A salient pole includes a flat coil made up of a multilayer winding of round wire. The wire includes an adhesive layer which is cured after winding to consolidate the winding. The winding is within a U-shaped channel which is impregnated with resin to fill any gaps. The flat coil fits over a pole core and is fixed thereto by means of spacers which axially space the coil from the pole core and radially space the coil from the machine casing.
