Stator core, motor, assembly method and compressor

Abstract

The invention discloses a stator core, motor, assembly method and compressor. The stator core presents the separated structure including primary structural unit and secondary structural unit. The primary structural unit and secondary structural unit form the stator core through connection in radial direction. The stator core adopts the separated structure and is formed by connection of two structural units in radial direction.On one hand, the connection can be performed after respective wire wrapping of two structural units to facilitate the wire wrapping operation, improve the space factor, shorten the overall size of motor, reduce the motor weight, decrease the cost and improve the motor performance; on the other hand, during the assembly,the active cell may be firstly installed and then the structural units are installed at both sides of active cell, so that the size of active cell stand will not be limited. The size of active cell stand may be increased to improve the motion reliability of active cell.

Description

technical field [0001] The invention relates to the field of motors, in particular to a stator core, a motor, an assembly method and a compressor. Background technique [0002] The existing stator core is a complete structure in a plane perpendicular to its axis, such as figure 1 As shown in , it includes an overall frame-shaped structure 11' and two opposite magnetic pole teeth 12' arranged in the frame-shaped structure 11'. A space is formed between the end faces of the two magnetic pole teeth 12'. Mover 2'. The existing stator core has the following problems: [0003] 1. The winding process of the winding on the pole teeth is difficult, and the slot fullness rate is low, which affects the thrust of the motor using it and causes the overall volume of the motor; [0004] 2. The mover is generally installed on the mover bracket. When the width of the mover bracket is greater than the distance between the end faces of the two magnetic pole teeth, the mover cannot be instal...
