Abstract:
A stator core of a torque motor comprising:a plurality of stator core divided bodies fabricated from a sheet metal material, each stator core divided body including an arm portion for pressure inserting a coil portion and a pole tooth portion forming an arc-shaped surface and arranged in a columnar space for inserting a rotor in an opposing manner, wherein a stator core entire body having a front entire shape of the stator core, being fabricated from a sheet metal material and a pair of the stator core divided bodies divided as two individual pieces are connected in a facially-opposing overlapping manner, said pair of stator core divided bodies are arranged in both sides so as to be provided with a space portion therebetween and oppose the pole tooth portions to each other such that the arc-shaped surfaces of each respective pair of stator core divided bodies facially-oppose each other, and a portion in the vicinity of said space portion of said stator core entire body connects said stator core divided bodies in both sides as a connection portion and is integrally formed.
