Abstract: A rotor (10) for a rotating electrical machine is disclosed. The rotor comprises a plurality of salient poles (12) and rotor windings (22, 24) wound on the salient poles. A cooling vent (26) is provided through the rotor windings, the cooling vent extending through the rotor windings in an axial direction and a radial direction. The cooling vent (26) extends in an axial direction from one end of the rotor pole to the other. The cooling vent (26) may be formed by a plurality of discontinuous spacers (28), or by a spacer (78) which extends continuously around the rotor pole (12). Providing a cooling vent which extends through the rotor windings in an axial direction and a radial direction may help to improve the thermal performance of the machine in efficient and cost-effective manner.

Abstract: A component for connection between a generator and a prime mover in a power generation system is disclosed. The component may be an adaptor (20, 50, 110) or a bracket (80, 90), and may be arranged to house a fan. The component comprises a rear member (24), a front member (22), and a plurality of cross members (26) which connect the front member to the rear member. The cross members are wedge-shaped and/or lie at an angle with respect to a radial direction. The component may be arranged to surround a fan. The component may facilitate airflow and enhance thermal performance while being efficient from a structural and cost perspective.
