Abstract:
1. A stator of a rotary electric machine, comprising: a stator core having multiple slots in a direction parallel to a rotational axis of the rotary electric machine; and a laminated flat-plate conductor formed by laminating a predetermined number of one-piece flat-plate conductors each of which has a closed end portion and an open end that opens such that the flat-plate conductor can be fitted to the stator core, wherein the laminated flat-plate conductor is inserted into the slots of the stator core and the open end is closed, whereby a coil is formed, wherein the flat-plate conductor has two sides parallel to each other, and the closed end portion between the two sides, wherein the flat-plate conductor forms a coil end, and a cross sectional area of the coil end is larger than a cross sectional area of a portion of the flat-plate conductor, which is to be inserted into the slot, the cross sectional area of the coil end being parallel to the two sides of the flat plate conductor, and the cross sectional area of a portion of the flat-plate conductor which is to be inserted into the slot being perpendicular to the sides of the flat-plate conductor, wherein each surface of the coil end is substantially flat, and wherein the coil end is substantially perpendicular to the two sides.
