Problems solved by technology

However, in the existing structure, the compressor is a pulsating load. During the low-frequency operation of the compressor, the speed fluctuates greatly. Due to the small inner diameter of the stator of the motor part, the anti-disturbance ability of the rotor under low-frequency conditions is poor, resulting in low-frequency energy efficiency of the compressor. suppressed

Abstract

The invention provides a motor used for a compressor. The motor comprises a stator and a rotor, wherein the stator comprises a stator iron core which adopts an annular cylinder shape; the ratio k of the inner diameter to the outer diameter of the stator iron core is greater than 0.5; the rotor is arranged in a columnar space defined by the stator iron core; the rotor comprises a rotor iron core and a magnetic part; the magnetic part is arranged on the rotor iron core; the displacement V of the compressor, the quality M of the rotor iron core and the magnetic part, and the maximum outer diameter R of the outer edge of the rotor satisfy that V / (M*R<2>)*1000 is greater than 2 and less than 4, wherein the unit of the displacement V of the compressor is cm<3>; the unit of the quality M of the rotor iron core and the magnetic part is g; and the unit of the maximum outer diameter R of the outer edge of the rotor is cm. By virtue of the motor provided by the invention, the miniaturization of the motor can be ensured, rotary speed fluctuation is reduced, the operational stability of the compressor in low-frequency operation process is improved effectively, the complete machine energy efficiency of the compressor is improved, and the noise of the compressor is lowered.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a motor, a compressor and a refrigeration device. Background technique [0002] As we all know, the single-cylinder rolling rotor compressor has a simple structure and high energy efficiency, and is widely used in the fields of air conditioners and other household appliances. However, in the existing structure, the compressor is a pulsating load. During the low-frequency operation of the compressor, the speed fluctuates greatly. Due to the small inner diameter of the stator of the motor part, the anti-disturbance ability of the rotor under low-frequency conditions is poor, resulting in low-frequency energy efficiency of the compressor. suppressed. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, a first aspect of the invention consists in proposing ...
