Abstract
The effects of operational loading on a permanent magnet generator of the type having first and second permanent magnet assemblies 28, 30 mounted on a shaft 26, and movable relative to each other is eliminated by rotatably mounting each of the assemblies 28, 30 for rotation relative to the shaft 26, as well as to each other, and connecting them to the shaft by equal, but oppositely pitched helical spline connections 50, 52, 58, 60. Axial movement of the shaft 26 will then cause equal, but opposite relative movement of the permanent magnet assemblies 28, 30, so that the forces resisting movement of one such assembly act to encourage movement of the other, thereby balancing out said forces.
