ABSTRACT:
In a gap winding type electric rotary machine, a stator winding consisting of a plurality of stator coils is mounted on the inner surface of a stator core within the air gap defined by the clearance between the stator core and the rotor core, in such a manner that the stator coils are grouped together in a plurality of stator coil units and each stator coil unit is encapsulated in a solid casing comprising an outer cover fixed to the inner surface of the stator core through an elastic sheet and an inner cover closing the outer cover. The inner clearance within the solid casing is also provided with an elastic sheet.
