Abstract

The invention relates to the field of motors and discloses a stator component, a motor and a compressor. The stator component comprises a stator yoke part (1), a connecting ring (3) and a plurality ofstator tooth parts (2), wherein the plurality of the stator tooth parts (2) are detachably sleeved with a support sleeve (5); a coil (4) which surrounds the stator tooth parts (2) is arranged on thesupport sleeve (5); the stator tooth parts (2) and the connecting ring (3) are capable of moving relative to the stator yoke part (1) in an axial direction; the radial outer ends of the stator tooth parts (2) and the stator yoke part (1) are connected in a mutually detachable manner. By adopting the technical scheme of the invention, the stator tooth parts and the stator yoke part are arranged ina mutually detachable manner, and the coils can be relatively easily arranged on the stator tooth parts before the stator tooth parts are mounted at the stator yoke part, so that the coil winding difficulties can be reduced, the problem of too large magnetic pressure reduction caused by too large intervals of tooth parts can be solved, and the problem of too large winding and torque pulsation canbe 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...
