Abstract
A stator may comprise: a core having a tubular shape and comprising a tooth extending toward a central axis of the tubular shape; a conducting wire engaging part projecting from an axial end of the core in an axially outward direction from the core; and a coil disposed on the tooth by winding a conducting wire on the tooth. An end of the conducting wire may be bent at a bending portion. The conducting wire may engage with the conducting wire engaging part at the bending portion. A diameter of the conducting wire at the bending portion may be smaller than a diameter of the conducting wire at another portion of the conducting wire.
