[0002] The stator of the motor in the prior art adopts an integral stator core and a centralized winding, and an inner winding winding machine is used to wind the two salient poles opposite to each other on the diameter of the stator in a centralized winding manner. Compared with the traditional distributed winding stator, it saves materials, but its inner winding method through the notch seriously limits the running speed of the winding machine, resulting in low production efficiency of the single machine and high failure rate of the winding machine

[0003] Chinese invention patent 201110315032.7 discloses a capacitor-operated motor stator and its manufacturing method. The stator core adopts a split stator core. The manufacturing process is characterized by split combination and then cutting and separation. The winding adopts the method of pre-winding and then assembling and integrating. ; This stator manufacturing method has certain defects: the pre-winding process of the winding is the same as the manufacturing process of the shaded pole asynchronous motor. On the core, the process must be done manually, resulting in low production efficiency and high scrap rate, so we designed a capacitor-operated motor stator and its manufacturing method to solve the above problems
