Abstract: A first molded coil that is one of two molded coils disposed adjacent to each other includes: a first winding part in which a conductor is stacked from a first turn to an n-th turn (n is an integer of 2 or more); and a first terminal part that has a lead part extending from a portion of the first turn of the first winding part in a direction orthogonal to a stacking direction of the conductor in the first winding part, in which the first terminal part is provided at a tip with a first engaging part that is engaged with a second engaging part disposed at a tip of a third terminal part of a second molded coil that is the other molded coil of the two molded coils.

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: Provided are a stator capable of substantially preventing a decrease in torque and a rotary electric machine including the stator. A stator includes a stator core, an insulator, and a coil. The stator core includes: a yoke having an annular shape; and teeth protruding from the yoke to the inside of the yoke. The insulator covers at least a part of the stator core. The insulator includes: a first face facing the coil wound around the teeth; and a second face facing the yoke. The first face is perpendicular to the protrusion direction of the teeth. The second face includes: a first perpendicular face perpendicular to the protrusion direction of the teeth; and a first inclined face inclined toward the first face with respect to the first perpendicular face. The yoke includes an inner circumferential face facing the second face.

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.
