The iron core has multiple the first ducts with the coaxial setting of the iron core, and the balance weight has and described the
The mounting hole that one duct is arranged in a one-to-one correspondence, a mounting hole being correspondingly arranged and first duct are a dress
Distribution group；
The connector is inserted in the pilot hole group, and axially disposed has through the second duct of the connector.
In the utility model embodiment, optionally, the balance weight is two, and described two balance weights are individually fixed in
Two end faces of the iron core.
In the utility model any embodiment, optionally, the motor rotor component further includes being set to the balance
Baffle between block and the iron core end face.
In the utility model embodiment, optionally, the connector is rivet arrangement connector.
In the utility model embodiment, optionally, second duct is round duct, or oval duct.
In the utility model any embodiment, optionally, second duct is helical duct.
In the utility model embodiment, optionally, second duct is ladder duct.
In the utility model any embodiment, optionally, the axis in second duct and the axis weight of the rivet
It closes.
In the technical scheme, by be used to fix motor balance weight and iron core connector it is axially disposed through connection
Second duct of part, i.e., set hollow structure for connector.Compared with prior art, solid by the connector of the technical program
After fixed, there are still through-holes for part of the motor for connector to be arranged, and the part can be made still to have through-flow effect in this way, to increase
The flow area for having added motor improves motor radiating rate, and reduces compressor oil content, improves the performance of compressor.

Specific embodiment
For the performance for improving motor radiating efficiency and compressor, the utility model embodiment provides a kind of motor turn
Sub-component.To keep the purpose of this utility model, technical solution and advantage clearer, the utility model is made by the following examples
It is further described.
As shown in Figures 1 to 5, motor rotor component provided by the embodiment of the utility model, including balance weight 1, iron core 2,
And balance weight 1 is fixed on to the connector 3 of 2 end face of iron core, in which:
Iron core 2 has multiple the first ducts 4 with the coaxial setting of iron core 2, and balance weight 1 has with the first duct 4 one by one
The mounting hole being correspondingly arranged, a mounting hole 5 being correspondingly arranged and first duct 4 are a pilot hole group；
Connector 3 is inserted in pilot hole group, and axially disposed the second duct 6 for having through-connections 3.
In the technical scheme, run through the connector 3 of the balance weight 1 for being used to fix motor and iron core 2 is axially disposed
Second duct 6 of connector 3, i.e., set hollow structure for connector 3.Compared with prior art, pass through the technical program
After connector 3 is fixed, there are still through-holes for part of the motor for connector 3 to be arranged, and the part can so still had through-flow
Effect, to increase the flow area of motor, improves motor radiating rate, and reduce compressor oil content, improves pressure
The performance of contracting machine.
As shown in Figure 1, optionally, balance weight 1 is two, and two balance weights 1 are solid respectively in the utility model embodiment
Due to two end faces of iron core 2.
As shown in Figure 1, in the utility model any embodiment, optionally, motor rotor component further include be set to it is flat
The baffle 7 to weigh between block 1 and 2 end face of iron core.
The work for avoiding the lubricating oil leakage of motor and environmental contaminants from entering motor can be played by the way that baffle 7 is arranged
With to make the more efficient of motor.
In various embodiments of the utility model, the concrete form of connector is unlimited, can be rivet arrangement connector, can also
Think the connector of the forms such as bolt, screw.
As shown in figure 3, optionally, the second duct 6 is round duct or slotted eye in the utility model embodiment
Road.
The technique control difficulty that the second duct 6 of connector 3 opens up can be effectively reduced in this way.
Further, as shown in figure 4, in the utility model embodiment, optionally, the second duct 6 is ladder duct.More
Further, as shown in figure 5, in the utility model any embodiment, optionally, the second duct 6 is helical duct.
By setting ladder duct or helical duct for the second duct 6, it can effectively increase by the second duct 6
Circulation area.At runtime, gas mixture will pass through a variety of circulation passages to compressor, so that it be made to flow through the path of motor more
Long, the obstruction being subject to is also more, and compressor oil return is more efficient, so that compressor oil content is lower, performance is more preferable.And
And the gas mixture for flowing through motor can also accelerate the cooling of motor, reduce the temperature rise of motor, to further increase the effect of motor
Rate.
As shown in Figures 1 to 5, in the utility model any embodiment, optionally, the axis in the second duct 6 and connection
The axis of part 3 is overlapped.
By the way that the axis in the second duct 6 is overlapped setting with the axis of connector 3, connector can be effectively improved in this way
3 structural stability improves the structural stability of motor so that balance weight 1 and iron core 2 effectively be riveted.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
