ABSTRACT:
To secure insulation between electrical conductors at a coil end, a first electrical conductor at one coil end is arranged so as to intersect a radially adjacent second electrical conductor at one point or more. The electrical conductor is formed with radial indentations in side faces that are opposite side faces in opposing electrical conductors at any of the intersecting portions, the indentations having depths that increase toward the near end of the electrical conductors. Sufficient clearances are thereby secured between electrical conductors in their intersecting portions near their ends where the insulating films are susceptible to damage because of welding heat. Electrical insulation is thus ensured, and the cooling efficiency at the coil end is improved.
