<p>An apparatus for use in producing accelerative forces comprises a fixed portion comprising a first ring-like structure (1) that supports a plurality of actuators spaced around its perimeter, each actuator comprising a generally C-shaped support frame that lies in a plane orthogonal to the ring-like support structure and orthogonal to the axis of the ring-like structure (1), each support frame carrying one or more magnets (11, 12,13, 14), and a rotating portion (2) comprising a second ring-like structure which is free to rotate around an axis and which supports a plurality of magnets 21 at spaced locations around the ring, each magnet (21) being supported on the ring-like member by a bearing such that it is free to rotate about an axis that is tangential to the ring. The two ring-like structures (1, 2) are supported relative to one another such that upon rotation of the second ring-like structure about its axis, the magnets (21) of that structure follow a path that passes through each of the actuators whereby the magnets of the actuators exert a force on the magnets (21) of the second ring-like structure which causes the magnets (21) to rotate about their axis.</p> |
