Stepping motor and manufacturing method thereof

摘要

A method of manufacturing a stator member for a stepping motor of the present invention comprises the steps of: placing a coil member on a mold; placing a yoke member on a mold with its teeth portions being inserted into a cylindrical hollow portion of the coil member from its one end, one surface of each of the teeth portions facing the mold being in contact with a surface of the mold; pressing the yoke member toward the coil member in a direction along the central shaft portion of the coil member so that a base plate portion of the yoke member may be brought into contact with a flange portion of the coil member; and providing hardenable material in a space enclosed by the surface of the mold and surfaces of the coil member and the yoke member, to thereby integrally uniting the coil member and the yoke member into one stator member.
