Claims

[Scope of utility model registration request]

It has a coil wound around a large number of grooves provided on the outer periphery,
and, in an iron core of a rotating electric machine in which a plurality of ventilation ducts are formed along the longitudinal direction, a fill-winding groove of each unit core between the ventilation ducts is a first groove for fixing the coil with a wedge; A second groove, which is larger than the first groove and can form a predetermined gap with the outer periphery of the coil, is mixed along the circumferential direction, and the gap is configured to allow cooling air to flow therethrough. Characteristic iron core of rotating electric machines.
