect is better;
(3) be located at the magnetic shoe of rotor inner side, adopt high-performance rare-earth material to make, volume simple in structure is little; Due to the Hyperploidy of material property, make motor volume of the present utility model dwindle 1/3rd compared with prior art, ensure the feasibility of totally-enclosed distance increasing unit electric machine structure.
(4) compact integral structure, volume is little, and hermetically sealed housing cover cap is safe and reliable, good looking appearance.
