What the internal combustion engine of Xiao Shouing (comprising gasoline engine, diesel engine)-electricity generation and electric welding unit adopted in the market is excitation generator.Big, the Heavy Weight of this excitation generator volume, copper, silicon steel use amount are big.Because generator is generally single to utmost point excitation, what send is the alternating current identical with speed, and such ac frequency is low, require reactor thereafter need have bigger inductance value, makes reactor produce high material consumption, heavy shortcoming equally.Just because of these reasons, make at present to exist copper, silicon steel consumption big cost height, volume heaviness, defectives such as poor welding quality with oil-engine driven electricity generation and electric welding unit.
Along with the development of inverter circuit topology form and the maturation of semiconductor device, inverter type welder has appearred.The circuit structure of inverter type welder generally is to adopt the process of rectification of rectification → inversion → again.Because the reverse frequency of inverter type welder is higher, transformer weight reduces, and the volume of welding machine is little, in light weight, and the quality of welding is improved.
Because there is the process of rectification of rectification → inversion → again in inverter type welder, the circuit link is more, and control is complicated, compares the metal rectifier welding set of present stage, and manufacture level requires to compare higher.
Ac frequency shakiness, wave distortion that while existing internal combustion engine-electricity generation and electric welding unit sends are big.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provide a kind of materials economize, in light weight, volume is little, generating and the high multipole permanent magnet reversible electricity generation and electric welding unit of welding quality.
The technical solution of the utility model is achieved in that multipole permanent magnet reversible electricity generation and electric welding unit, it comprises internal combustion engine, generator unit stator, generator amature and reactor, generator amature is fixedly mounted on the internal combustion engine output shaft, and generator unit stator is fixedly mounted on the internal combustion (IC) engine airframe and is positioned at generator amature; At least two pairs of permanent magnets are installed in the described generator amature; Be wound with the electric welding winding and the generating winding of mutual insulating on the generator unit stator, the output of electric welding winding connects reactor, and the output of generating winding connects current-variable controller.
Described electric welding winding is single-phase winding, and reactor is in the output that is connected on single-phase winding.The output termination rectifier of reactor, described rectifier is a controlled rectifier.
Described electric welding winding also can be the three-phase winding, and this moment, reactor was three, and each phase winding output connects a reactor.The output termination rectifier of reactor, described rectifier is a controlled rectifier.
