Description
Technical field
The present invention relates to a kind of part of motor, more particularly to a kind of motor copper rotor.
Background technology
Existing motor copper rotor is after copper bar is worked into definite shape and size, copper bar to be squeezed into rotor core by extrusion process, is fitted close with rotor slot shape, and copper end ring is connected with copper bar by welding manner.The degree requirement that the structure coordinates copper bar and rotor slot shape is very high, will otherwise cause the phenomenon of copper bar play in groove, and hidden danger is brought to motor longtime running, and the reliability standard of this kind of copper rotor is low.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided one kind avoids copper bar play in sliver groove, the high power motor copper casting rotor of good reliability.
The present invention is achieved through the following technical solutions technical goal.
High power motor copper casting rotor, including rotor core；The rotor core is overrided to form by some size shape identical rotor punchings；Axis hole is provided with the middle part of the rotor punching, some sliver holes are uniformly distributed on peripheries with, the sliver hole phase poststack in each rotor punching is linked to be the sliver groove in rotor core；Copper sliver is provided with the sliver groove, the two ends of rotor core are provided with copper end ring, and copper end ring is fixedly connected on the two ends of copper sliver；It is theed improvement is that：Sliver groove is helicla flute in the rotor core that sliver hole phase poststack is linked to be in the rotor punching；The spiral helicine copper sliver of insertion in the sliver groove.
In said structure, two ends copper end ring and the copper sliver die casting that die casting has copper sliver, rotor core in the sliver groove link together.
In said structure, on the outer face of the copper end ring and along the uniform some grooves of diametric(al) of copper end ring.
The present invention compared with prior art, has the positive effect that：
1st, sliver groove is helicla flute in the rotor core that sliver hole phase poststack is linked to be in rotor punching, and the spiral helicine copper sliver of insertion, so, it is to avoid copper bar play in sliver groove, significantly improves reliability of the invention in sliver groove.
2nd, die casting has copper sliver in sliver groove, the two ends copper end ring of rotor core links together with copper sliver die casting, realize the integral structure of rotor bar and end ring, the reliability of motor rotor and service life are greatly improved, is highly suitable for the place higher to reliability requirement.
3rd, on the outer face of copper end ring and along the uniform some grooves of diametric(al) of copper end ring, when the rotor is turning, copper end ring can play a part of cooling wind blade, can save the design of cooling wind blade, while also reducing the usage amount of copper, reduce the cost of rotor.

Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is Fig. 1 left views.
Fig. 4 is rotor punching structure schematic diagram in the present invention.
Specific embodiment
The invention will be further described below according to accompanying drawing and in conjunction with the embodiments.
High power motor copper casting rotor shown in the drawings, including rotor core 1；Rotor core 1 is overrided to form by some size shape identical rotor punchings 2；The middle part of rotor punching 2 is provided with axis hole, it is uniformly distributed on peripheries with 14 sliver holes 2.1, the phase poststack of sliver hole 2.1 in each rotor punching 2 is linked to be the sliver groove in rotor core 1, sliver groove is helicla flute, die casting has spiral helicine copper sliver 3 in sliver groove, the two ends of rotor core 1 are provided with copper end ring 4, and the two ends copper end ring 4 of rotor core 1 links together with the die casting of copper sliver 3.
On the outer face of copper end ring 4 and along uniform 8 grooves 5 of diametric(al) of copper end ring 4.
