Abstract

The utility model relates to a novel squirrel-cage copper bar asynchronous motor rotor which comprises a copper bar which is arranged in a squirrel-cage motor rotor core, a left copper end ring, a right copper end ring, and a copper ring used for press-mounting and welding. The novel squirrel-cage copper bar asynchronous motor rotor has the advantages of smaller volume, higher motor efficiency, simplified processing and manufacturing processes and reduced production and manufacturing costs.

Description

A kind of new type squirrel-cage copper sliver asynchronous machine rotor

Technical field

The utility model relates to a kind of squirrel cage motor, especially relates to a kind of new type squirrel-cage copper sliver asynchronous machine rotor.

Background technology

For squirrel cage motor, mostly traditional approach is to adopt cast aluminium to make rotor, and the cast aluminium sliver is set in the slotted eye of rotor, thereby makes electric current form the loop in rotor, but because the resistivity of aluminium is higher, so rotor loss is big, causes electric efficiency to reduce; Based on the cast aluminium material of end ring, sliver and the motor of syndeton thereof, make overall volume bigger, cause required working space bigger; In addition, the motor of this structure needs special-purpose cast aluminium equipment, complex process, and increased production cost.

Summary of the invention

The utility model mainly is to solve the technical problem that the existing in prior technology rotor volume is big, complex process needs special equipment, and a kind of new type squirrel-cage copper sliver asynchronous machine rotor is provided.A kind of new type squirrel-cage copper sliver asynchronous machine rotor, comprise copper sliver, the left and right sides copper end ring of squirrel cage motor rotor core setting and the steel loop that is used for press-fiting welding, make rotor volume less, electric efficiency is higher, and can simplify process for machining and manufacturing, reduce manufacturing cost.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of new type squirrel-cage copper of the utility model sliver asynchronous machine rotor, it comprises rotor core and is located at the left end ring at its two ends, right-hand member ring, this rotor core is provided with a circle sliver hole, the hole is built-in with the sliver that is connected with the right-hand member ring with the left end ring, the material of described left end ring and right-hand member ring is a steel, its inboard is respectively equipped with the copper ring that end face is resisted against the rotor core sidewall, copper ring offer the through hole corresponding with sliver hole on the rotor core and with constitute with sliver and be connected; Described sliver material is a copper, its two ends be sheathed on respectively with left end ring and right-hand member ring in the adaptive with it hole and be welded as a whole.Adopt lower copper sliver, the copper ring of conductance, can make electric efficiency higher, simultaneously also make rotor have smaller volume, the rotor of smaller size smaller makes the motor overall volume less, make the motor miscellaneous part therefore obtain smaller volume, that is reduce the material consumption of each parts, thereby reduced the material cost of other parts of motor indirectly; Copper sliver and left and right sides end ring are welded to connect and are integral, copper ring compresses by left and right sides end ring, and this structural manufacturing process is simple, need not special-purpose Casting Equipment, thereby has reduced manufacturing cost.

As preferably, it is counter sink that described left end ring is equipped with the hole that is connected with sliver with right-hand member, and the small end of this counter sink is sheathed on the sliver, big end is the sliver weld part.The redundant space of big end can hold the sliver after the fusing, forms riveted structure.

As preferably, the both ends of described sliver and left end ring and right-hand member ring adopt the copper fusion welding.To keep weld part to have higher structural strength and electrical efficiency.

As preferably, the length that steel left end ring and right-hand member ring are inserted in described sliver both ends is the 1/4-3/4 of the height of corresponding aperture on left end ring and the right-hand member ring.Make weld seam can place the hole of left and right sides end ring, be beneficial to protection welding position, outward appearance neat appearance.

Therefore, the utlity model has rational in infrastructure, be easy to characteristics such as manufacturing, especially have beneficial effects such as electrical efficiency is higher, volume is less, technology is simple, need not special-purpose Casting Equipment, manufacturing cost is low.
