Abstract

A motor (100) applied to a rotary compressor and a compressor (200) having same. The motor comprises a stator (120) and a rotor (110). The stator comprises a stator iron core (121) and windings (130, 140, 150). The stator iron core is provided with a plurality of stator grooves (1211), and the windings are arranged in the stator grooves. Each stator groove only contains same-phase windings having the current in the same direction. The windings in each stator groove comprise first coils (131, 141, 151) and second coils (132, 142, 152). The end of each first coil and the end of each second coil are distributed in different stator grooves oppositely in the circumferential direction of the stator at certain pitch intervals.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a motor for a rotary compressor and a compressor having the same. Background technique [0002] In current mass-produced AC motors, when the windings in the same slot are in the same phase, the ends of the windings in each slot are set as one winding, and are distributed in the same stator slot in the same direction. The arrangement of the ends of the windings makes the cross-sectional area of ​​each winding larger. When the ends of the two-phase windings intersect, the interference space is larger, and the outer windings need to set up a larger space for the inner windings. For this reason, the outer windings need Set to a larger size to allow more headroom for the inner winding when shaping. [0003] At the same time, since the resistance of the multi-phase winding of the motor is required to be symmetrical in terms of electrical performance, the inner winding ...
