Abrégé
(EN)
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.
