Abstract

The invention, which relates to the motor field, discloses a stator assembly, a motor and a compressor. The stator assembly comprises two stator portions. Each of the stator portions includes a yoke portion (1) and toothed portions (2); clamp grooves (11) extending axially are formed in the inner circumferential surface of the yoke portion; and protrusion portions (3) corresponding to the clamp grooves (11) are arranged at one axial end of each toothed portion (2). The two yoke portions (1) are aligned and are connected axially. The radial outer ends of the protrusion portions (3) of each stator portion are inserted into the clamp grooves (11) of the other stator portion correspondingly one by one. According to the invention, the stator assembly is formed by combination of the two stator portions and the toothed portions of the two stator portions are intersected in a circumferential direction; and enough space is formed between the adjacent toothed portions of each stator portion, so that a coil is wound simply and the efficiency is improved. Moreover, the yoke portions of the stator portions are integrated, so that the overall strength of the stator portion is enhanced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a stator assembly, a motor and a compressor. Background technique [0002] A compressor is an important part of refrigeration equipment, etc., and a motor is installed in it. The stator of the motor is a core component, wherein the stator includes an annular yoke and a plurality of teeth extending radially inward from the yoke, and the teeth are used to wind the coil. [0003] When winding the coil manually or using electrical equipment, the size of the notch between the ends of two adjacent teeth has a great influence on the winding speed. Generally, the larger the notch, the easier it is to wind the coil. However, the size of the notch also has a great influence on the electromagnetic performance of the stator. Too large a notch will lead to a large harmonic content of the magnetic field. Therefore, it is necessary to reduce the size of the notch as much as possible. [0004] At present...
