Abstract

The invention discloses a stator component, a motor and a compressor. The stator component comprises a stator core and a stator winding, wherein a plurality of stator teeth are arranged at intervals along the circumferential direction of a stator hole, and a winding groove is defined between any two adjacent stator teeth; the stator winding comprises a main winding and an auxiliary winding, and the main winding and the auxiliary winding penetrate through the winding grooves and are wound on the stator teeth. The secondary winding with the minimum span and the main winding are jointly arrangedin the same winding groove, the sum of the cross sectional areas of the copper wires of the main winding in the same winding groove is S1, the sum of the cross sectional areas of the copper wires of the secondary winding is S2, and S2 / (S1 + S2) is larger than or equal to 0.4 and smaller than or equal to 0.8. According to the stator component disclosed in the invention, as the secondary winding with the minimum span and the main winding are arranged to be in the same winding groove, the proportion of the secondary winding and the main winding in the same winding groove meets the condition thatS2 / (S1 + S2) is larger than or equal to 0.4 and smaller than or equal to 0.8, so that the proportion of the secondary winding in the common groove can be increased, the third harmonic content of the secondary winding can be reduced, and the motor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator component, a motor and a compressor. Background technique [0002] With the continuous improvement of energy efficiency requirements and the increasing cost of materials, improving the energy efficiency of motors and pursuing better cost performance are the technical directions that home appliance manufacturers need to pay special attention to. The commonly used winding distribution (main winding / secondary winding) of capacitor-operated compressors is 5 / 4, 5 / 3, 4 / 3 and other structures. In related technologies, in order to pursue high theoretical efficiency and reduce the harmonic content of the main winding, copper wires are usually used as much as possible for the main winding, and the number of layers of the main winding is more than that of the auxiliary winding. , the slot full ratio of the main winding is larger than that of the auxiliary winding, and is basically ...
