摘要： PROBLEM TO BE SOLVED: To provide a stator of a rotating electric machine and a rotating electric machine which are capable of reducing costs and securing a creepage distance.SOLUTION: A stator 11 includes a stator core 110, a stator winding 111, and an insulating paper 112. With respect to the stator winding 111, conductor segments 111a are respectively inserted into slots from a lower end side of the stator core 110, and their front ends projecting at an upper end side are joined to constitute respective phase windings, and the phase windings are Y-connected to constitute the stator winding 111. The insulating paper 112 is disposed between junction portions adjacent to each other in a radial direction among junction portions 111k-111o constituting a junction group closest to a U-phase terminal. The same is true for a V-phase winding and a W-phase winding. Surfaces of the other junction parts are respectively covered with insulating resins 113. The insulating paper 112 is disposed between junction parts requiring a long creepage distance but the other junction parts not requiring a long creepage distance have surfaces covered with the insulating resin 113. Therefore, a configuration is simplified to reduce a cost and a required creepage distance can be secured.

摘要： PROBLEM TO BE SOLVED: To average an anti-magnetic field that a stator exerts on a permanent magnet and reduce the maximum value of the anti-magnetic field exerted on the permanent magnet in a rotor of a permanent magnet type rotary electrical machine.SOLUTION: A first corner 20c is the farthest corner from the outer peripheral surface 9a of a rotor core 9. A second corner 20d is located at a counter position to the first corner 20c in the magnetization direction of a permanent magnet 10. Between the second corner 20d and a slot inner peripheral surface 25, a gap 31 is provided. A slot inner peripheral surface 25a facing the second corner 20d through the gap 31 is an arc face whose center is a point X on the slot inner peripheral surface 25 facing the first corner 20c. Thus, magnetic resistance in the vicinity of the second corner 20d is averaged and the magnetic flux from a stator side is dispersed, allowing an anti-magnetic field to be averagely applied over the wide range of the permanent magnet 10. As a result, the maximum value of the anti-magnetic field can be reduced.

摘要： PROBLEM TO BE SOLVED: To average an anti-magnetic field which a permanent magnet receives from a stator to reduce the maximum value of the anti-magnetic field which the permanent magnet receives in a rotor of a rotary electric machine.SOLUTION: When a corner part 20a closest to an outer peripheral surface 9a of a rotor core 9 is considered as a first corner part, and a side surface 17a which forms the first corner part, has a virtual line Q in a magnetization direction passing through the center of a permanent magnet 10 crossing, and turns to the stator side is considered as a first side surface, a rotor has, between the first side surface and a slot inner peripheral surfaces 25 in order from the first corner part: a first gap 31 which separates the first side surface from a slot inner peripheral surface 25a; and a second gap 32 which separates the first side surface from a slot inner peripheral surface 25b and is connected to the first gap 31. Gap width h1 of the first gap 31 is smaller than gap width h2 of the second gap 32. Thus, the rotor core 9 near the first gap 31 is widely secured. As a result, magnetic saturation of the rotor core 9 near the first gap 31 is alleviated, and an anti-magnetic field to be applied to the permanent magnet 10 is averaged.
