Abstract: In the armature, a first connecting part and a second connecting part that are disposed so as to be adjacent to a connecting part of a different phase have a higher insulatable voltage value than a first leg part and a second leg part that are disposed so as to be adjacent to a leg part of the same phase.

Abstract: In this stator armature, a first leg portion has a first surface side part that has a thickness in a radial direction smaller than a thickness of a first leg portion body portion in the radial direction, a second leg portion has a second surface side part that has a thickness in the radial direction smaller than a thickness of a second leg portion body portion in the radial direction, and in the radial direction, a thickness of a joint portion is equal to or more than a thickness of a part other than the joint portion.

Abstract: In this armature, a joint portion is insulated by a joint portion insulating member that has a sheet shape and that includes a facing surface insulating part that covers a facing surface of the joint portion and a circumferential surface insulating part that covers a circumferential surface of the joint portion. The facing surface insulating parts adjacent to each other in a radial direction are connected by the circumferential surface insulating part on one side or another side in the circumferential direction.

Abstract: In this armature, between the first segment conductor and the second segment conductor that are joined to each other in the joint portion, a first clearance portion is provided between the tip end portion of the first leg portion and the second leg portion body portion in the axial direction, and a second clearance portion is provided between the tip end portion of the second leg portion and the first leg portion body portion in the axial direction.

Abstract: A rotating electrical machine stator and a method for manufacturing a rotating electrical machine stator with high productivity. A rotating electrical machine stator includes a stator core having a slot; and a coil having a leg part including a held-in-slot part held in the slot and a portion extending from the held-in-slot part, and a resin foam is provided between an inner surface of the slot and an outer surface of the held-in-slot part facing the inner surface of the slot. The coil is formed by joining together a plurality of segment conductors each having a joint part, and a conductive joint material is disposed between a pair of joint parts facing each other in the slot.

Abstract: In the stator, a slot insulating member that includes a first insulating part provided at least between an inner surface of a slot and a slot inserting part and that provides electrical isolation between a stator core and a coil part is configured to overlap an end part of an insulating coating part on a slot inserting part side of a coil end part as viewed in a direction along an end surface in an axial direction of the stator core.
