The wound type motor greatly reduces the failure rate of a slip ring of the motor after adopting an internal slip ring structure, guarantees connecting points on a rotor firm, and assures the favorable operation of the motor under any conditions. In addition, the structure can conveniently make the slip ring into a higher protection grade.
Description
Technical field
The utility model relates to motor, relates in particular to a kind of wound motor.
Background technology
Along with rapid economy development, customer requirement motor single-machine capacity is increasing, and therefore for wound motor, the voltage of its rotor, electric current are also increasing.The outer slip ring structure of the general employing of existing wound motor.There is following drawback in outer slip ring structural electromotor: the one, and the rotor voltage height can cause that the rotor lead wire punctures; The 2nd, when rotor current was very big, the sectional area that passes the connecting line of axis hole also needed very big, and the difficulty of the shaping of connecting line, heat radiation, connection will be increasing.
Fig. 1 shows a kind of coiling electric motor of existing outer slip ring structure.
As shown in Figure 1, the coiling electric motor of traditional outer slip ring structure comprises motor body 101, and the two ends of motor body 101 are provided with end cap 103, and slip ring chamber 104 independently is arranged on outside the end cap 103.Be provided with some slip ring conducting rings 105 in the slip ring chamber 104, slip ring conducting rod 106 is connected with slip ring conducting ring 105 by bolt.Rotor on the motor body 101 is drawn and is connected its junction bolted with slip ring conducting rod 106 after busbar 102 passes axis hole.
This structure is because motor body and slip ring chamber are separate, and rotor is drawn busbar and walked line length, and it is big to connect difficulty, and the junction bolt, and reliability is not high.Under high voltage, big current conditions, be easy to produce fault.Therefore, existing outer slip ring structure can not adapt to the needs of large wound motor, thereby needs a kind of new slip ring structure to satisfy user's requirement.
The content of utility model
The applicant at the large wound motor of outer slip ring structure in use because high voltage, big electric current often produce the problem of fault, has carried out research and has improved, and provides another kind of wound motor, slip ring structure in adopting.
The technical solution of the utility model is as follows:
A kind of wound motor, comprise motor body 201 and slip ring chamber 204, the two ends of motor body 201 are provided with end cap 205, motor body 201 is connected with a rotor and draws busbar 202,204 inside, slip ring chamber are provided with at least one slip ring conducting ring 206, be connected with slip ring conducting rod 207 on the slip ring conducting ring 206, rotor is drawn busbar 202 and is connected with slip ring conducting rod 207, device on motor body 201 has inner end cap 203 in end cap 205 inside, installs described slip ring conducting ring 206 between inner end cap 203 and end cap 205 in rotating shaft 208.
Further:
Described slip ring conducting rod 207 is drawn busbar 202 with rotor and is rectangular strip.
Described slip ring conducting rod 207 has at least one aperture with the junction that rotor is drawn busbar 202, and the wired clamping in junction is fixed.
Useful technique effect of the present utility model is:
After the slip ring structure, rotor was drawn busbar cabling weak point in coiling electric motor adopted, and it is low to connect difficulty, and the failure rate of motor sliding ring reduces greatly.Can guarantee that each tie point is firm on the rotor, can guarantee that motor can both finely move under various conditions.In addition, this structure is also convenient makes more senior degree of protection with slip ring.

Fig. 2 is a structure chart of the present utility model.
Fig. 3 is the busbar johning knot composition of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 2 is a structure chart of the present utility model.
As shown in Figure 2, a kind of wound motor, comprise motor body 201 and slip ring chamber 204, the two ends of motor body 201 are provided with end cap 205, motor body 201 is connected with a rotor and draws busbar 202,204 inside, slip ring chamber are provided with at least one slip ring conducting ring 206, be connected with slip ring conducting rod 207 on the slip ring conducting ring 206, rotor is drawn busbar 202 and is connected with slip ring conducting rod 207, device on motor body 201 has inner end cap 203 in end cap 205 inside, installs described slip ring conducting ring 206 between inner end cap 203 and end cap 205 in rotating shaft 208.Slip ring chamber 204 is distinct with the air path system of machine body 201 like this, can guarantee both sides heat radiation mutually noninterfere, can guarantee that also the carbon dust in the slip ring chamber 204 can not enter in the motor body 201.This structure has good reliability at large-size machine or high-speed electric expreess locomotive and design, and can guarantee that motor can both finely move under various conditions.
Fig. 3 is the busbar johning knot composition of Fig. 2.
As shown in Figure 3, slip ring conducting rod 207 is drawn busbar 202 with rotor, and the both is a rectangular strip, but width is different.Both junctions are bored and are joined several apertures, and by silver-bearing copper weldering welding, it is good to handle weld strength like this, even rotor high-speed also was difficult for unclamping when rotating.The junction is fixed with wire clamp, can not rock when guaranteeing the motor high speed rotating or loosening.Weld with silver-bearing copper too between slip ring conducting rod 207 and the slip ring conducting ring 206, each junction all is hard connection like this, is connected firmly.Above-mentioned syndeton is hard connection, and is solid, reliable, particularly big electric current or high-revolving motor, and such structure seems more reliable.
The above only is a preferred implementation of the present utility model, is appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
