Abstract
A stator core of the invention is structured such that the stator core is provided with an arm portion for pressure inserting a coil portion, and pole tooth portions arranged in a columnar space for inserting a rotor in an opposing manner. In the stator core, a stator core entire body having a front entire shape of the stator core and a pair of stator core divided bodies approximately divided into two pieces are connected in an overlapping manner. A pair of stator core divided bodies are arranged in both sided so as to be provided with a space portion therebetween and oppose the pole tooth portions to each other, and a portion in the vicinity of the space portion of the stator core entire body connects the stator core divided bodies in both sides as a connection portion and is integrally formed. In accordance with the stator core, it is possible to improve an assembling workability at a time of manufacturing without generating reduction of a generation torque.
