摘要： A stator structure, including strip shaped stator cores and end insulators. The end insulators are injection molded with the strip shaped stator cores, as a whole. A wire duct is arranged on top of a yoke of each strip shaped stator core and at the bottom of each end insulator. Two ends inside the wire duct are projected with bosses. Coil windings wind around the bosses and pass through the wire duct. The stator structure is simple and easy to mass produce. It can make full use of the slot filling ratio of the strip shaped stator. The invention solves the puncture problem.
