摘要： A vehicular AC generator has a stator coil formed by connection of four-turn phase coils by serially inserting coil conductors into slots separated by intervals of three slots, the coil conductors being arranged four in a line in a radial direction. This minimizes the crossover connection portions of the turns, to attendantly prevent a deterioration of the cooling capacity.
