Abstract
An electrical generator (1) comprising first and second relatively rotatable winding assemblies (5,8), the first winding assembly (5) having a first electrical output for connection to a first electrical load (4) and the second winding assembly (8) having a second electrical output for connection to a second electrical load (6 or 19), and a permanent magnet assembly (12) freely rotatably mounted between the winding assemblies (5,8) such that, in use, rotation of the winding assemblies (5,8) relative to the permanent magnet (12) assembly induces a current in both winding assemblies. A third winding assembly (19) may rotate with the second winding assembly (8) relative to a fourth winding assembly (20) that rotates into the first winding assembly (5). The third winding assembly 19, may comprise said second electrical load, and the fourth winding assembly (20) may be connected to a fourth electrical load (22,23). The first and fourth electrical loads (4,22,23) may be de-icing elements on a propeller.
