Abstract
The present utility model relates to a motor copper bar rotor. The rotor comprises a rotor iron core, conducting bars and an end ring, a ring-shaped groove is arranged on the end ring, the conducting bars are arranged inside the groove, the rotor also comprises filling sheets, and the filling sheets are arranged between the two neighboring conducting bars. By adopting the rotor, problems that large gaps exist between the motor rotor conducting bars of the prior copper bar rotor, and welding flux is wasted when the conducting bars are welded can be solved. Under the prerequisite of guaranteeing welding quality, the use of welding flux is reduced, and motor production costs are reduced.
Description
Technical field
The utility model relates to a kind of rotor of three-phase cage rotor electric machine.
Background technology
Three-phase cage copper bar rotor motor, rotor are to be assembled (like Fig. 1) by rotor core 4, sliver and end ring, and wherein end ring and sliver adopt and be welded to connect.During welding, there is big gap (as shown in Figure 2) owing to have on the end ring between annular groove and the every sliver of dark 3mm, thereby needs the expensive silver solder of labor, cause unnecessary waste.
Summary of the invention
There is big gap between the existing copper bar rotor motor rotor conducting bar in order to solve; The media problem of waste scolder during the welding sliver, the utility model provides a kind of copper bar rotor of motor, under the prerequisite that guarantees welding quality; For reducing the use of scolder, reduce the motor production cost.
The technical solution of the utility model:
A kind of copper bar rotor of motor comprises rotor core, sliver and end ring, and said end ring is provided with annular groove, and said sliver is arranged in the groove, and its special character is: also comprise filler piece, said filler piece is arranged between adjacent two slivers.
Above-mentioned filler piece is copper, and thickness is 3mm.
The advantage that the utility model had:
1, the rotor that is provided of the utility model is provided with filler piece between sliver and sliver, has reduced the gap between the sliver, has saved scolder.
2, the filler piece thickness of the utility model is 3mm, saves material, and convenient the installation can be found out from all scolder contrasts of Fig. 2 and Fig. 3.
Description of drawings
Fig. 1 is the structural representation of existing rotor;
Fig. 2 is the assembling sketch map between existing sliver and the sliver;
Fig. 3 is the structural representation of the utility model rotor;
Fig. 4 is the assembling sketch map between the utility model sliver and the sliver;
Wherein Reference numeral is: 1-sliver, 2-end ring, 3-filler piece, 4-rotor core, 5-scolder.
Embodiment
As shown in Figure 3, a kind of copper bar rotor of motor comprises rotor core, sliver 1 and end ring 2, and end ring is provided with annular groove, and sliver is arranged in the groove, also comprises filler piece 3, and filler piece is arranged between adjacent two slivers.General filler piece is copper, and thickness is 3mm.When welding end ring, sliver, earlier sliver is inserted in the end ring annular groove,, then filler piece is placed between each sliver gap, with silver solder all slits are filled up again and welded like Fig. 4.
Claims (2)
1. the copper bar rotor of a motor comprises rotor core, sliver and end ring, and said end ring is provided with annular groove, and said sliver is arranged in the groove, it is characterized in that: also comprise filler piece, said filler piece is arranged between adjacent two slivers.
2. the copper bar rotor of motor according to claim 1, it is characterized in that: said filler piece is copper, thickness is 3mm.
