Abstract: The present invention provides a stator including a core having a plurality of core plates piled on one another, and a plurality of teeth formed in a regular interval on the circumference of the core. The stator also has a plurality of protuberant parts bent upward from outside to inside on one of the plurality of core plates. The stator further has at least one coil having winding parts wound on the teeth of the core and connecting parts hitched on the protuberant parts. The present invention allows simpler bending process of the core, with fewer molds, thus reducing the manufacture cost and the manufacture time to enhance productivity.
