Abstract
The invention relates to a motor rotor using an insert copper strip to replace an aluminum row for a refrigerating compressor, comprising an upper end ring, a lower end ring and a copper guiding strip, wherein the upper end ring and the lower end ring are provided with slots which are matched with the copper guiding strip, and the copper guiding strip is inserted into the slots of the upper end ring and the lower end ring and is connected with the upper end ring and the lower end ring to form the motor rotor. Compared with the prior art, by adopting a copper strip riveting mode to replace an aluminum casting mode, the invention saves energy, reduces emissions, reduces rotor loss by adopting the copper guiding strip and increases motor performance.
Description
Technical field
The present invention relates to a kind of rotor, especially relate to the motor used for refrigeration compressor rotor of a kind of plug-in type copper bar substitution of Al row.
Background technology
Existing squirrel-cage single-phase asynchronous motor rotor, adopts aluminum process more, complex process and and power consumption.In addition, aluminium resistivity is higher, and easily by aluminium ingot impurity effect, make rotor loss large, electric efficiency is low.This " characteristic " of cast-aluminum rotor, one of bottleneck having become restriction electric efficiency to improve.
Summary of the invention
Object of the present invention be exactly providing a kind of energy-saving and emission-reduction to overcome defect that above-mentioned prior art exists, reducing rotor loss, improving motor performance, motor used for refrigeration compressor rotor with plug-in type copper bar substitution of Al row.
Object of the present invention can be achieved through the following technical solutions: the motor used for refrigeration compressor rotor of a kind of plug-in type copper bar substitution of Al row, it is characterized in that, comprise top ring, lower loop and copper sliver, described top ring and lower loop are provided with the slotted eye matched with copper sliver, inserted by copper sliver in the slotted eye of top ring and lower loop, copper sliver is connected with top ring and lower loop and namely forms rotor.
Described copper sliver adopts rivet, hot jacket with the connection of top ring and lower loop or welds.
The manufacture employing rheo-die-casting of described top ring and lower loop is shaping or copper sheet riveting method is shaping.
Slotted eye on described top ring and lower loop is open slot or closed slot, and the flute profile of slotted eye can be parallel teeth, parallel slot, dovetail groove or double-cage rotor groove, and top ring and lower loop can exchange with assembling needs.
The shape of cross section of described copper sliver can be circle, triangle, square or polygon.
Compared with prior art, rotor copper sliver of the present invention and up and down end ring adopt slot fit, and copper sliver inserts in upper and lower side groove hole, after having assembled, assembly technology can be selected by riveting intensity, copper sliver and upper and lower side ring-shaped, size in conjunction with motor requirement, further refinement.Rotor balance weight, when manufacturing end ring, can the shaping or other riveting of rheo-die-casting, adopt copper bar riveting method to substitute cast aluminium, energy-saving and emission-reduction, adopt copper sliver, reduce rotor loss, improve motor performance.
