Abstract
A stator for an electric rotary machine which includes a stator coil which is made up of conducting wires each of which includes in-slot portions disposed one in each of slots formed in a stator core and turned portions each of which connects adjacent two of the in-slot portions outside the slots. Each of the turned portions includes steps adjacent connected through a curved bend. The curved bend of one of the conducting wires is laid to overlap one of turned portions of the other conducting wire in an axial direction of the stator core through a gap. The curved bend has walls extending toward one of the turned portions of the other conducting wire to define a chamber. The walls increase a total area of the stator coil from which thermal energy will dissipate, thus enhancing the ability of the stator coil to be cooled.
