Size reduction, but it is so too loose between copper bar and groove can influence to radiate, and copper bar loosens in the running, easily makes
Copper bar is broken, and can also make occur electric spark phenomenon between copper bar and iron core on startup.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of copper bar rotor.
The present invention is achieved by the following technical solutions.
A kind of copper bar rotor, including rotating shaft, rotor key, wherein the rotor punching for being provided with rectangular channel laminates into a cylinder
Shape, the alignment of all rectangular channels, rotor core is formed, the rotor copper of the rectangle to match therewith is passed through in rotor core rectangular channel
Row, copper bar rotor stretch out the rotor core each 50-70mm in both ends, and rotor end ring is gear-like, is engaged with copper bar rotor, by rotor
In tooth on copper bar insertion rotor end ring, the space of two V-arrangements can be formed in rotor bar both sides, the space of the V-arrangement is weldering
The groove connect, after all copper bar rotors and rotor end ring welding, an entirety is formed, in the both ends U-lag of copper bar rotor
Interior, without latitude band, blend compounds are adhesively fixed firmly ring-wound, ensure the operating resistance to overturning of copper bar rotor.
Specifically, above-mentioned rotor end ring top is stepped tooth.
Specifically, the welding method of above-mentioned copper bar and rotor end ring upper trapezoid tooth is the method for pressure welding.
Specifically, above-mentioned no latitude band is polyester fiber material.
Technical scheme more than, the beneficial effects of the invention are as follows：
Copper bar rotor provided by the invention, assembling process is simple and easy, is tightly combined between copper bar and groove, then passes through welding
Processing, effectively solves the problems, such as the loosening between copper bar and groove, improves integrally-built mechanical strength, and radiating effect
Significantly, improve the operating efficiency of motor and extend the service life of motor；In the both ends U-lag of copper bar rotor, annular
Without latitude band, blend compounds are adhesively fixed firmly, ensure the operating resistance to overturning of copper bar rotor for winding；Copper bar rotor stretches out rotor
Each 50-70 ㎜ in both ends unshakable in one's determination, the both ends of rotor core form two centrifugal fans again when rotor rotates, and improve overall radiating
Performance.
