Abstract

A method of molding a resin casing covering a stator of a motor may include preparing first and second molds; disposing the stator in the first mold; combining the molds; pouring a resin into the cavity; curing the resin; separating the molds; and taking the stator and resin casing from the mold. The stator may include a core, an insulator, and a coil. The core may include a core back surrounding and teeth that extend inward from the core back. The insulator may include wall portions inside the coil. The wall portions may be provided around the teeth and extend toward one side in an axial direction. One of the molds may include cylindrical surfaces contacting inner end faces of the teeth. The first mold may include wall supporting surfaces contacting or facing the inner surfaces of the wall portions. The wall supporting surfaces may be outside the cylindrical surfaces.
