For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: the starting circuit of motor; Comprise: start button, power switch, starting relay, total magnetic switch, starting motor, storage battery, generator, protective relay, motor magnetic switch and latching relay; The positive pole of storage battery links to each other with positive source through the normally opened contact group of total magnetic switch; The positive pole of storage battery links to each other with the control end of total magnetic switch and the normally opened contact of latching relay through power switch; The positive pole of storage battery also links to each other with the positive pole of starting motor through the normally opened contact group of motor magnetic switch; The normally-closed contact of latching relay links to each other with the control end of the control end of protective relay, motor magnetic switch; The control end of latching relay links to each other with the neutral line of generator, and the contact of stirring of an end of start button, the forward output terminal of generator, latching relay links to each other with positive source, and the other end of start button links to each other with the control end of starting relay through the normally opened contact group of protective relay; Positive source also links to each other with the startup trigger end of starting motor through the normally opened contact group of starting relay, and protective relay, starting relay, starting motor, motor magnetic switch, storage battery, total magnetic switch, generator, latching relay grounding end separately all link to each other with power cathode.
The corresponding contacts of the normally opened contact group of said total magnetic switch links to each other with positive source through being prone to fuse; The forward output terminal of said generator links to each other with positive source through being prone to fuse.
The forward output terminal of said generator links to each other with the positive pole of storage battery through the normally opened contact group of total magnetic switch.
Be serially connected with a pair of easy fuse between the normally opened contact group of the forward output terminal of said generator and total magnetic switch.
Described total magnetic switch and motor magnetic switch are the direct solenoid contactor.
The beneficial effect of the utility model is: the described starting circuit of the utility model; Increased protective relay, motor magnetic switch and latching relay, and, the neutral line of generator is linked to each other with the control end of latching relay; Behind engine start; The neutral line of generator goes out electricity, and the normally-closed contact of pushing latching relay open cuts off the main power circuit of motor magnetic switch, thereby has guaranteed that starting motor can not appear at the phenomenon of oppositely beating tooth behind the engine start.Because the main power circuit of motor magnetic switch has been cut off, return is bad even ignition switch starts shelves, also can not duplicate the startup phenomenon, thereby protect starting motor well.

Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 1; The starting circuit of the said motor of the utility model; Comprise: start button 1, power switch 2, starting relay 4, total magnetic switch 6, starting motor 8, storage battery 9, generator 10, protective relay 3, motor magnetic switch 5 and latching relay 7; The positive pole of storage battery 9 links to each other with the normally opened contact of the normally opened contact group of total magnetic switch 6, and the contact of stirring of this normally opened contact group links to each other with positive source through being prone to fuse 11; The positive pole of storage battery 9 links to each other with the control end of total magnetic switch 6 and the normally opened contact of latching relay 7 through power switch 2; The positive pole of storage battery 9 also links to each other with the positive pole of starting motor 8 through the normally opened contact group of motor magnetic switch 5; The normally-closed contact of latching relay 7 links to each other with the control end of protective relay 3, the control end of motor magnetic switch 5; The control end of latching relay 7 links to each other with the neutral line (the centre cap N end of generator armature) of generator 10; The contact of stirring of one end of start button 1, latching relay 7 links to each other with positive source; The forward output terminal B+ of generator 10 links to each other with positive source through being prone to fuse 12; The other end of start button 1 links to each other with the control end of starting relay 4 through the normally opened contact group of protective relay 3; Positive source also links to each other with the startup trigger end of starting motor 8 through the normally opened contact group of starting relay 4, and protective relay 3, starting relay 4, starting motor 8, motor magnetic switch 5, storage battery 9, total magnetic switch 6, generator 10, latching relay 7 grounding end separately all link to each other with power cathode, all pass through bonding usually and link to each other; In the present embodiment; Between the forward output terminal B+ of said generator 10 and the normally opened contact group of total magnetic switch 6 except the connecting line through positive source links to each other; Also be provided with special-purpose charging circuit; That is: the forward output terminal B+ of generator 10 links to each other with another root special wire with the contact of stirring of the normally opened contact group of total magnetic switch 6; And stirring of the normally opened contact group of an end of this special wire and total magnetic switch 6 is provided with easy fuse 13 between the contact, is serially connected with between the forward output terminal B+ of the other end of this special wire and generator 10 to be prone to fuse 14; Described total magnetic switch 6 is the direct solenoid contactor with motor magnetic switch 5.
