The utility model is described in further detail below in conjunction with most preferred embodiment and accompanying drawing: shown in accompanying

drawing

1,2,3,4,5,6, this multifunction electric generator comprises stator 10, rotor 11, collector ring 12, carbon brush 13, its characteristics are to have on the stator 10 main winding 21 and pay winding 22, its number of poles is four utmost points, and the main winding 21 of every utmost point and pay winding 22 and be contained in the core slots 24 of stator 10 by the concentric manner of coaxial homophase, and every main winding 21 under extremely all has corresponding binding post A1 and X1, A2 and X2, A3 and X3, A4 and X4; Winding 25 on the rotor 11 is four utmost point multilayer windings; On the stator 10 each under extremely pay winding 22 mutually serial connection after rectification circuit, carbon brush 13 and collector ring 12 again with rotor 11 on winding 25 be connected, wherein rectification circuit can be existing various rectification circuit, but the best is a single-phase full wave bridge rectifier and through regulating the rectification circuit of resistance R 2; As shown in Figure 3, for the ease of the conversion of the utility model between electricity generate function and electric welding function, in the outside of stator 10 switchboard 15 is housed, and the wiring change over switch B of main winding binding post is housed on switchboard 15, and wiring change over switch B the best can adopt the change over switch of HZ10-100/8 model; When wiring change over switch B the generating the position time, four main windings under extremely are connected in series mutually, best A1 and X1 string A2 and X2 string A3 and the 240 volts of required output voltages of electrical equipment such as X3 string A4 and X4 output illumination pressed are about to binding post X1 and A2, X2 and A3, X3 and A4 conducting respectively; When the position of wiring change over switch B in electric welding, four main windings under extremely mutually and connect, the best is pressed: it is an output that binding post X1, A2, X3, A4 are communicated with, and it is another output that binding post A1, X2, A3, X4 are communicated with, 60 volts of low-voltages and big electric current that its output electric welding is required; As shown in Figure 6, in order to make this multifunction electric generator a tractor serves several purposes, the output when electric welding contact again rectifier diode CZ5 and charging current adjuster C(the best can be regulate resistance R 1) back just can realize the function that charges the battery; Because output current is bigger during electric welding, wiring change over switch B is burnt out, therefore the wiring change-over panel P of the main winding binding post of Chinese People's Anti-Japanese Military and Political College's electric current also is housed on switchboard 15, be used to replace wiring change over switch B to realize the electric welding function conversion, therefore wiring change over switch B only adopts the change over switch of cheap HZ10-25/4 model just can meet the demands, wherein wiring change-over panel P is by wiring change-over panel P1 and another group main winding binding post A1, X2, A3, X4 and wiring change-over panel P2 and another group main winding binding post x1, A2, X3, two groups of formations of A4, when being used for electric welding, earlier change over switch B is placed on neutral position, again wiring change-over panel P1 is inserted into binding post A1, X2, A3, make its conducting on the X4, too wiring change-over panel P2 is inserted into binding post X1, A2, X3, make its conducting on the A4, and when being used to generate electricity, only need two set of connections change-over panel P are extracted out from its corresponding binding post, and then wiring change over switch B is placed on the generating position gets final product; Use for the ease of this multifunction electric generator, as shown in Figure 3, generating lead-out terminal M1 and N1 also are housed on switchboard 15, electric welding lead-out terminal M2 and N2, charging lead-out terminal M3 and N3, generating lead-out terminal M1 and N1 can be connected on respectively on the output that wiring change over switch B is wiring change over switch HZ10-100/8 or wiring change over switch HZ10-25/4, electric welding lead-out terminal M2 and N2 can be connected on respectively on the output or main winding binding post A1 and X1 of wiring change over switch HZ10-100/8, as shown in Figure 6, charging lead-out terminal M3 can be connected on the main winding binding post A1, and charging lead-out terminal N3 serial connection direct current Table A, regulate resistance R 1, be connected on again behind the rectifier diode CZ5 on the main winding binding post X1; For the ease of observing the situation of change of voltage, electric current, frequency, shown in accompanying drawing 3,7, alternating voltage Table V, alternating current Table A, frequency meter HZ are housed also on switchboard 15.The motive power of this multifunction electric generator can be provided by motive power machines such as diesel engine, gasoline engine, the hydraulic turbines respectively.
