Insulation application of anti-leakage layers is set in 112, so as to avoid the conductivity issues between rotor core 11 and conductive bar 13, and then can be carried
The reliability of high rotor 100, reduce loss so that the efficiency of compressor 1000 and motor A provided with the rotor 100 significantly carries
It is high.Further, since application of anti-leakage layers also has the function of insulation, so that after the completion of die casting, without carrying out heat treatment (i.e. by rotor
The process that iron core 11 is deviate from from housing 400), therefore the abbreviation manufacturing procedure of rotor 100, improve the processing of rotor 100
Efficiency, and the structure of rotor 100 is simple, convenient processing.
In some embodiments of the invention, when conductive bar 13 be solid bar and inserting in rotor slot 112 when, rotor slot
112 at the cooperation of conductive bar 13 with being provided with insulating barrier.That is, can be in the inner surface and conductive bar 13 of rotor slot 112
Insulating barrier is set between outer surface.Here it is possible to understand, " insulating barrier " refers to the layer body with insulation function, and has
Have the layer body of insulation function can material selection be well known to those skilled in the art.
Thus, rotor 100 according to embodiments of the present invention, by being set at the cooperation of rotor core 11 and conductive bar 13
Insulating barrier with insulation function, so as to avoid the conductivity issues between rotor core 11 and conductive bar 13, and then can be with
Improve the reliability of rotor 100, reduce loss so that the efficiency of compressor 1000 and motor A provided with the rotor 100 significantly carries
It is high.
Preferably, insulate in application of anti-leakage layers and insulating barrier it is at least one be coating, coating is ceramic-like slurry coating, inorganic
It is at least one in coating and half organic half inorganic coating, that is to say, that coating be ceramic-like slurry, inorganic material and
The homogenous material layer of one of them either ceramic-like slurry, inorganic material and half organic half in half organic half inorganic material
The mixed material layer of multiple combinations in inorganic material.Thus, convenient to obtain, cost is low, and insulation effect is good.Moreover, the present embodiment
Coating except with insulation function also with heat insulating function, so as to further improve the reliability of rotor 100 and drop
Low energy consumption.
Certainly, the invention is not restricted to this, in other embodiments of the invention, insulating barrier can be other kinds of insulation
Forming layer, such as can also be (such as to be formed by peroxidization using being formed as chemically reactive layer by the way of chemically reacting
Oxide skin(coating)), can also using plating by the way of be formed as electrodeposited coating etc..Thus, convenient processing and acquisition.
Such as the present invention some preferred exemplaries in, when insulating barrier formed when on the inner surface of rotor slot 112, insulation
Layer can be coating or chemically reactive layer, and thus, convenient to process, exploitativeness is strong.And when insulating barrier is formed in conductive bar 13
Outer surface on when, insulating barrier can be coating, chemically reactive layer and electrodeposited coating etc..Thus, convenient processing, processing cost
It is low.
In some alternative embodiments of the present invention, when the die casting of conductive bar 13 is in corresponding rotor slot 112, conductive bar 13
It is molded with two integrated die-castings of Conducting end portions 12.Thus, it is possible to automatic mass production, and conductive bar 13 and Conducting end portions
12 connection is reliable, good conductivity.In the other alternative embodiment of the present invention, when conductive bar 13 is solid bar and inserting
