PROBLEM TO BE SOLVED: To provide a rotor in which a plurality of ventilating flues for cooling are formed with a simple configuration and improvement in mechanical strength and productivity can be achieved.SOLUTION: A rotor includes a rotor core 1 having salient poles 31 to 34 having trunks 3 around which coils 5 are wound, and insulators 4 arranged and installed at the trunks 3. Respective insulators 4 are formed in inner diameter-side coil guide parts 41, 42 and outer diameter-side coil guide parts 51, 52 formed by protruding in the axial direction Z of a bottom surface part 40, respectively, and in the coil guide parts 41, 42, 51, 52 of each set, through-holes 41a, 51a, 42a, 52a penetrated in the radial direction X are formed at positions opposite to each other, respectively. Supports 6 connecting the coil guide parts 41, 42, 51, 52 in the radial direction X are inserted into the respective through-holes 41a, 51a, 42a, 52a, respectively, and formed therein. The coils 5 are wound around the lower side and the upper side of the supports 6. |
