Problems solved by technology

[0008] figure 2 The motor rotor balance weight of the structure shown plays an important role in increasing the rotor torque and maintaining the dynamic balance of the rotor. However, since the balance weight is made of copper, the amount of copper used in the balance weight of the prior art with the above structure is too large, which increases the Component material costs for compressor motor production

Embodiment Construction

[0023] Now further illustrate specific embodiments of the present invention in conjunction with accompanying drawings.

[0024] image 3 It is an improved structural diagram of the motor rotor balance weight of the present invention. Such as image 3 As shown, the balance weight of the motor rotor of the compressor involved in the present invention is an arc-shaped body, which is integrally formed by the upper protrusion 5b and the lower bottom bracket 6b. Both ends of the bottom bracket 6b protrude inwardly. Both ends of the bottom bracket 6b protrude toward the inner side, and the end faces are protruding surfaces, and a through hole 7b is provided in the center of the protruding portion. The bolt passing through the through hole 7b fixes the balance weight on the rotor of the motor.

[0025] The inner arc surface 8b of the bottom bracket 6b is connected with the inner arc surface 9b of the protrusion 5b, and the inner arc surface of the bottom bracket 6b and the protrus...

Abstract

This invention discloses one compressor motor rotor balance block improve structure in arc shape composed upper bench and down bottom bench. Through reducing bottom rack height, it reduces gravity transfer of balance block to reduce quality and copper materials volume.

Description

technical field [0001] The invention relates to a compressor, in particular to a balance weight of a compressor motor rotor. Background technique [0002] Compressors are important components of household appliances such as air conditioners and refrigerators that use the refrigeration cycle system to work. Driven by the motor, the moving piston (rolling piston or reciprocating piston) of the compressor converts mechanical energy into pressure energy to compress the refrigerant in the compressor cylinder. The motor converts electrical energy into rotational mechanical energy through the rotation of the corresponding components under the action of the current magnetic field to provide power for the operation of the compressor. Therefore, the motor is an important part of the compressor, and its operating performance directly affects the function of the compressor. [0003] Generally speaking, the motor is composed of two parts, the stator and the rotor, and the stator and th...
