Abstract

The invention discloses a stator, a single-phase induction motor, a compressor and a refrigeration device. The stator comprises a stator iron core provided with multiple stator slots, and primary windings and auxiliary windings which are wound in the multiple stator slots to form two poles; 28 stator slots are provided and each stator slot comprises multiple first stator slots and multiple secondstator slots with the radial depth greater than that of each first stator slot; the first to eight groups of the multiple stator slots are distributed in the circumferential direction of the stator iron core in sequence; the first group of the stator slots, the third group of the stator slots, the fifth group of the stator slots and the seventh group of the stator slots comprise two first stator slots, respectively; the second group of the stator slots and the sixth group of the stator slots comprise four second stator slots; the fourth group of the stator slots and the eighth group of the stator slots comprise six second stator slots; and the peripheral surface of the stator iron core is provided with tangent sides corresponding to the first stator slots.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a stator, a single-phase induction motor, a compressor and refrigeration equipment. Background technique [0002] In the related art, in a compressor used in a refrigeration device such as an air conditioner, the driving component in the compressor is an electric motor, and the electric motor usually adopts a brushless DC motor or an induction motor. [0003] For a compressor using a single-phase induction motor, the single-phase induction motor usually includes: a stator winding composed of a main winding and an auxiliary winding connected in series with a running capacitor with a coil angle of 90 degrees from the main winding, and the rotor is generally a squirrel-cage type. Cast aluminum construction. The number of stator slots of existing single-phase induction motors is generally 20, 24, etc. The design of the number of stator slots is relatively old and cannot improve ...
