Plural slots are formed in a cylindrical stator or rotor core of a rotary electric machine. An insulation sleeve having a substantially rectangular cross-section is inserted into each slot, and conductors are inserted into an inner space of the insulation sleeve disposed in the slot. The inner space of the insulation sleeve is enlarged by inserting the conductors, thereby strongly pressing the corner portions of the insulation sleeve against the corners of the slot. Thus, the insulation sleeve is firmly kept in the slot, avoiding its sliding movement in the slot in the process of inserting the conductors. The insulation sleeve is prevented from being damaged by its sliding movement in the slot. |
