Claims

[Scope of utility model registration request]

In a field winding that is directly cooled by providing a groove or a hole directly in the field winding itself and using the groove or hole as a cooling passage, the straight part field winding has the cooling passage inserted into a slot. A field winding for direct cooling, characterized in that each of the arcuate field windings connecting the wire and the straight field winding in the circumferential direction is separated.
