Abstract

The invention belongs to the motor field and discloses a stator assembly, a motor and a compressor. The stator assembly comprises a stator yoke portion (1), a connecting ring (3) and a plurality of stator tooth portions (2); the stator tooth portions (2) are provided with a coil (4) surrounding the stator tooth portion portions (2); the radial outer ends of the stator tooth portions (2) are provided with stopping portions (22); the stator tooth portions ( 2) and the connecting ring (3) can axially move relative to the stator yoke portion (1); and the stator tooth portions (2) are detachably connected with the stator yoke portion (1). With the above technical schemes of the invention adopted, the stator tooth portions and the stator yoke portion can be detachable from each other; the coil can be disposed on the stator tooth portions more easily before the stator tooth portions are mounted on the stator yoke portion; the winding difficulty of the coil can be reduced; excessive magnetic pressure drop caused by excessively large tooth intervals can be avoided; and winding problems and the problem of excessive torque ripples can be solved.

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] In the motor of the compressor, the stator and the rotor are the core components. The rotor is set in the center hole of the stator. After the coil of the stator is energized, the rotor can be driven to rotate by electromagnetic induction, thereby driving the piston to rotate. The stator includes a plurality of teeth disposed around the rotor, each tooth extends radially, and a coil is wound on each tooth, and the coil is energized to generate a magnetic field. Multiple teeth are arranged along the circumferential direction, and the slot width between adjacent teeth has a great influence on the performance of the motor and the difficulty of winding. Generally, in order to facilitate winding, the slot of the stator is often made wider, and the slot that is too wide will cause a large magnetic pressure drop when the m...
