優れ、高信頼性の回転電機を提供することができる。Furthermore, in this embodiment, the rotor coil lead wire and the slip ring terminal are electrically and mechanically connected by so-called pressure current welding via solder, which can achieve high heat resistance and high bonding strength, and furthermore, the slip ring terminal is connected electrically and mechanically. The tip 128' of the ring terminal is shaped like a flat plate, and the folded rotor coil outlet wire 6a is crossed and brought into contact with the tip 12a' of this flat plate-shaped slip ring terminal via preliminary solder. 6a and the linear terminal tip 128' can be secured sufficiently, so that connection reliability can be improved. Therefore, even if the rotating electrical machine is installed in a place with high temperature and vibration, such as a vehicle alternator, it is possible to provide a rotating electrical machine with excellent environmental resistance and high reliability. .
