Abstract (en)
[origin: WO2022238681A1] A spacer is disclosed for forming an axial cooling vent between two sets of side windings in a rotor of a rotating electrical machine. The spacer (50; 60; 70; 80; 90) comprises a plurality of air passages (58; 68; 78; 88; 94) for axial air flow through the spacer. The air passages are at least partially open towards the windings. This can allow air flow through the spacer to contact the windings, thereby improving cooling efficiency.
