Compressor stator, compressor and manufacturing method thereof

Abstract

The invention provides a compressor stator, a compressor and a manufacturing method thereof. The compressor stator comprises multiple T-like iron cores which are mutually combined annularly; each T-like iron core is wound by a winding; each T-like iron core comprises a tooth part and a pair of connecting arms integrally extending from two sides of the first end of the tooth part respectively; thewinding corresponding to each T-like iron core performs winding along the tooth part of the T-like iron core; the winding passes through two included angle areas formed by two sides of the tooth partand the two connecting arms; the end part of the connecting arm is provided with at least one connecting tenon and / or at least one connecting slot; and two adjacent T-like iron cores are connected through the connecting tenons and / or the connecting slots. Through blocked individual winding, a winding pin can be prevented from occupying a stator slot, and in comparison with the traditional centralized winding motor, the motor slot filling rate Spf can be greatly improved, and optimization of the motor performance is further achieved.

Description

Technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a compressor stator, a compressor and a manufacturing method thereof. Background technique [0002] At present, the permanent magnet synchronous concentrated winding motor used in the DC inverter compressor has an integral structure of the stator punch and adopts round enameled wire winding. [0003] Such as Figure 1 to 4 Shown. A compressor in the prior art includes: an upper cover 1, a housing 2, a motor 3, an upper cylinder head 4, a cylinder 5, a lower cylinder head 6, a lower cover 7, and an accumulator 8. Among them, the motor 3 and the cylinder 5 are housed in the housing 2. The motor 3 includes a rotor 32 and a stator 33; the crankshaft 31 transmits the rotational force of the motor 3 to the piston in the cylinder 5 to compress the refrigerant; the upper cylinder head 4 and The lower cylinder head 6 and the cylinder 5 jointly define the compression space and support the ...

AI Technical Summary

Problems solved by technology

The stator 33 needs to stretch into the stator slot 334 for winding due to the winding needle (not shown) when winding, so that the winding needle occupies the area of ​​the part stator slot 334; 333) arrangement leads to gaps between the enameled wires, which further reduces the area of ​​the stator slot, making the effective area of ​​the stator slot lower and affecting the performance of the motor
