Abstract
The present utility model discloses a coiling motor lead wire structure which comprises a lead wire connected with a rotor winding. The lead wire is formed by laminating a plurality of thin copper sheets with same shapes, and the number of the thin copper sheets is arranged according to the rotor current. Compared with the prior lead wire structure which employs single copper bar, the new coiling motor rotor lead wire structure is not easily bended, the technology difficulty is small, the production beat is shortened, the skin effect of the rotator current is reduced, the copper use amount is small, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of coiling electric motor rotor, especially relates to a kind of coiling electric motor rotor lead wire structure.
Background technology
At present, the rotor current of a lot of winding rotor motors is very big, so rotor winding lead wire all adopts the copper bar structure, see also shown in Figure 1, Fig. 1 is the schematic diagram of traditional coiling electric motor rotor lead wire structure, traditional rotor winding 10 connects single copper bar 12 by joint 11 and carries out lead wire, and there is following deficiency in this structure:
1) single copper bar is harder, curves comparatively difficulty of suitable stationary shape, and technology difficulty is bigger;
2) copper consumption is big, production cost height, productive temp length consuming time.
The utility model content
The purpose of this utility model is to provide a kind of coiling electric motor rotor lead wire structure, and it has and is easy to curve solid shape, and technology difficulty is little, and cost is low, the characteristics that " kelvin effect " is low.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of coiling electric motor rotor lead wire structure, it comprises the lead wire that is connected with the rotor winding, wherein, described lead wire is stacked mutually by several scale copper to be formed.
Especially, described scale copper tool is identical shaped.
Especially, described lead wire is stacked mutually by 40 scale coppers to be formed, and the thickness of single scale copper is 0.5mm.
The beneficial effects of the utility model are, the lead wire of described coiling electric motor rotor lead wire structure is made up of the scale copper that several stack mutually, the quantity of described scale copper is according to the size setting of rotor current, lead wire structure than traditional single copper bar of employing not only is easy to bending, and technology difficulty is little, shortened productive temp, and " kelvin effect " of rotor current reduction, copper consumption is few, has reduced production cost.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the schematic diagram of traditional coiling electric motor rotor lead wire structure;
Fig. 2 is the schematic diagram of the utility model coiling electric motor rotor lead wire structure.
Embodiment
Please refer to shown in Figure 2ly, Fig. 2 is the schematic diagram of the utility model coiling electric motor rotor lead wire structure.In present embodiment, described coiling electric motor rotor lead wire structure comprises the lead wire 22 that is connected with rotor winding 20 by joint 21, described lead wire 22 is stacked mutually by several scale copper 23 to be formed, and described scale copper 23 tools are identical shaped, equally also can be different shapes.
According to rotor current, calculate the ampacity of copper sheet, select certain copper sheet quantity, be 40 in the number that is provided with of scale copper described in the present embodiment 23, the thickness of single scale copper 23 is 0.5mm.
Described lead wire 22 adds man-hour, adopts the copper sheet of many 0.5mm thickness, cuts out needed width, is bent into L shapedly then as required, stacks at last.
The lead wire 22 of above-mentioned coiling electric motor rotor lead wire structure is made up of several scale coppers that stack mutually 23, the quantity of described scale copper 23 can have the size of rotor current to calculate, not only be easy to bending, technology difficulty is little, shortened productive temp, and " kelvin effect " of rotor current reduction, copper consumption is few, has reduced production cost.
