Abstract

A copper aluminum rotor for an ACC (Air Condition Compressor) comprises a rotor iron core formed by riveting an electromagnetic steel plate punching, a cast aluminum end ring, and an aluminum post for connecting with a counter balance, wherein a shaft hole for assembling a crankshaft of the ACC is formed in the middle of the rotor iron core; rotor slots are uniformly and radially distributed on the circumference of the rotor iron core; cast aluminum guide strips same with the rotor slots in shape are mounted in the part of rotor slots; copper guide strips are mounted in the rest of the rotor slots; and the copper guide strips and the cast aluminum guide strips are uniformly distributed in the rotor slots on the circumference of the rotor iron core at intervals. The cast aluminum rotor for the ACC provided by the utility model has the benefits that aluminum guide strips with low electric conductivity are replaced by the copper guide strips with high electric conductivity, the loss of a rotor winding is reduced, and the efficiency and the rotation speed of a squirrel-cage induction machine are improved. In addition, the copper guide strips and the rotor slots are in clearance fit to increase the resistance between the copper guide strips and the rotor iron core, so that the rotor loss caused by transverse current is reduced, the motor efficiency is further improved, and the cast aluminum rotor for the ACC can be produced via the present cast aluminum equipment when a little modification is made on the present production process.

Description

The copper aluminium rotor that a kind of compressor of air conditioner uses

Technical field

The utility model belongs to the Compressor Technology field, relates in particular to the mouse-cage type cast-aluminum rotor of compressor of air conditioner.

Background technology

Squirrel cage induction motor is simple because of manufacturing process, cost is low, the reliability advantages of higher, is widely used in compressor of air conditioner.When exploitation high energy efficiency compressor of air conditioner motor, adopt increase unshakable in one's determination long usually, low magnetic density falls; Improve copper factor, reduce modes such as stator winding resistance.Its deficiency is that electric machine iron core length increases, caused the increase of cage rotor aluminium sliver length, thereby has increased the proportion that the rotor winding loss accounts for the motor total losses.

Summary of the invention

The purpose of this utility model is to propose a kind of compressor of air conditioner copper aluminium rotor, and in the copper sliver insertion portion rotor that will be identical with the rotor grooved, all the other rotor bars and rotor end ring cast aluminium are made.

The technical solution of the utility model is: a kind of compressor of air conditioner copper aluminium rotor, comprise rotor core, cast aluminium end ring that electromagnetic steel plate punching riveted joint forms and the aluminium post that is used to connect balance weight, has the axis hole that is used for air conditioner compressed machine crankshaft assembling in the middle of the rotor core, be evenly distributed with rotor on the radial outside circumference, in a part rotor cast aluminium sliver identical with the rotor grooved is housed, the remainder that it is characterized in that described rotor is equipped with the copper sliver, and copper sliver and cast aluminium sliver are each other in the rotor that is evenly distributed on the rotor core circumference.

A kind of compressor of air conditioner described in the utility model copper aluminium rotor, it is characterized in that described copper sliver cast aluminium sliver in the rotor that is evenly distributed on the rotor core circumference each other, it is adjacent with a cast aluminium sliver that it is spaced apart a copper sliver, perhaps a copper sliver is adjacent with two cast aluminium slivers, and perhaps two each and every one copper slivers are adjacent with a cast aluminium sliver.

A kind of compressor of air conditioner described in the utility model is characterized in that with copper aluminium rotor the rotor core two ends are stretched out at the two ends of described copper sliver, and the part of stretching out the rotor core two ends is T-shaped or anti-L shaped, and extension is coated in the cast aluminium end ring.

A kind of compressor of air conditioner described in the utility model is characterized in that being matched in clearance between described copper bar and the rotor that the gap is between 0.05mm-0.1mm with copper aluminium rotor.

The beneficial effects of the utility model are: use the aluminium sliver of the copper sliver instead of part low conductivity of high conductivity, reduced the winding loss of cage rotor, improved efficiency of motor and rotating speed.And, further improved efficiency of motor because the existence in the less gap of copper sliver and rotor has reduced the loss that the rotor transverse current causes, and less to the production process change, existing cast aluminium equipment can be produced.

Description of drawings

The utility model has accompanying drawing 2 width of cloth, wherein

Fig. 1 is a copper aluminium rotor schematic diagram of the present utility model;

Fig. 2 is the radial section schematic diagram of Fig. 1 rotor.

Among the figure: 1 cast aluminium end ring, 2 bronze medal slivers, 3 rotor cores, 4 aluminium posts, 5 cast aluminium slivers, 6 axis holes
