Abstract: A bus bar guide is provided to fix bus bars that connect a plurality of coils disposed in a motor. The bus bar includes a conductor that has a plate shape and has a first surface and a second surface continuous with the first surface. The bus bar guide is configured by annularly arranging a plurality of bus bar guide pieces each including an insulator. Each of the plurality of bus bar guide pieces is provided with a groove that holds the first surface of the bus bar and positions the bus bar.

Abstract: A coil is a coil of a conductive wire that has a quadrangular cross section, that is spirally wound and laminated to have a series of turns including first to n-th turns (n is an integer of 3 or more), and that is provided, on at least some of the first to n-th turns in the coil, with deformed portions representing recesses each having a shape different from a shape of another portion of the conductive wire. In each of the first and n-th turns respectively lying at both ends of the series of turns, an outer surface lying on a side opposite to a center of the series of turns extends flush along with a plane intersecting the series of turns.

Abstract: A stator includes a yoke, teeth connected to the yoke, and coils including plate-shaped conductive wire and mounted on respective teeth. Each coil includes a wound part, a first and second terminals. The wound part is wound around the tooth n turns (n is an integer equal to or greater than 2). The wound part satisfies a relationship represented by Ak
