<p>An electric motor stator of capacitive operation type and a manufacturing method therefor. The stator thereof comprises a stator core, a main winding and a secondary winding, wherein the stator core is a split unit stator core formed by connecting an independent ring-shaped magnetic yoke and 2n independent protruding polar parts via a mortise-tenon structure, with n>=2; each of the protruding polar parts is encased by an independent insulating winding sheath; and the main winding is wound on n insulating winding sheaths in a spaced manner, and the secondary winding is wound on the remaining n insulating winding sheaths in a spaced manner. The electric motor stator of capacitive operation type is manufactured by assembling split units and then cutting and separating. The electric motor stator of capacitive operation type manufactured by this method has a rational and scientific structure, and winding and assembly are convenient and highly efficient. Moreover, since it is manufactured by assembling and integrating after winding, many restrictions due to the necessity of winding through slot apertures in conventional stators are removed, thereby greatly increasing the efficiency of winding and enabling the width of the slot apertures to be configured as required, thus increasing the performance of the electric motor.</p> |
