Abstract
In a stator core for a rotating electromagnetic machine, which core has two axial ends and at least one end shield at one axial end of the core, the end shield being composed of a plurality of thin plates at least one of which is a vent plate, and a vent structure supported by the vent plate, extending axially between the vent plate and an adjacent thin plate and presenting a plurality of radial flow passages for ventilating air, the vent structure is composed of: at least two elongate positioning members extending tranversely to the radial direction of the stator core, secured to the vent plate and having an axial dimension which is smaller than the axial distance between the vent plate and the adjacent thin plate; and a plurality of vent fingers extending generally in the radial direction of the core and held in position at least partially by the positioning members, each vent finger having an axial dimension equal to the axial distance between the vent plate and the adjacent thin plate and a cross section greater than that of each positioning member.
