摘要： A stator for a rotary electric machine includes: a collar portion provided at an end portion of each of the tooth portions so as to project to the slot side and includes: a connection portion; a bent portion extending in the circumferential direction and forming a first gap; and a stop portion projecting at an end side thereof in the circumferential direction to the slot side and formed so as to have a width in the radial direction larger than a width in the radial direction of the bent portion. An R dimension of a side surface, in the circumferential direction and at a side opposite to a projection side of the tooth portion, of the bent portion is not less than the width in the radial direction of the bent portion.

摘要： This rotor includes: a rotor core in which a plurality of insertion holes each penetrating the rotor core in an axial direction are formed with intervals interposed thereamong in a circumferential direction; and magnets respectively provided in the insertion holes, wherein a hole-inside-peripheral-surface of each insertion hole does not contact with a magnet-inside-peripheral-surface of a corresponding one of the magnets, a hole-outside-peripheral-surface of the insertion hole and a magnet-outside-peripheral-surface of the magnet contact with each other at two locations of a first location and a second location, an adhesive layer portion is formed between the first location and the second location and between the hole-outside-peripheral-surface of the insertion hole and the magnet-outside-peripheral-surface of the magnet, and a first protruding portion which protrudes toward outside in a radial direction and which contacts with the magnet is formed at the hole-inside-peripheral-surface of the insertion hole.

摘要： The rotor includes: a rotor core having a plurality of insertion holes penetrating in an axial direction at intervals in a circumferential direction; and magnets respectively provided in the insertion holes. A space is formed between a hole inner side peripheral surface of each insertion hole and a magnet inner side peripheral surface of each magnet. An adhesion layer portion is formed between a hole outer side peripheral surface of each insertion hole and a magnet outer side peripheral surface of each magnet, and the hole outer side peripheral surface of each insertion hole and the magnet outer side peripheral surface of each magnet with which the adhesion layer portion contacts are formed in a flat-surface shape. A width in a radial direction of the space is longer than a width in the radial direction of the adhesion layer portion.

摘要： A tooth groove is provided at a border portion between a tooth body portion and a protrusion. The angle between a tooth body portion lateral face which is a lateral face in the circumferential direction of the tooth body portion and a tooth body portion stop portion which is a face, of the tooth groove, continued from the tooth body portion lateral face is the right angle or an acute angle. The protrusion is rotated toward the outer side in the circumferential direction, to bring a protrusion stop portion into close contact with the tooth body portion stop portion, the protrusion stop portion being an outer-circumferential-side lateral face of the protrusion, thereby forming a shoe in a tooth.
