A solder material (Pb-8n type) is sandwiched between the solder materials 12a via preliminary solder plating, and first, the elements in the solder components are reacted with the base material by heating with electricity. This reaction creates an alloy layer (Cu-Sn or Cn-
S n −A g ) is formed between the parts to be joined. After that, heat and pressure are applied to the main component of the low-melting, low-strength solder (
pb) is melted and discharged outside the joint surface. The alloy layer thus formed between the joints has an extremely high joint strength of 12 kgf/2 or more at room temperature.

はなく母材が破断する程に接合力が強く。Even in a tensile test under a high-temperature atmosphere of 250°C, the bonding force is so strong that the base material breaks, not the joint.
高耐熱、高強度接合を実現できるものである。This makes it possible to achieve high heat resistance and high strength bonding.

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. .
