摘要： A separator (10, 60, 65, 100) is disclosed for electrically separating groups of end windings (52) in the stator of a rotating electrical machine. The separator is arranged to provide circumferential air channels (24, 74, 85) through the windings. This can allow air flow to be delivered to inside the windings, thereby cooling the windings more effectively.
