PURPOSE:To prevent the tooth sections of a core end from being superheated, by a method wherein filler blocks are provided with a mechanism for ventilating the teeth of the stator core end forcibly according to the rotation of a rotor. CONSTITUTION:Two filler blocks 8a, 8b are radially provided for the tooth sections 1, 2 at the end of a stator core 6, and a slit 9 for ventilation is formed near the center of the tooth of the filler block 8a facing the tooth flange section which is specially superheated, and the front and lower parts of the slit are covered in a bag form with a core keeper 7. As the result, the superheated sections of the teeth are forcibly cooled by cooling air flowing through the slit 9 in the direction of the arrow head from upper parts according to the rotation of a rotor. |
