Abstract: A coil (80) for an electric machine (18) including a conductive strand (82) having a first end, a second end, and a plurality of windings (84) between the first and second ends and an electric insulating body (94) within which the conductive strand (82) is at least partially encased, wherein at least a portion of the insulating body (94) includes perforations (96) that allow a coolant to penetrate into the insulating body (94) to cool the coil (80) during use of the electric machine (18). A method of making the coil (80) includes moulding or printing the insulating body (94) about the conductive strand (82) so as to have perforations therein.

Abstract: Aspects of the present invention relate to a rotor arrangement (42) for a wind turbine generator (24). The rotor arrangement (42) comprises a cylindrical ring structure (46) arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises: a plurality of ring-shaped permanent magnet packages (48) arranged coaxially around the rotational axis, a plurality of tie rods (55) extending axially through the plurality of permanent magnet packages (48) to join the plurality of permanent magnet packages (48) together; and one or more spacer components (64; 164) located between at least one axially adjacent pair of the plurality of permanent magnet packages (48) to space the respective pair of permanent magnet packages (48) apart, wherein the one or more spacer components (64; 164) are configured to act as an impeller as the rotor rotates, in use, thereby to cause air to flow in a radial direction, with respect to the rotational axis of the rotor arrangement (42), between the at least one axially adjacent pair of permanent magnet packages (48). The generator rotor arrangement uses a portion of the kinetic energy of the rotating rotor arrangement to generate a radial air flow that flows between and/or around the magnet packages to transfer heat away from the magnet packages, and thereby to provide a cooling function.
