Abstract:
1. A rotary generator comprising at least one-air-cored coil assembly comprising a plurality of current conducting coils, and a plurality of magnetic flux conducting units, each of the plurality of magnetic flux conducting units comprising: at least one magnet; a pair of opposed magnetic flux conducting elements of iron or ferrous alloy defining a space therebetween for receiving the at least one air-cored coil assembly; and at least one connecting portion extending between the opposed magnetic flux conducting elements; wherein the at least one magnet is arranged relative to the opposed magnetic flux conducting elements such that magnetic attraction forces between the elements are reacted through and balanced within the connecting portion, the rotary generator comprising a rotor and a stator, one of the rotor and the stator carrying the plurality of flux conducting units and the other of the rotor and the stator carrying the at least one air-cored coil assembly, the rotor configured to be coupled to a drive member of a prime mover of a power generation machine and thereby configured for rotation relative to the stator, and wherein the plurality of flux conducting units are arranged circumferentially around the circumference of a disc of the rotor or the stator.
