PROBLEM TO BE SOLVED: To improve cooling and radiating of a stator coil by increasing the cooling and radiating surface of the stator coil. SOLUTION: At least one of the ends 2a of a coil, that is wound in the slots in a stator core 1 and is protruded from both ends of the stator core 1 in a bundle, is divided into at least two in the radial direction, and a space 5, through which cooling air, is passed is formed between the divided coil ends 2a.
