Problems solved by technology

[0003] Low-frequency noise from 10Hz to 500Hz is the focus of rotary compressors at present. Developers are looking for reasonable improvement directions and methods. However, the existing built-in expansion chamber mufflers cannot effectively reduce low-frequency noise from 10Hz to 500Hz.
The frequency conversion compressor has high noise at high speed, and it is difficult to solve
The low noise requirement of the inverter compressor makes the existing noise reduction methods such as built-in mufflers unable to meet, and a new method is required

Abstract

The invention provides a motor insulation support and a compressor, and the motor insulation support comprises an annular support body, and a first end and a second end are formed in the axial direction of the annular support body; the multiple winding teeth are connected to the inner wall of the annular support body, and each winding tooth comprises a radial part and an axial part which are connected with each other, and the axial part extends towards the first end; the sound absorption plate surrounds the periphery of the annular support body, and a plurality of sound absorption holes are formed in the surface, facing the first end, of the sound absorption plate. The noise generated when a refrigerant passes through can be effectively reduced by additionally arranging the perforated sound absorption structure on the insulating support, and the noise reduction requirement is met through sound absorption.

Description

technical field [0001] The invention relates to the field of noise reduction of compressors, in particular, to an insulating bracket of a motor and a compressor. Background technique [0002] At present, due to the wide application of electricity, motors can be used in all aspects of daily life and industrial production. Motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction. The main function of the motor is to generate driving torque as a power source for electrical appliances or various instruments. [0003] The low-frequency noise from 10Hz to 500Hz is the focus of the current rotary compressor. Developers are looking for reasonable directions and methods for improvement, but the existing built-in expansion chamber muffler cannot effectively reduce the low-frequency noise from 10Hz to 500Hz. The inverter compressor has high noise at high speed, and it is difficult to s...
