The object of the invention is to improve operability of the process for inserting the coil conductor into the insulating member stored inside the slot of the rotor core. Each of the first insulating member and the second insulating member has one side arranged between the first coil and the second coil so that the respective sides are superposed along the radial direction of the stator core. The side of the first insulating member and the side of the second insulating member are connected with the first connection part at one end in the longitudinal direction.

Stator for rotary electric machine, method of manufacturing stator for rotary electric machine, and rotary electric machine

Provided are a rotor of a rotary electrical machine, a rotary electrical machine, and a vehicle, which enable mitigation of stress concentration generated in a magnet insertion hole of a rotor core and high-speed rotation. A rotorof a rotary electrical machine includes: a rotor coreincluding a plurality of magnet insertion holesfor each magnetic pole; and permanent magnetsinserted into the magnet insertion holes, in which a bridge portion, which mechanically connects a rotor core portionon the outer circumferential side of the magnet insertion holesand a rotor core portionon the inner circumferential side of the magnet insertion holes, is provided between the adjacent magnet insertion holes, and the bridge portionhas two inflection pointsandon the outer circumferential side of the bridge portion

Rotor of rotary electrical machine, rotary electrical machine, and vehicle

The efficiency of inserting a coil conductor into a slot of a stator core is improved in the present invention. Included are a rotor and a stator. The stator includes a stator core formed with a plurality of slots formed at a predetermined depth in a radial direction and arranged while spaced apart from each other in a circumferential direction and stator winding having a coil conductor inserted in each of the slots. A plurality of protrusions are formed in each of the slots of the stator core toward a space into which the coil conductor is inserted.

Rotating electric machine

TIG welding can be applied, and short circuiting of stator winding due to a jointing material of coil conductors is prevented. A rotating electric machine includes a rotor; and a stator having a stator core and a stator winding, wherein the stator winding has a plurality of coil conductors, and joint parts connecting ends of the coil conductors protruding from an end face of the stator core, and the ends of the coil conductors have weir portions formed for blocking flow of metal of the joint parts.
