Abstract
A stator of a dynamoelectric rotary machine includes a stator body which has substantially axially extending slots, a stator winding, the conductors of which are located in the slots and spacers for positioning the conductors in the slots such that a cavity for the passage of a cooling medium that is continuous over the entire axial length of the slot, remains between the slot walls and the conductors. The stator body is a laminated core having stator sheets stacked axially on top of one another and intermediate sheets that act as spacers located between the stator sheets, the intermediate sheets being axially spaced apart from one another over a plurality of stator sheets and having retainers for retaining and positioning the conductors such that, between each pair of intermediate sheets, the conductors are positioned spaced apart from the walls of the slot in a free-floating manner.
