Abstract

A stator includes an annular substrate, an outer-diameter portion of the substrate provided at a tip end of an outer-diameter leg of a bobbin, the substrate having a smaller inner diameter than an inner diameter of the stator core. When stator resin provides sealing, the outer-diameter portion of the substrate can be supported by the tip end of the outer-diameter leg of the bobbin, and an inner-diameter portion of the substrate can be supported by a mold. Accordingly, even when the moment of inertia of a molded motor is increased, the substrate can be prevented from being deformed by a molding pressure with the stator resin, without the area of the substrate being decreased.
