Abstract: The present invention relates to salient pole rotor for an electrical machine, e.g., a motor or generator. The rotor comprises a plurality of salient poles 1, each pole having a pole body 5 and an integral pole tip 4. The rotor further comprises a rotor winding with a plurality of coils, each coil having a plurality of turns and being positioned on the pole body 2 of a respective salient pole 1. Each pole body 2 includes a coil winding part 2A having an outer profile around which the turns of the respective coil are wound in-situ. Each turn includes two substantially straight axially-extending sides and an inner profile that differs from the outer profile of the coil winding part 2A.
