Abstract
A stator for an electric rotary machine adopting a so called gap winding system in which the stator winding is arranged on the smooth inner surface of the stator core. The winding strand groups arranged on the inner surface of the annular stator core are fixedly secured to cooling pipes formed in a cylindrical frame, so that the cooling pipes support the winding strand groups thereby to facilitate transportation and assemblage of the stator winding on the one hand and to provide a sufficiently rugged stator winding to withstand the mechanical stress due to vibrations or electrical short-circuiting which are caused during the running of the electric rotary machine.
