Abstract
This unity model is macro rat cage asynchronous motor rotor, relating to asynchronous motor, in particular to an asynchronous motor rotor. This unity model solved the problem of casting defects appearance because of adopting casting aluminum rotor winding, which affect the rotor yield rate, motor rotating diference rate, and motor efficiency, and the problem of using high fault rate and adopting whole round coining for rotor impact tablet, which waste too much and cost high. This macro rat cage asynchronous motor rotor includes shaft, rotor iron core, rotor winding, rotor stent being fixed on the shaft, fan-shaped impact tablet being adopted for iron core, whole round being fixed on the rotor stent, and rotor winding consisting of copper conducting bar, both ends of copper conducting bar, and copper ending ring of copper conducting bar. This unity model is of resonable design and safe and reliable application. With the using of the big asynchronous motor, especially the extension and application in electric driving technology, the micro rat cage asynchronous motor rotor will be applicated extensively.
Description
Technical field
The utility model relates to asynchronous machine, and particularly the rotor of asynchronous machine is specially large-scale squirrel cage asynchronous motor rotor.
Background technology
Large-scale asynchronous motor needs large-scale cage rotor.The cage rotor winding divides cast aluminium and two kinds of structures of copper bar usually.Do not see at present the report that on large-sized asynchronous motor, uses copper sliver cage rotor winding.And the cast-aluminum rotor winding is prone to casting flaw, influences rotor rate of finished products and performance parameters such as motor slip ratio, efficient, operational failure rate height, and it is particularly outstanding that these show on large-scale cage rotor.The rotor punching of existing large-scale cage rotor adopts the full circle punching out, and waste is big, and cost is higher, does not see the report that uses segmental punching on the rotor of large-sized asynchronous motor at present.
Summary of the invention
The utility model adopts the cast-aluminum rotor winding to be prone to casting flaw in order to solve large-scale cage rotor, influence rotor rate of finished products and performance parameters such as motor slip ratio, efficient, operational failure rate height and rotor punching adopt the full circle punching out, waste is big, cost provides a kind of novel large-scale squirrel cage asynchronous motor rotor than problems such as height.
The utility model is to adopt following technical scheme to realize: large-scale squirrel cage asynchronous motor rotor, comprise rotating shaft, rotor core, rotor winding, be fixed with rotor field spider in the rotating shaft, segmental punching is adopted in rotor core, full circle is pieced together solid on rotor field spider, and the rotor winding is made of with the copper end ring that the soldering of copper sliver is connected copper sliver, copper sliver two ends.By rotor field spider is set, when saving rotor punching, can satisfy the large diameter needs of large-scale cage rotor; Rotor core adopts segmental punching further to save material, reduced cost; Copper sliver cage rotor has overcome the defective of cast-in aluminum squirrel cage rotor.
Large-scale squirrel cage asynchronous motor rotor described in the utility model had both adopted segmental punching, adopted the copper sliver again, had replenished the blank of large-scale squirrel cage asynchronous motor rotor, and its reasonable in design is safe and reliable.Along with the use of large-size asynchronous motor, progressively applying in direct electric Driving technique particularly, this large-scale squirrel cage asynchronous motor rotor will be used widely.
