Description
Technical field
The utility model relates to a kind of with the multipole permanent-magnet arc welding electric welding unit of internal combustion engine as power.
Background technology
What the arc generator of the internal combustion engine of Xiao Shouing (comprising gasoline engine, diesel engine)-electric generator structure 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 present oil-engine driven arc-welding electric welding machine exist copper, silicon steel consumption big, cost height, volume heaviness, defectives such as poor welding quality.
Along with the development of inverter circuit topology form and the maturation of semiconductor devices, inverter type welder has appearred.The circuit structure of inverter type welder generally is to adopt the rectification → inversion → process of rectification, i.e. interchange → direct current → interchange 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.
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, simple and reliable for structure, arc-welding electric welding unit that welding quality is high.
The technical solution of the utility model is achieved in that multipole permanent-magnet arc welding 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, generator unit stator is fixedly mounted on the IC engine airframe and is positioned at generator amature, the output of generator unit stator winding connects reactor, and at least two pairs of permanent magnets are installed in the generator amature.
Described generator unit stator winding is single-phase winding, and reactor is in the output that is connected on single-phase winding.The generator unit stator winding also can be the three-phase winding, and reactor is three, and each phase winding output connects a reactor.
The output termination rectifier of described reactor.Described rectifier is a controlled rectifier.
The utility model had both had the high advantage of inverter type welder welding quality, overcome the above-mentioned deficiency of oil-engine driven traditional arc-welding electric welding machine again, it is simple and reliable to have a circuit structure, materials economize, in light weight, volume is little, cost is low, the less demanding characteristics of manufacture level.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The multipole permanent-magnet arc welding electric welding of the utility model unit, comprise 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 IC engine airframe and is positioned at generator amature.Improvement of the present utility model is, is equipped with manyly to (at least two pairs) permanent magnet in the generator amature, and this moment, the ac frequency of generator unit stator output was the product of rotor speed and magnetic pole logarithm.As adopt 10 pairs of utmost point permanent magnets, when rotor rotates with 3600 rev/mins (speed is 60Hz), then Shu Chu ac frequency is 600Hz.Generator can be single-phase, also can be three-phase.Single-phase generator needs a reactor, and each of three-phase generation output needs a reactor mutually, so that generator has the voltage steep drop characteristic.Single-phase electricity just can be directly as AC arc welding behind reactor, also can be again after controlled or uncontrollable rectification as direct-current arc welding.Three-phase electricity is through reactor, again through controlled or uncontrollable rectification as direct-current arc welding.
Fig. 1 is first kind of embodiment structural representation of the utility model, and generator unit stator winding 1 output single-phase alternating current, reactor 2 are that output has the alternating current of voltage steep drop characteristic in the output that is connected on single-phase winding.
Fig. 2 is second kind of embodiment structural representation of the utility model, generator unit stator winding 1 output three-phase alternating current, and each phase winding output connects a reactor 2, carries out rectification by three-phase full-bridge rectifier 3 again, and output has the direct current of voltage steep drop characteristic.
Fig. 3 is the third embodiment structural representation of the utility model, generator unit stator winding 1 output three-phase alternating current, each phase winding output connects a reactor 2, carries out three-phase controlled rectification by three-phase controlled rectifier 3 again, and output has the direct current of voltage steep drop characteristic.Sensor 4 among the figure is used to detect parameters such as the DC voltage, electric current of output, 5 of controllers are controlled controlled rectifier 3 in conjunction with some parameter of setting simultaneously according to these parameters of sensor 4 feedbacks, make the DC voltage of output and electric current in the magnitude range of needs.
