Stator component of permanent magnet motor for refrigerator compressor and refrigerator compressor

Abstract

The invention discloses a stator component of a permanent magnet motor for a refrigerator compressor and the refrigerator compressor. The stator component is a three-phase six-slot structure and comprises a stator core and six windings. The stator core is provided with six wire slots along a circumferential direction, and a wire winding tooth is arranged between every two adjacent wire slots. The six windings are wound on the six wire winding teeth in a one to one corresponding way, and two windings on two wire winding teeth in a central symmetry are connected to form a phase. According to three phases of windings, wires enter from three continuous wire winding teeth in the six wire winding teeth, according to the other three phases of windings, wires leave the other three wire winding teeth in the six wire winding teeth, and wire inlet starting point ends and wire outlet ending point ends of the three phases of windings are at the same axial side of the stator core. According to the stator component of a permanent magnet motor for a refrigerator compressor of the embodiment of the invention, since the three wire inlet starting point ends and the three wire outlet ending point ends of the three phases of windings of the stator component are arranged in an adjacent way, the winding difficulty of the stator component is reduced, and the manufacturing efficiency of the stator component is improved.

Description

technical field [0001] The invention relates to the field of compressor equipment, in particular to a stator part of a permanent magnet motor for a refrigerator compressor and the refrigerator compressor. Background technique [0002] In the manufacturing process of the stator part of the frequency conversion motor used in the refrigerator compressor, the insulating end plate is required to meet the insulation requirements of the stator core and the winding magnet wire. The incoming wire end and outgoing wire end of the winding magnet wire need to be led out or shorted through the outgoing wire end and neutral end on the insulating end plate. Therefore, the positions of the outlet terminal and the neutral terminal determine the coil length and winding method of the motor. During the winding process of the stator part, the sliding of the magnet wire inlet end and the insulating end plate may cause the magnet wire to be broken due to excessive force, resulting in low product ...
