Title: Molded stator core for electric motor

Abstract: A molded stator core for an electric motor includes a stator core including a yoke and a plurality of teeth formed on an outer periphery of the yoke, the teeth having different types, and a covering member covering substantially the overall stator core and molded from an insulating resin by pouring the resin through a plurality of gates disposed so as to correspond to the yoke. In the molded stator core, an amount of resin axially flowing from each gate to the corresponding tooth of a first type is approximated to an amount of resin axially flowing from each gate to the corresponding tooth of a second type.
