摘要： A rotor disc assembly 10 for an AC machine includes a rotor disc 20, permanent magnets 30 and a spider 40. The rotor disc 10 has a circumferential lip 22 projecting from a surface thereof. The permanent magnets 30 are positioned in a circular array on the surface of the rotor disc 20, with constant angular pitch, and so as to lie against the lip 22. The spider includes an annular base portion 41, with a plurality of arms 42 projecting radially outwards therefrom. The spider 40 is fixed to the surface of the rotor disc 20 such that each arm 42 is between and abuts a respective juxtaposed pair of the permanent magnets 30. The arms 42 and the members 30 are each provided with cooperating wedge-shaped cross sections such that each arm 42 constrains the respective two permanent magnets 30 both axially and tangentially on the surface of the rotor disc 20.

摘要： A toroidal AC generator includes an outer casing and an annular stator core of ferromagnetic material which is encased in a hollow annular cover of plastics material and which is fixed to the casing between the discs of a twin disc rotor. Each rotor disc carries a circular array of alternately polarised permanent magnets which face the stator core. The hollow annular cover is a two-part moulding and is formed of radially inner and outer ring portions which are joined by circular arrays of radial ribs which extend across the opposed radial faces of the annular core and form open-ended radial passages for the electrical phase windings which are wound around the cover. The ribs project radially beyond the radially outer ring portion and form hooks around which a winding may be retained temporarily during winding.

摘要： A rotor disc for an electrical machine is disclosed. The rotor disc comprises a series of magnetisable members arranged in a circumferential series on a surface thereof and against peripheral retaining structure of the disc. The disc also includes a retainer fixable to the surface and arranged for assisting in retaining the members at least axially on the surface when so fixed. The retainer is arranged to abut at least one of a substantially circumferentially and substantially tangentially extending, radially inner part of each member and thereby to provide the axial retention.

摘要： The stator (24) of a permanent magnet axial flux alternator comprises two annular stator components which are each wound with a respective two phase winding arrangement (48). Each of the two phase winding arrangements (48) is wound so that there is no mutual inductance between the windings of each phase. Each phase of the two phase winding arrangements (48) wound on the two stator components has a high internal impedance and is for energising a respective high intensity lamp of a light tower.

摘要： A propulsion arrangement for a marine vessel is disclosed. The propulsion arrangement comprises an engine (12, 14) for propelling the vessel and an electrical machine (26, 28) coupled to the engine. The electrical machine is arranged to supply onboard electrical power for the vessel. A control unit (44) controls the electrical machine such that the electrical machine is selectively operable as a generator or a motor. The control unit and the electrical machine are arranged such that the electrical machine when operating as a motor can supplement the power of the engine while the engine is in operation. In one embodiment, the control unit and the electrical machine are arranged to provide active damping of the engine torque.
